Title: Pannier and vehicle including the same

Description:
CROSS REFERENCE TO THE RELATED APPLICATION 
     This application is based on and claims Convention priority to Japanese patent application No. 2021-009895, filed Jan. 25, 2021, the entire disclosure of which is herein incorporated by reference as a part of this application. 
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present disclosure relates to a pannier for item storage which is attached to a vehicle. 
     Description of Related Art 
     Some vehicles such as saddle-riding vehicles have been known in which panniers for item storage are attached to lateral sides at the rear of the vehicles (for example, JP Examined Patent Publication No. S61-043237, International Patent Publication No. WO 2015/140380). A pannier includes a casing body in which an item storage space is defined and a lid member which opens and closes an opening of the casing body. 
     For antitheft purposes, such a pannier can be locked at an attaching-detaching mechanism which allows the casing body to be attached to and detached from the vehicle body as well as at an opening-closing mechanism which allows the lid member to open and close the casing body. Due to the locking structure in the attaching-detaching mechanism and the opening-closing mechanism, on the other hand, the pannier includes an increased number of components. 
     SUMMARY OF THE INVENTION 
     The present disclosure provides a pannier which can have a reduced number of components as well as a saddle-riding vehicle including the same. 
     The pannier according to the present disclosure is a pannier for item storage to be attached to a vehicle, the pannier including: a casing body which defines a storage space which receives an item and includes an opening through which the item is placed into and taken out from the storage space; a lid which closes the opening of the casing body; an attaching-detaching holder which removably attaches the casing body to the vehicle; an opening-closing holder which attaches the lid to the casing body in an openable and closeable manner; a cylinder which serves to lock both of the attaching-detaching holder and the opening-closing holder; and a movable holder which is movable when the cylinder is unlocked. The cylinder is turned to a lock position, a pannier detaching position and a pannier opening position. When the cylinder is at the lock position, the movable holder is retained by the cylinder at a position where the casing body is unremovable from the vehicle and the lid is unopenable with respect to the casing body. When the cylinder is at the pannier detaching position, the movable holder is movable to an attachable-detachable position where the movable holder allows the casing body to be attached to and detached from the vehicle. When the cylinder is at the pannier opening position, the movable holder is movable to an openable position where the movable holder allows the lid to be opened with respect to the casing body. 
     According to this constitution, it is possible to lock and unlock the pannier for attachment to and detachment from the vehicle as well as the lid for opening and closing through a turning operation of the single cylinder. Therefore, as compared with a case where the pannier includes separate lock structures for these operations, the pannier includes a reduced number of components and have improved handleability. 
     The present disclosure encompasses any combination of at least two features disclosed in the claims and/or the specification and/or the drawings. In particular, any combination of two or more of the appended claims should be equally construed as included within the scope of the present disclosure.

     DESCRIPTION OF THE EMBODIMENTS 
     Hereinafter, a preferred embodiment of the present disclosure will be described with reference to the drawings.  FIG. 1  is a side view showing a rear part of a motorcycle which is a type of vehicle including a pannier according to a first embodiment of the present disclosure. In the present specification, the “left” and “right” sides correspond to the “left” and “right” sides as viewed by a driver on the vehicle, respectively. The “front” and “rear” correspond to the “front” and “rear” in a direction of movement of the vehicle, respectively. Further, with respect to a vehicle widthwise direction, an inner side in the vehicle widthwise direction refers to a side closer to a center line in the vehicle widthwise direction, the center line extending in a front-rear direction or longitudinal direction of the vehicle, and an outer side in the vehicle widthwise direction refers to a side away from the center line in the vehicle widthwise direction. Unless otherwise noted, a front-rear direction, a widthwise direction, and a vertical direction of the pannier refer to those directions when the pannier is mounted on the vehicle. 
     The motorcycle according to the present embodiment includes a vehicle body frame FR including a main frame  1  that is a front half of the vehicle body frame FR and a rear frame  2  that is a rear half of the vehicle body frame FR. The main frame  1  extends rearward and diagonally downward from a head pipe (not illustrated) at a front end and then is curved downward to extend in the vertical direction. The head pipe supports a front fork (not illustrated) which supports a front wheel (not illustrated) at a lower end portion of the front fork, and handle bars (not illustrated) is attached to an upper end portion of the front fork. 
     A swingarm bracket  4  is located at a rear end portion of the main frame  1 . The swingarm bracket  4  supports a swingarm  6  in such a way that the swingarm can swing in the vertical direction. The swingarm  6  includes a rear end portion to which a rear wheel  8  is attached. The rear frame  2  extends rearward from a rear part of the main frame  1 . In the present embodiment, the rear frame  2  includes a pair of left and right portions. Specifically, as shown in  FIG. 2 , the rear frame  2  includes left and right rear frame pieces  2   a ,  2   a.    
     An engine E, which is a drive source, is mounted below the main frame  1  and in front of the swingarm bracket  4  as shown in  FIG. 1 . The engine E drives the rear wheel  8  through a power transmission member (not illustrated) such as a chain. A fuel tank  10  is disposed in an upper part of the main frame  1 , and a seat  12  on which a driver sits is attached to the rear frame  2 . In the present embodiment, the seat  12  is a double seat including a rider seat part for a driver and a tandem seat part for a passenger. Alternatively, the rider seat and the tandem seat may be separate parts. 
     A pannier  14  for item storage is attached to a lateral side of the rear part of the vehicle body. As shown in  FIG. 2 , such panniers  14  are attached to left and right sides of the tandem seat part at a rear part of the seat  12 . The pannier  14  has a substantially cuboid shape which is long in the front-rear direction or longitudinal direction of the vehicle body when mounted on the motorcycle. The pannier  14  is supported by the rear frame  2  through a pannier stay  16 . The support structure for the pannier  14  will be described later. The pannier stay  16  is removably attached to the rear frame  2  by a fastener (not illustrated) such as a bolt. 
     The pannier stay  16  is, for example, a steep pipe member and includes a front end portion  16   a  which is fastened to the rear frame  2 . Specifically, the pannier stay  16  includes: a first part  31  extending outward in the vehicle widthwise direction from the front end portion  16   a ; a second part  32  extending diagonally upward to the rear from an outer end  31   a  of the first part  31 ; and a third part  33  extending rearward from an upper end  32   a  of the second part  32 . To an upper portion of the second part  32  and a rear portion of the third part  33 , support members  34  extending inward in the vehicle widthwise direction are connected at their outer end portions in the vehicle widthwise direction, which are one end portions of the support members. The support members  34  are fastened to the rear frame  2  at their inner end portions  34   a  in the vehicle widthwise direction, which are the other end portions of the support members. 
     A carriage plate  18  is located in the rear of the seat  12  and is supported by the rear frame  2 . For example, the carriage plate  18  may be used for carrying luggage. A top casing  20  for item storage can be attached to the carriage plate  18 . The top casing  20  is disposed between the left and right panniers  14 ,  14 . 
     As shown in  FIG. 1 , each pannier  14  has a flat upper face  14   a  which is located higher than an upper face  12   a  of the seat  12  when the pannier is mounted on the vehicle. Thus, a long item B can be placed in the vehicle widthwise direction on upper faces of the left and right panniers  14 ,  14 . 
     Each pannier  14  is shaped as a resin box and includes a casing body  22  and a lid  24  or lid member  24 . Inside the casing body  22 , a storage space S 1  is defined for item storage. The casing body  22  includes, at an upper end thereof, an opening  22   a  through which an item is placed into or taken out from the storage space S 1 . 
     A protection member  26  is removably attached to an outer lateral face of the casing body  22  in the vehicle widthwise direction. The protection member  26  is removably attached to the casing body  22  by means of a fastener (not illustrated) such as a bolt. The attachment structure of the protection member  26  is not limited to this type. The protection member  26  on the outer lateral face of the casing body  22  can protect a part of the casing body  22  which is prone to damage. Thus, even when the pannier  14  gets a scratch, it is only necessary to replace the protection member  26 , instead of the whole pannier  14 . 
     As shown in  FIG. 3 , the casing body  22  includes legs  28  for self-support on the bottom face thereof. The legs  28  protrude downward from the bottom face of the casing body  22 . In the present embodiment, the legs  28  are integrated with the casing body  22 . The legs  28  are located at three positions, namely, at a front end portion, a rear end portion and an outer end portion in the vehicle widthwise direction on the bottom face of the casing body  22 . The number and positions of the legs  28  are not limited to those of the present embodiment. Thanks to the legs  28  on the bottom face of the casing body  22 , the pannier  14  can stand on its own on the ground, so that it is easy to handle. 
     The casing body  22  includes a casing-side handle  30  on a rear face thereof. The handle  30  is located at an upper part of the rear face of the casing body  22  and includes an opening  30   a  which opens downward. In other words, the handle  30  is arranged at the upper part of the rear face of casing body  22  and is shaped like a pocket which opens downward. When the pannier  14  is detached from the vehicle, a user may insert fingers into the opening  30   a  of the handle  30  to hold the handle  30  with the fingers and lift up the pannier  14 , so that the pannier  14  can be carried. 
     When the pannier  14  is supported on the vehicle with a second holding member or movable holder (which will be described later) released so as not to effect holding, the user may hold the handle  30  with the fingers to lift up the pannier  14  and detach it from the vehicle. Thus, the handle  30  may be used when the pannier  14  is carried and when the pannier  14  is detached from the vehicle body. In this way, the structure can be simplified in that a same part can serve for both transport and detachment of the pannier  14 . 
     As shown in  FIG. 4 , the casing body  22  includes, on an inner lateral face thereof in the vehicle widthwise direction, a to-be-supported body  35  to be supported by the vehicle body. In the present embodiment, there are three to-be-supported bodies  35 , namely, first to third to-be-supported bodies  36 ,  37 ,  38 . 
     The first to-be-supported body  36  is located at a lower position of a front end portion of the inner lateral face of the casing body  22 . The second and third to-be-supported bodies  37 ,  38  are located at an upper end portion of the inner lateral face of the casing body  22  and are arranged in line in the front-rear direction, with the second to-be-supported body  37  located at a forward position. Thus, the to-be-supported bodies  36 ,  37 ,  38  are arranged at two separate positions in the front-rear direction and at two separate positions in the vertical direction. The number and positions of the to-be-supported bodies  36  to  38  are not limited to those of the present embodiment. 
     In the present embodiment, the first to third to-be-supported bodies  36 ,  37 ,  38  are integrally formed with the casing body  22  by molding. The first to-be-supported body  36  protrudes inward in the vehicle widthwise direction from the inner lateral face of the casing body  22  and includes a first recess part  36   a  which opens forward. The second and third to-be-supported bodies  37 ,  38  protrude inward in the vehicle widthwise direction from the inner lateral face of the casing body  22  and include second and third recess parts  37   a ,  38   a , respectively, which open downward. The second recess part  37   a  and the third recess part  38   a  are located at an interval in the front-rear direction. 
     The pannier stay  16  includes a front-rear part extending in the front-rear direction and a bent part extending downward from a front end portion of the front-rear part. The pannier  14  is brought closer to the pannier stay  16  from above, and the second recess part  37   a  and the second recess part  38   a  are fitted to a front part and a rear part of the pannier stay  16 , respectively. Thus, the pannier  14  is supported by pannier stay  16  from below. Then, the pannier  14  is moved forward from the rear of the bent part of the pannier stay  16 , such that the first recess part  36   a  is fitted to the bent part of the pannier stay  16 . Thus, the pannier  14  is restricted by the pannier stay  16 , so that the pannier  14  is prevented from moving forward. 
     The lid  24  as shown in  FIG. 1  closes an opening  22   a  of the casing body  22 . Hereinafter, the expression “the lid closes” or the like may sometimes be used to describe a state where the lid  24  closes the opening  22   a  of the casing body  22 . Also, the expression “the lid opens” or the like may sometimes be used to describe a state where the lid  24  opens the opening  22   a  of the casing body  22 . The lid  24  includes an opening-closing holder or an opening-closing mechanism which attaches the lid to the casing body  22  in an openable and closeable manner. The opening-closing holder includes a hinge  40  and an opening prevention part  42 . The hinge  40  is located at a front part of the pannier  14 . Specifically, the hinge  40  connects an upper front end portion of the casing body  22  to a lower front end portion of the lid  24  and has a hinge axis line extending in the left-right direction or vehicle widthwise direction at the connection part. The hinge  40  is connected such that a part of the hinge which is located on the side of the lid  24  can be angularly displaced about the hinge axis line with respect to another part of the hinge which is located on the side of the casing body  22 . Thus, the lid  24  is attached to the casing body  22  through the hinge  40  so as to be openable and closeable. 
     The opening prevention part  42  is located at a rear part of the pannier  14 . The opening prevention part  42  includes a casing-side section located on the side of the casing body  22  and a lid-side section located on the side of the lid  24 . When the casing-side section and the lid-side section of the opening prevention part  42  are engaged with each other with the lid  24  closing the casing body  22 , this engagement prevents angular displacement of the lid  24  with respect to the casing body  22 , so that the casing body  22  is prevented from opening. When the engagement between the casing-side section and the lid-side section of the opening prevention part  42  is released, the lid  24  is allowed to be angularly displaced with respect to the casing body  22 , so that the casing body  22  can be opened. Thus, the lid  24  can be switched between a unopenable-unclosable state and an openable-closable state by the opening prevention part  42 . The opening prevention part  42  will be described in detail later. 
     As shown in  FIG. 3 , the hinge  40  includes: a first hinge member  44  which is attached to the casing body  22 ; a second hinge member  46  which is attached to the lid  24 ; and a hinge shaft  45  which couples the hinge members  44 ,  46  in a turnable manner. The hinge shaft  45  extends in the vehicle widthwise direction. To open the casing body  22 , the lid  24  is angularly displaced about the hinge shaft from a state where the lid  24  closes the casing body  22 , such that a rear end portion of the lid  24  is moved forward. Accordingly, the lid  24  is constructed to be opened from the rear to the front. This can prevent the lid  24  from opening due to wind during traveling. 
     As indicated with a double dotted line in  FIG. 1 , an upper face  44   a  of the first hinge member  44  on the side of the casing body  22  is inclined upward to the front. When the lid  24  is opened, a front face of the lid  24  comes into contact with the upper face  44   a  of the first hinge member  44 . Thus, the lid  24  can be held at a predetermined position, so that the lid  24  can be prevented from opening excessively. 
     The lid  24  includes a tab part  23  ( FIG. 3 ) on a rear face thereof. The tab part  23  is located at a lower part of the rear face of the lid  24  and includes an opening which opens downward. In other words, the tab part  23  is arranged at the lower part of the rear face of the lid  24  and is shaped like a pocket which opens downward. With a first holding member or first movable holder (which will be described later) released so as not to effect holding, a user may insert fingers into the opening of the tab part  23  to hold the tab part  23  with the fingers and raise the lid  24 , so that the lid  24  can be more easily displaced angularly. In the present embodiment, the tab part  23  of the lid  24  is located above the handle  30  of the casing body  22  and adjacent to the handle  30 . 
     As shown in  FIG. 5 , the lid-side section of the opening prevention part  42  is located at the rear end portion of the lid  24 . The casing-side section of the opening prevention part  42  is located opposite to the lid-side section and at an upper rear end portion of the casing body  22 . When the lid-side section of the opening prevention part  42  is held with respect to the casing-side section of the opening prevention part, the lid  24  is prevented from opening the casing body  22 . 
     As shown in  FIG. 9A  to  FIG. 9C , in the present embodiment, the lid-side section  100  of the opening prevention part  42  includes first holding pieces  48 , a coupling piece  102 , a first operating piece  50 , and a first spring body  52 . In the present embodiment, there are two such first holding pieces  48  or first holding elements  48  arranged in the vehicle widthwise direction. The coupling piece  102  couples the respective first holding pieces  48  to the first operating piece  50  and extends in the vehicle widthwise direction. Therefore, the first holding pieces  48 , the coupling piece  102  and the first operating piece  50  are realized as a single first movable holder  104 . Accordingly, the first holding pieces  48  are displaced in conjunction with a displacing operation of the first operating piece  50 . 
     The first movable holder  104  is housed in a first guide space S 2  defined in the lid  24  and is guided in a displaceable manner in the vehicle widthwise direction within a predefined allowable range. In other words, the first movable holder  104  is housed in the first guide space S 2  of the lid  24 , so that the first movable holder  104  is prevented from being displaced in other directions than the vehicle widthwise direction. 
     When an operator displaces the first operating piece  50  in the vehicle widthwise direction, the first holding pieces  48  coupled to the first operating piece  50  are moved in the vehicle widthwise direction. The first operating piece  50  is arranged at a position where it is exposed on a rear face of the lid  24 . In the present embodiment, the first operating piece  50  is located adjacent to a cylinder  69  which will be described later, and is exposed at a portion which is located on the side of the vehicle body on the rear face of the lid  24  and at a side face of the lid  24  which is located on the side of the vehicle body. The first operating piece  50  has a hook shape and includes a recess  106  which can receive a finger approaching from the rear. In an unlocked state as described later, the finger inserted into the recess  106  of the first operating piece  50  may apply a force acting inward in the vehicle widthwise direction to a body-side inner surface of the recess  106  so as to move the first holding pieces  48  inward in the vehicle widthwise direction in conjunction with the first operating piece  50 . 
     The first movable holder  104  is urged outward in the vehicle widthwise direction by an urging force applied to the lid  24  by the first spring body  52 . In the present embodiment, the first spring body  52  which is realized as a coil spring is arranged in the first guide space S 2  defined in the lid  24  and is supported such that opposite end portions of the first spring body  52  are connected to the lid  24  and the first movable holder  104 . The first movable holder  104  is pressed outward in the vehicle widthwise direction by the first spring body  52  so as to be positioned at a predefined lid holding position. While the force is applied to displace the operating piece  50  inward in the vehicle widthwise direction against the first spring body  52 , the first movable holder  104  is displaced to a lid releasing position which is located inward in the vehicle widthwise direction with respect to the lid holding position. When the force no longer acts on the first operating piece  50 , the first movable holder  104  is returned to the lid holding position by the first spring body  52 . 
     Each of the first holding pieces  48  is a holding hook which protrudes downward from a bottom face of the lid  24 . Each first holding piece  48  has an L shape and includes a protruding part  48   a  extending downward from the coupling piece  102  and a hook part  48   b  extending in the vehicle widthwise direction from a lower end portion of the protruding part  48   a . The casing-side section  108  of the opening prevention part  42  includes a holding wall  112  in which openings  110  are defined. Each opening  110  of the holding wall  112  has a larger dimension in the vehicle widthwise direction than that of the hook part  48   b.    
     When the lid  24  closes the casing body  22  ( FIG. 9A ), the protruding parts  48   a  of the first holding pieces  48  of the first movable holder  104  extend through the openings  110  of the holding wall  112 , and the hook parts  48   b  are located below the holding wall  112 . When the first movable holder  104  is located at the lid holding position, the hook parts  48   b  are located so as to face a lower surface of the holding wall  112 . Thus, even if an attempt is made to move the rear end of the lid  24  upward with respect to the casing body  22 , the hook parts  48   b  are caught on the holding wall  112  to prevent the movement of the lid  24 , so that the casing body  22  is prevented from opening. 
     As described above, in conjunction with an operation of the first operating piece  50 , the first movable holder  104  can be moved inward in the vehicle widthwise direction against the urging force of the first spring body  52  ( FIG. 9B ). In this way, the first movable holder  104  can be moved from the lid holding position to the lid releasing position. When the first movable holder  104  is moved to the lid releasing position, the hook parts  48   b  are retracted away from the lower surface of the holding wall  112  to come into opening areas. 
     In this state, the hook parts  48   b  are no longer held on the holding wall  112 . In this state, the hook parts  48   b  can pass through the openings  110  of the holding wall  112  to move upward, without being held on the holding wall  112 . Accordingly, the first operating piece  50  can be operated with one hand, and the tab part can be operated with the other hand to move the rear end of the lid  24  upward with respect to the casing body  22 . In this way, the lid  24  is put into the openable-closable state. 
     With the lid  24  released from the casing body  22  and with the lid  24  opened, once the operator leaves the one hand operating the first operating piece  50 , the first movable holder  104  is moved outward in the vehicle widthwise direction due to the urging force of the first spring body  52  to return to the lid holding position ( FIG. 9C ). In this state, if the rear end portion of the lid  24  is moved downward in order to close the lid  24 , the hook parts  48   b  of the first movable holder  104  hit an upper surface of the holding wall  112 . In this case, when the hook parts  48   b  come into contact with the upper surface of the holding wall  112 , the downward movement of the lid  24  is prevented, so that the lid  24  is prevented from closing the casing body  22 . 
     In this case, both hands have to be used to close the casing body  22 , as with the opening operation of the casing body  22 . Specifically, in conjunction with an operation of the first operating piece  50  with one hand, the first movable holder  104  can be moved inward in the vehicle widthwise direction against the urging force of the first spring body  52 . In this way, the first movable holder  104  can be moved from the lid holding position to the lid releasing position. When the first movable holder  104  is moved to the lid releasing position, the hook parts  48   b  are retracted away from the lower surface of the holding wall  112  to come into the opening areas. 
     In this state, the hook parts  48   b  are no longer held on the holding wall  112 . In this state, the hook parts  48   b  can pass through the openings  110  of the holding wall  112  to move downward, without being held on the holding wall  112 . Accordingly, the first operating piece  50  can be operated with one hand, and the tab part can be operated with the other hand to move the rear end of the lid  24  downward with respect to the casing body  22 . 
     The casing body  22  ( FIG. 1 ) is removably attached to the vehicle body through an attaching-detaching holder  54  or attaching-detaching mechanism  54 . That is, the casing body  22  can be switched between a unremovable state and a removable state through the attaching-detaching holder  54 . The attaching-detaching holder  54  is located at an inner part of the pannier  14  in the vehicle widthwise direction. 
     Before describing the attaching-detaching holder  54 , a support structure of the pannier  14  will be described. As shown in  FIG. 4 , the second part  32  of the pannier stay  16  supports the first to-be-supported body  36  of the pannier  14 , and the third part  33  of the pannier stay  16  supports the second and third to-be-supported bodies  37 ,  38  of the pannier  14 . Specifically, the second part  32  of the pannier stay  16  is fitted into the first recess part  36   a  of the first to-be-supported body  36  of the pannier  14  from the front, and the third part  33  of the pannier stay  16  is fitted into the second and third recess parts  37   a ,  38   a  of the second and third to-be-supported bodies  37 ,  38  of the pannier  14  from below. 
     As shown in  FIG. 6A , a holder  55  is fixed to the pannier stay  16 . The holder  55  serves as a fixing part for preventing detachment of the pannier  14  from the pannier stay  16 . The holder  55  is fixed to the pannier stay  16  at a position adjacent to the third part  33  of the pannier stay  16 . In the present embodiment, the holder  55  is located close to a part of the pannier  14  where the third to-be-supported body  38  is fitted. Specifically, the holder  55  is located between the third part  33  and the connection of one of the support members  34  to the pannier stay  16 . In the present embodiment, the holder  55  is bolted to a fixing part on the pannier stay  16 . With the pannier  14  supported on the stay  16 , the holder  55  is located so as to face, from the front, a second holding member or second movable holder which will be described later. 
     As shown in  FIG. 7 , the holder  55  includes: a pipe insertion part  56  through which the pannier stay  16  is inserted; a supporting part  58  which projects downward from the pipe insertion part  56 ; and a holding part  60  which projects upward from the pipe insertion part  56 . The pipe insertion part  56  includes an insertion hole  56   a  through which the pannier stay  16  is inserted. The holding part  60  also includes a holding hole  60   a  which opens rearward. The later-described second holding piece  66  of the attaching-detaching holder  54  can be inserted into the holding hole  60   a.    
     The holder  55  serves to prevent attachment and detachment of the pannier  14  when the second holding piece  66  is inserted into the holder  55 . The holding part of the holder  55  is located above the pannier stay  16 . In other words, with the pannier  14  supported thereon, the holding part of the holder  55  is located above a support plane which is defined in the casing body  22 . The casing body  22  includes a fitting recess which receives the above-described holder  55  attached to the pannier stay  16 . The fitting recess is a recess which opens downward. The supporting part  58  includes a bolt insertion hole  58   a  facing the front-rear direction (i.e., the direction of extension of the third part  33 ). As shown in  FIG. 6A , on the other hand, an attaching piece  62  which protrudes downward is located on the third part  33  of the pannier stay  16 , and the attaching piece  62  includes a bolt insertion hole  62   a  facing the front-rear direction. With the third part  33  of the pannier stay  16  inserted through the pipe insertion part  56 , a fastener  64  such as a bolt is sequentially inserted, from a rear side of the vehicle body, into the bolt insertion hole  62   a  of the attaching piece  62  and the bolt insertion hole  58   a  of the supporting part  58  and is fastened with a nut  65 . Thus, the holder  55  is fixed at a predetermined position on the pannier stay  16 . 
     The attaching-detaching holder  54  is located at the inner part of the casing body  22  in the vehicle widthwise direction as described above. Specifically, the attaching-detaching holder  54  is located at an area between the storage space S 1  and an exterior member of the vehicle such as the rear frame  2  in a plan view of  FIG. 2 . Each of the casing body  22  and the lid  24  includes a defining wall which defines the storage space S 1  and a brim part which protrudes inward in the vehicle widthwise direction with respect to the defining wall. The attaching-detaching holder  54  is located in these brim parts. As shown in  FIG. 6A  and  FIG. 6B , the attaching-detaching holder  54  includes the second holding piece  66  or a second holding member or second movable holder  66 , a second operating member  68 , and a second spring body  70  ( FIG. 5 ). 
     The second operating member  68  is a rectangular slider which is partially exposed on an upper face of the lid  24 . The second operating member  68  can be freely moved in the front-rear direction when an operator pinches and slides the second operating member. Specifically, the second operating member  68  is supported by the lid-side brim part  120  ( FIG. 4 ) which protrudes inward in the vehicle widthwise direction with respect to the defining wall which defines the storage space S 1  in the lid  24 . 
     The second operating member  68  is housed in a second guide space S 3  defined in the lid-side brim part  120  and is guided in a displaceable manner in the front-rear direction within a predefined allowable range. In other words, the second operating member  68  is housed in the second guide space S 3  of the lid  24 , so that the second operating member is prevented from being displaced in other directions than the front-rear direction. The second operating member  68  includes an operating piece  68   a  which is exposed above the lid-side brim part  120 , and a protruding piece  68   b  which is connected to the operating piece  68   a  and protrudes downward from the lid-side brim part  120 . 
     The second movable holder  66  is located below the second operating member  68 . Specifically, the second movable holder  66  is supported by the body-side brim part  63  ( FIG. 1 ) which protrudes inward in the vehicle widthwise direction with respect to the defining wall which defines the storage space S 1  in the casing body  22 . The second movable holder  66  is housed in a third guide space S 4  defined in the body-side brim part  63  and is guided in a displaceable manner in the front-rear direction within a predefined allowable range. In other words, the second movable holder  66  is housed in the third guide space S 4  of the casing body  22 , so that the second movable holder is prevented from being displaced in other directions than the front-rear direction. When the casing body  22  is attached to the pannier stay  16 , the third guide space S 4  is located adjacent to the holder  55 . That is, the fitting recess (not illustrated) which receives the holder  55  is located in the casing-side brim part  63  of the casing body  22 . 
     The casing-side brim part  63  includes a communication hole (not illustrated) which communicates the third guide space S 4  with the fitting recess in the front-rear direction. The casing body  22  includes a wall facing the holder  55  from the rear when the holder  55  is fitted into the fitting recess. Thus, when the holder  55  is fitted into the fitting recess, the casing body  22  is prevented from moving forward with respect to the pannier stay  16 . 
     The second movable holder  66  includes a groove part  67  which is exposed above the body-side brim part  63 . The groove part  67  includes an engagement groove  66   a  which can be engaged with the protruding piece  68   b  of the second operating member  68 . Specifically, the groove part  67  includes a front side surface which faces the engagement groove  66   a  on the front side and a rear side surface which faces the engagement groove  66   a  on the rear side. The dimension between the front side surface and the rear side surface in the front-rear direction is slightly larger than the dimension of the protruding piece  68   b  in the front-rear direction. At least one of the front side surface and the rear side surface includes, at an upper part thereof, an inclined surface which is inclined away from the engagement groove  66   a  in the front-rear direction as it extends upward. 
     When the lid  24  is closed ( FIG. 6A ), the protruding piece  68   b  of the second operating member  68  is located at a position where the protruding piece  68   b  is engaged with the engagement groove  66   a  of the second movable holder  66 . The engaged second movable holder  66  moves in the front-rear direction in conjunction with the second operating member  68 . The second movable holder  66  and the second operating member  68  may be integrated with each other. Alternatively, the second operating member  68  may include a groove on a lower face thereof, and the second movable holder  66  may include an engagement protrusion on an upper face thereof. 
     The second movable holder  66  includes a front end portion which is connected to the groove part and extends frontward from the groove part and a rear end portion which extends rearward from the groove part. The front end portion of the second movable holder  66  penetrates through the communication hole so as to be able to move into and out of the fitting recess. When the pannier  14  is attached to the pannier stay  16 , the front end portion of the second movable holder  66  is fitted into the holding hole  60   a  of the holder  55 . The holder  55  faces at least the front end portion of the second movable holder  66  from above. Thus, the casing body  22  is held by the holder  55 , so that the casing body  22  is prevented from moving upward with respect to the pannier stay  16 . 
     At least one of the second operating member  68  and the second movable holder  66  receives a frontward urging force given by the second spring body  70 . In the present embodiment, the second operating member  68  receives a frontward urging force given by the second spring body  70 . Specifically, the second spring body  70  which is realized as a coil spring is arranged in the storage space defined in the lid-side brim part  120  and is supported such that one end portion of the second spring body  70  is connected to the lid  24 , and the other end portion of the second spring body  70  is connected to the second operating member  68 . The second operating member  68  is pressed frontward by the second spring body  70 . 
     As described above, when the lid  24  is closed, the second operating member  68  is kept in a held state with the second movable holder  66 . Thus, as with the second operating member  68 , the second movable holder  66  is also pressed forward. Accordingly, when no force acting against a spring force of the second spring body  70  is applied to the second operating member  68 , the front end portion of the second movable holder  68  is held in conjunction with the holder  55  and the pannier stay  16 , and the casing body  22  is maintained in the unremovable state with respect to the vehicle body. Specifically, the holding piece  66  prevents the casing body  22  from moving upward with respect to the pannier stay  16 . In addition, the holder  55  prevents the casing body  22  from moving rearward with respect to the pannier stay  16 . Further, the holder  55  and the pannier stay  16  prevent the casing body  22  from moving in the vehicle widthwise direction and downward with respect to the pannier stay  16 . 
     When the lid  24  is closed, if an operator slides the second operating member  68  rearward ( FIG. 6B ), the second movable holder  66  is moved rearward with respect to the casing body  22  in conjunction with the second operating member  68 . Thus, the front end portion of the second movable holder  68  is withdrawn from the holding hole  60   a  of the holder  55  to dissociate the second movable holder  68  and the holder  55 . In this state, since the front end portion of the second movable holder  68  is withdrawn rearward from the holding hole  60   a  of the holder  55 , the holder  55  can avoid interfering the upward movement of the casing body  22 . Thus, the casing body  22  can be moved upward with respect to the pannier stay  16 . When the casing body  22  is moved upward with respect to the pannier stay  16  and the holder  55  is no longer fitted in the fitting recess, the casing body  22  can be detached from the pannier stay  16 . 
     The opening-closing holder (opening prevention part)  42  and the attaching-detaching holder  54  in  FIG. 5  can be locked. That is, the opening-closing holder  42  can be locked in a closed state (i.e., an unopenable-unclosable state), and the attaching-detaching holder  54  can be locked at a held position (i.e., an unremovable state). The pannier  14  includes the cylinder  69  which serves to lock both of the attaching-detaching holder  54  and the opening-closing holder  42 . This means that the single cylinder  69  can be used to lock and unlock the pannier  14  for attachment to and detachment from the vehicle body as well as the lid  24  of the pannier  14  for opening and closing. In the present embodiment, the cylinder  69  can be angularly displaced between a lock position and an unlock position; at the lock position, the unopenable-unclosable state and the unremovable state are attained, whereas at the unlock position, the openable-closable state and the removable state are attained. 
     In the present embodiment, the cylinder  69  is a key cylinder which can be locked and unlocked by inserting and turning a key. The cylinder  69  has an axis AX extending in the vertical direction and includes an exposed upper face. The cylinder  69  partially overlaps with the pannier stay  16  when viewed in the axial direction (i.e. the vertical direction). The cylinder  69  includes, on the upper face thereof, a keyhole  69   a  into which a key is inserted as shown in  FIG. 4 . The cylinder  69  is turnably supported by the lid  24 . That is, the cylinder  69  is relatively movable in conjunction with the lid  24  with respect to the casing body  22 . The part of the cylinder  69  other than the keyhole  69   a  is covered by a cover  76  which is a part of the lid  24  and covers a peripheral surface of the part other than the keyhole  69   a  from an upper side, a rear side and an inner side in the vehicle widthwise direction. In the present embodiment, the cylinder  69  has an internal structure such that when the key is inserted in the keyhole  69   a , the key cannot be removed unless the cylinder  69  is at the lock position. 
     When the pannier  14  is attached to the pannier stay  16 , the cylinder  69  is disposed in an area between the vehicle body frame FR and the storage space S 1  in a planar view. Specifically, the lid-side brim part which is located at an inner portion of the rear part of the lid  24  in the vehicle widthwise direction includes a cylinder housing part  71 , and this cylinder housing part  71  houses the cylinder  69 . The above-described first movable holder and second movable holder ( FIG. 6A ) are also housed in a space defined within the lid  24 . In the present embodiment, the cylinder  69  is arranged adjacent to the third to-be-supported body  38  of the casing body  22 . 
     The cylinder  69  is arranged adjacent to an inner end portion of the first movable holder  104  in the vehicle widthwise direction and to the rear end portion of the second movable holder  68 . The cylinder  69  includes locking pieces  72 ,  74  which are arranged so as to prevent movement of the first movable holder  104  and the second movable holder  68  located adjacent to the respective locking pieces  72 ,  74 , when the cylinder  69  is moved to the lock position. When the cylinder  69  is moved to the unlock position, the locking pieces  72 ,  74  are moved to retracted positions with respect to the respective movable holders  104 ,  68 . Thus, the locking pieces  72 ,  74  are released so as not to prevent the movement, so that the respective movable holders  104 ,  68  are allowed to move. 
     As shown in  FIG. 5 , the first locking piece  72  and the second locking piece  74  are located on an outer periphery of the cylinder  69 . The first locking piece  72  when at the lock position prevents the first operating member  50  from moving inward in the vehicle widthwise direction. In the present embodiment, the first locking piece  72  is held in a recess (not illustrated) in the first operating member (first operating piece)  50  to prevent the first operating piece  50  from moving in the vehicle widthwise direction. 
     Specifically, the lock mechanism includes a cam member  114  which operates in conjunction with the cylinder  69  as shown in  FIG. 10A  and  FIG. 10B . The cylinder  69  includes a protrusion  116  which serves as the first locking piece  72  at a radially outer part of the cylinder  69  with respect to the center of rotation. The cam member  114  includes an elongated hole  114   a  which receives the protrusion  116  on the cylinder  69 . The cam member  114  is housed in the lid  24 , so that the movement direction of the cam member  114  is directed to the front-rear direction. 
     The cam member  114  is connected to the protrusion  116  of the cylinder  69 , so that the cam member  114  is moved in the front-rear direction in association with the angular displacement of the protrusion  116 . When the cylinder  69  is moved to the lock position ( FIG. 10B ), the cam member  114  is pushed rearward by the protrusion  116  to hold the first movable holder  104  located at the lid holding position. Specifically, a tip end portion of the cam member  114  is fitted into a groove (recess)  106  in the first movable holder  104  so as to prevent the first movable holder  104  from moving in the vehicle widthwise direction. Thus, at the lock position, even if an attempt is made to move the first operating piece  50  in the vehicle widthwise direction, the first locking piece  72  prevents the first operating piece  50  from moving in the vehicle widthwise direction, so that a third party who does not have the key cannot open the lid  24 . 
     When the cylinder  69  is moved to the unlock position with the key ( FIG. 10A ), the cam member  114  is pushed back frontward in association with the angular displacement of the protrusion  116  so as to dissociate the first movable holder  104  and the cam member  114 . In this state, an operator can apply a force to the first operating piece  50  against the urging force by the first spring body  52  to move the first movable holder  104  inward in the vehicle widthwise direction. 
     The second locking piece  74  when at the lock position prevents the second movable holder  66  from moving in the front-rear direction ( FIG. 10B ). Specifically, the second locking piece  74  is located at a lower end portion of the cylinder  69 . When the lid  24  is closed, the second locking piece  74  is located at a same height as a rear end face of the second movable holder  66 . In addition, the second locking piece  74  protrudes radially outward with respect to the rest part of the cylinder. 
     When the cylinder  69  is moved to the lock position, the second locking piece  74  faces the rear end face of the second movable holder  66  from the rear to prevent the second movable holder  66  from moving rearward. This makes it possible to prevent the movement of the second movable holder  66  from the casing fixing position and thus to prevent attachment and detachment of the pannier  14 . Since the second operating member  68  and the second movable holder  66  are held to each other when the lid  24  is closed, at the lock position, even if an attempt is made to move the second operating member  68  rearward, the second locking piece  74  prevents the second holding piece  66  from moving rearward, so that a third party who does not have the key cannot detach the pannier  14  from the vehicle body. 
     When the cylinder  69  is moved to the unlock position with the key ( FIG. 10A ), the second locking piece  74  is angularly displaced so as not to face the second movable holder  66 . In other words, a gap is generated between the second movable holder  66  and the cylinder  69 , so that the second movable holder  66  can be moved rearward. In this state, an operator can apply a force to the second operating member  66  against the urging force by the second spring body  70  to move the second movable holder  66  rearward. 
     Thus, when the cylinder  69  is turned from the lock position to the unlock position, the first locking piece  72  which serves as the cam member is disengaged from the first movable holder  50 , so that the first operating member  50  can be moved in the vehicle widthwise direction when the lid  24  is in the closed state. Therefore, at the pannier opening position, the first operating member  50  is moved outward in the vehicle widthwise direction (to a position indicated with a double dotted line) to move the first holding pieces  48  in the vehicle widthwise direction. Thus, the lid  24  can be opened. 
     When the cylinder  69  is turned from the lock position to the unlock position, the second locking piece  74  is disengaged from the second movable holder  66 , so that the second movable holder  66  can be moved rearward when the pannier  14  is in the unremovable state. Therefore, at the pannier detaching position, the second operating member  68  is moved rearward to move the second movable holder  66  rearward. Thus, the pannier  14  can be removed from the vehicle body. 
     In the present embodiment, the pannier detaching position and the pannier opening position of the cylinder  69  are located at a same position in a turning direction. Alternatively, these positions may be different. For example, the pannier opening position may be located at a position angularly displaced from the lock position by a predetermined angle, and the attaching-detaching position may be located at a position where the cylinder  69  is angularly displaced from the pannier opening position. Further, in the present embodiment, the axial direction of the cylinder  69  corresponds to the vertical direction of the vehicle. However, the axial direction is not limited to the vertical direction and may correspond to, for example, the vehicle widthwise direction or the front-rear direction of the vehicle. 
     As described above, at the lock position, the second movable holder  66  and the first holding pieces  48  are fixed at positions where the casing body  22  cannot be removed from the vehicle body, and the lid  24  cannot be opened with respect to the casing body  22 . At the pannier detaching position, the second movable holder  66  can be moved to a position where the casing body  22  can be removed from the vehicle body. Further, at the pannier opening position, the first holding pieces  48  can be moved to a position where the lid  24  can be opened with respect to the casing body  22 . 
     When the cylinder  69  is at the lock position, the first holding pieces  48  come into contact with the holding wall  112  on the casing side, so that the lid  24  is prevented from closing. This allows an operator to determine that the lid  24  is not closed with the cylinder  69  at the lock position. In this way, a user is encouraged to perform a lock operation when the lid  24  is closed. This makes it possible to prevent the lid  24  from opening unintentionally and to prevent the pannier  14  from detaching unintentionally from the vehicle body. 
     The pannier  14  according to the present embodiment includes indicators (warning indicators)  75 A,  75 B which indicates when the second movable holder  66  is not at the lock position. The indicator  75 A is located on an upper face of the second operating member  68  ( FIG. 8B ), and the indicator  75 B is located in a movement area for the second operating member  68  on an upper face of the lid  24  ( FIG. 8C ). Specifically, the indicator  75 A is located at a rear half of the upper face of the second operating member  68 , and the indicator  75 B is located at a rear part of the movement area for the second operating member  68  on the upper face of the lid  24 . In the present embodiment, the indicators  75 A,  75 B are red marks on the upper face of the second operating member  68  and the upper face of the lid  24 . However, the indicator  75 A,  75 B are not limited to red marks. 
     When the second operating member  68  is moved in the front-rear direction, the rear half of the second operating member  68  is moved into and out of the cover  76 . That is, as indicated by a double dotted line  300  in  FIG. 6A , when the second movable holder  66  is not at the lock position, the second holding piece  66  is moved frontward by the urging force of the second spring body  70 , and the indicator  75 A on the upper face of the second operating member  68  is exposed so as to be visible as shown in  FIG. 8B . As indicated by a double dotted line  200  in  FIG. 6A , when the second holding piece  66  is caught by the holder  55  and thus cannot be held in the holding hole  60   a , the second holding piece  66  is moved rearward, and the indicator  75 B on the upper face of the cylinder housing part  71  is exposed so as to be visible as shown in  FIG. 8C . 
     As indicated with a solid line in  FIG. 6A , on the other hand, when the second movable holder  66  is at the lock position, the second movable holder  66  is held and retained in the holding hole  60   a  of the holder  55 , so that the indicators  75 A,  75 B are not exposed as shown in  FIG. 8A . This makes it easy to visually know that the pannier  14  is attached to the vehicle body. Alternatively, it is possible to provide either the indicator  75 A on the upper face of the second operating member  68  or the indicator  75 B on the upper face of the lid  24  only. Further, the indicators  75 A,  75 B may be omitted. 
     The effects of the pannier  14  according to the present embodiment will be described. To remove the pannier  14  shown in  FIG. 2  from the vehicle body or to open the lid  24  of the pannier  14 , the key is inserted into the keyhole  69   a  of the cylinder  69  and is turned in a rotation direction R 1 . In the present case, the key(s) is(are) turned in the same rotation direction R 1  in both the left and right panniers  14 . Since the cylinders  69  are located at the rear end portions of the panniers  14 , key operations would be performed from the rear of the vehicle body. This configuration provides good handleability because the key operations can be performed in the same direction for both the left and right panniers  14 . However, the left and right pannier  14  may have different turning directions for the key(s). 
     When the cylinder  69  is turned in the rotation direction R 1 , the cylinder  69  is moved from the lock position to the pannier detaching position and the pannier opening position. Thus allows the pannier  14  to be removed from the vehicle body and allows the lid  24  to be opened. At the pannier opening position, the first operating member  50  can be moved inward in the vehicle widthwise direction. Since the first operating member  50  is located on a rear face of the pannier  14  and the lid  24  is opened from the rear to the front, it is easy to open and close the lid  24  from the rear of the vehicle body. This provides good handleability starting from a key operation to an opening/closing operation of the lid  24 . 
     At the pannier detaching position, the second operating member  68  can be moved rearward. Since the second operating member  68  is located at the rear part of the pannier  14  and the handle  30  is located at the rear face of the pannier  14 , it is easy to perform a detaching operation of the pannier  14  from the rear. Thus, in the present embodiment, it is easy to perform all of a key operation, an opening/closing operation of the lid  24 , and a detaching operation of the pannier  14  from the rear, so that good handleability is achieved. 
     Where the top casing  20  is disposed, a lid of the top casing  20  may also be constructed to be opened from the rear to the front, so that all of the panniers  14  and the top casing  20  can be operated from the rear, which further enhances handleability. 
     According to the above constitution, it is possible to lock and unlock the pannier  14  for attachment to and detachment from the vehicle body as well as the lid  24  for opening and closing through a turning operation of each cylinder  69  as shown in  FIG. 2 . Therefore, as compared with a case where the pannier  14  includes separate lock structures for these operations, the pannier  14  includes a reduced number of components and have improved handleability. 
     Further, thanks to the indicators  75 A,  75 B which indicate when the cylinder  69  is not at the lock position as shown in  FIG. 8B  and  FIG. 8C , it is possible to visually know the lock state of the attaching-detaching holder  54 . Thus, it is possible to prevent a driver from driving the vehicle with the attaching-detaching holder unlocked. 
     When the lid  24  is open with respect to the casing body  22  and the cylinder  69  is at the lock position, the opening prevention part  42  is in contact with the cylinder  69  to prevent the lid  24  from closing. Thus, if the lid  24  cannot be closed, a user would be more likely to notice that the cylinder  69  is at the lock position with the lid  24  open, so that the user is encouraged to perform a lock operation with the lid  24  closed. 
     The cylinder  69  and the holder  55  as shown in  FIG. 6A  are disposed adjacent to the third to-be-supported body  38 . Thus, there is a smaller distance between the second movable holder  66  and the third to-be-supported body  38 , which can prevent increase in the size of the holding piece  66 . 
     The second movable holder  66  and the cylinder  69  are disposed in an area between the rear frame  2  and the storage space S 1  as shown in a plan view of  FIG. 2 . Thus, the second movable holder  66  and the cylinder  69  are disposed on the inner side in the vehicle widthwise direction with respect to the casing body  22 , so that it is possible to prevent damage to the second movable holder  66  and the cylinder  69  when the vehicle body is overturned. 
     As shown in  FIG. 6A , the second movable holder  66  and the cylinder  69  are located within the cylinder housing part  71  in the lid  24 . In such a case where the second movable holder  66  and the cylinder  69  are located in the lid  24 , it is easier to arrange them at peripherally exposed positions in the pannier  14  than in a case where they are located in the casing body  22 . This provides easier access to the cylinder  69  and provides good handleability. 
     Further, there is the second operating member  68  which moves the second movable holder  66 . Therefore, a driver can use the second operating member  68  to move the second movable holder  66 , which enhances handleability when the pannier  14  is attached to and detached from the vehicle body. 
     Since the lid  24  as shown in  FIG. 2  is constructed to be opened from the rear to the front when mounted on the vehicle body, the lid  24  is unlikely to open during driving. Further, since the handle  30  is located on the rear face of the casing body  22 , it is easy to perform an opening/closing operation of the lid  24  and a detaching operation of the pannier  14  from the rear of the vehicle body, so that good handleability is achieved. This also makes it possible to restrain an opening/closing operation of the lid  24  by a driver while driving. 
     The cylinder  69  as shown in  FIG. 6A  has the axis AX extending in the vertical direction and includes the exposed upper face. The cylinder  69  partially overlaps with the pannier stay  16  when viewed in the axial direction. Thus, the cylinder  69  is arranged above the pannier stay  16 , so that it is possible to prevent reduction of the storage space S 1  due to the cylinder  69  and suppress increase in the dimension in the vehicle widthwise direction. 
     Since the handle  30  is located at a position adjacent to the cylinder  69  and the second operating member  68 , an unlock operation of the pannier  14  and a transport operation of the pannier  14  using the handle  30  can be more easily performed, so that convenience is improved. The handle  30  can be used to transport the pannier  14  and to move the pannier  14  when the pannier  14  is attached to or detached from the pannier stay  16 , so that the structure can be simplified as compared with a case where the pannier  14  includes separate handles  30  for these operations. 
     Since the tab part is arranged at a position adjacent to the cylinder  69  and the first operating piece  50 , an unlock operation of the lid  24  and an opening/closing operation of the lid  24  using the tab part can be more easily performed. Further, since the handle  30  of the casing body  22  and the tab part of the lid  24  are vertically arranged, a transport operation of the pannier  14  and an opening/closing operation of the lid  24  can be more easily performed. 
     The respective operating pieces  50 ,  68  and the cylinder  69  are arranged on the inner side in the vehicle widthwise direction in the pannier  14 . Thus, even if the vehicle comes close to or into contact with an obstacle, the operating pieces  50 ,  68  can be prevented from coming into contact with the obstacle, so that the operating pieces  50 ,  68  are more likely to be protected against damage. 
     Since the cylinder  69  is constructed such that the key cannot be inserted or removed unless the cylinder  69  is at the lock position, the cylinder  69  is prevented from being kept at the unlock position when the key is removed. Thus, when the key is removed from the cylinder  69 , the cylinder  69  is necessarily put into the lock state, so that antitheft performance is improved. Since the holder  55  and the cylinder  69  are arranged at adjacent positions, the second movable holder  66  can be prevented from having an increased size. 
     Since the lid-side brim part is arranged above the pannier stay  16  in an overlapping manner, it is possible to prevent increase in the size of the pannier  14  in the vehicle widthwise direction, as compared with a case where the pannier stay  16 , the cylinder  69  and the like are arranged next to one another in the vehicle widthwise direction. 
     Since the first operating piece  50 , the second operating piece  68  and the cylinder  69  are located in the lid, they can be arranged at higher positions than those in a case where they are located in the casing body, so that an operator can more easily perform an operation. Since the cylinder  69  is located in the lid, it is possible to hinder a lock/unlock operation while the lid is open. 
     Since the various mechanisms are arranged outside the storage space S 1 , there is less unevenness inside the storage space S 1 , so that an item can be smoothly taken out from the storage space. Since the first movable holder  104  and the second movable holder  66  are arranged outside the storage space S 1  and in a space walled off from the storage space S 1 , it is possible to avoid contact between an item(s) and the respective movable holders  104 ,  66  to prevent the item(s) from interfering the movement of the movable holders  104 ,  66 . 
     In the present disclosure, the movable holder may further include a warning indicator which indicates when the movable holder is at the attachable-detachable position. According to this constitution, it is possible to visually know the state of the movable holder. Thus, a user can visually see the warning indicator to know that the pannier is not secured in an unremovable manner. By allowing the user to know such a warning, it is possible to prevent the user from driving the vehicle when the movable holder is at the attachable-detachable position, and thus to prevent detachment of the pannier while driving. 
     In the present disclosure, the pannier may include a preventer which is in contact with the cylinder to prevent the lid from closing when the lid is open with respect to the casing body and the cylinder is at the lock position. According to this constitution, if the lid cannot be closed, a user would be more likely to notice that the cylinder is at the lock position with the lid open, so that the user is encouraged to perform a lock operation with the lid closed. 
     In the present disclosure, the casing body may include a to-be-supported body to be supported on the vehicle body, and the cylinder may be arranged adjacent to the to-be-supported body. According to this constitution, there is a smaller distance between the cylinder and the to-be-supported body, which can prevent increase in the size of the movable holder interposed between the cylinder and the to-be-supported body. 
     In the present disclosure, the cylinder may be arranged in an area closer to the vehicle than the storage space for the item is to the vehicle when the pannier is attached to the vehicle. According to this constitution, the cylinder is located on the inner side in the vehicle widthwise direction with respect to the lid, so that it is possible to prevent the cylinder from being damaged when the vehicle body is overturned. 
     In this case, the cylinder may be disposed within a cylinder housing part in the lid. According to this constitution, since the cylinder is disposed in the lid, the cylinder can be arranged at a more accessible position for a user than that in a case where the cylinder is disposed in the casing body, so that handleability is improved. 
     In the present disclosure, the pannier may include an operation piece which is operable by an operator to move the holding piece. According to this constitution, an operator can move the holding piece with the operation piece to undo the lock. This necessitates an operation by an operator in order to undo the lock, so that it is possible to prevent unintentional unlocking. 
     In the present disclosure, the lid may be constructed to open from the rear to the front when the pannier is attached to the vehicle, and the casing body may include a handle on a rear face of the casing body. According to this constitution, since the lid is constructed to open from the rear to the front, the lid is unlikely to open during driving. Further, an opening/closing operation of the lid and a detaching operation of the pannier can be performed from the rear of the vehicle, which provides good handleability. 
     A vehicle according to the present disclosure includes: the pannier according to the present disclosure; a vehicle frame; and a pannier stay which supports the casing body on the vehicle frame, wherein the cylinder has an axis extending in a vertical direction and includes an upper face exposed from the lid, and the cylinder partially overlaps with the pannier stay when viewed in a direction of the axis. According to this constitution, since the cylinder is located above the stay, it is possible to prevent reduction of the storage space due to the cylinder and suppress increase in the dimension in the vehicle widthwise direction of the vehicle as a whole including the pannier. 
     The present disclosure is not limited to the above embodiment, various additions, modifications, or deletions may be made without departing from the scope of the disclosure. The first movable holder  104  and the second movable holder  66  may be a single member. For example, the first movable holder  104  may be located on an inner side of the pannier  14  in the vehicle widthwise direction and be integrated with the second operating member  68 . The pannier may have a structure in which a single operating piece is used to perform an operation to attain the attachable-detachable state and the openable-closable state. Thus, the number of components can further be reduced. 
     In addition to indicating a warning when the cylinder is not at the lock position, the indicator  75  may indicate when the cylinder is at the lock position. The keyhole  69   a  may be located away from the cylinder  69 . In such a case, there should be a first cylinder which includes the keyhole  69   a  as well as a turning force transmission mechanism (such as a cable) which transmits a turning force from the first cylinder to a second cylinder for the lock of the holding piece. The cylinder  69  may be arranged at a front end of the pannier  14  and on the inner side in the vehicle widthwise direction. In this case, the first movable holder  104  and the second movable holder  66  should also be located on the front side of the pannier  14 . 
     If the first movable holder is located opposite from the hinge  40 , the lid  24  can be more easily prevented from opening. Where the second operating member  68  is located in the lid, and the second movable holder  66  is located in the casing, it is possible to achieve both handleability and strength when the pannier is mounted. Further, if the entire first movable holder except for the operation part is received in the lid  24 , it is possible to prevent an item or an obstacle from interfering with the movement of the movable holder. 
     The pannier  14  is expected to be mounted at an outwardly exposed position on the vehicle. Thus, a user can access the pannier from a position around the vehicle to take out an item within the pannier  14  and detach the pannier  14  from the vehicle to transport the whole pannier  14  including the item(s). The vehicle according to the above embodiment is a mere example, and the present disclosure may be applied to any vehicle other than a motorcycle. For example, the vehicle may be a saddle-riding vehicle such as a motorcycle and a three-wheeler, a convertible without a body which covers a vehicle inner space, or a service vehicle. 
     The pannier  14  according to the above embodiment is described with reference to a case where the pannier is disposed on each of the left and right sides of the vehicle. The present disclosure also includes a case where the pannier is disposed on only one side of the vehicle. The present disclosure further includes a case where the pannier is disposed at a position other than the left and right sides, such as at an upper position of the vehicle.
