Title: Baggage compartment structure of vehicle

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a baggage compartment structure of a vehicle, which comprises a trunk room which is provided at a rear portion of a vehicle body so that an opening formed at an upper face thereof is configured to be closed with a trunk lid. 
     For example, a sedan type of vehicle or a sports car type of vehicle have the trunk room which is provided at the rear portion of the vehicle body so that the opening formed at the upper face thereof can be closed with the trunk lid. In these types of vehicle, there is a case in which the size of the trunk room (volume, length, width, depth, etc.) may not be made large enough to store a large-sized baggage from a design or vehicle size perspective, for example. Meanwhile, the utility function of loading the large-sized baggage, such as a bicycle, has been recently demanded to even these types of vehicle for leisure or the like. 
     Japanese Patent Laid-Open Publication No. 11-245735, for example, discloses a baggage loading structure of the above-described type of vehicle, in which there are provided a pair of right and left rails and a support member for these rails are provided from a vehicle roof to an upper portion of a vehicle-body rear portion so as to load a bicycle as a large-sized baggage. Herein, a truck may be prepared so as to move on the rails by holding the bicycle on it, so that the bicycle can be properly loaded on the vehicle roof. 
     According to the baggage loading structure disclosed in the above-described patent publication, the truck may be necessary in addition to providing the rails provided from the vehicle roof to the upper portion of the vehicle-body rear portion, so the structure would become rather large and complex. Further, the truck may be designed only for the bicycle, so that another truck may be necessary for loading another kind of baggage. 
     Further, while the above-described patent document contains the description that the rails may be provided detachably, since the structure is rather large and complex as described above, attachment or detachment of the rails may require a considerably long time. Thus, the rails may be considered as parts which are substantially attached all the time. Therefore, the vehicle design may be damaged improperly. 
     Other baggage loading strictures which are similar to the above-described structure are also disclosed in Japanese Patent Laid-Open Publication Nos. 07-215136 and 2003-137035. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a baggage compartment structure of a vehicle which comprises a trunk room which is provided at a rear portion of a vehicle body so that an opening formed at an upper face thereof is configured to be closed with a trunk lid, which can properly load various types of large-sized baggage without having the large and complex structure and damaging the vehicle design improperly. 
     According to the present invention, there is provided a baggage compartment structure of a vehicle, which comprises a trunk room which is provided at a rear portion of a vehicle body so that an opening formed at an upper face thereof is configured to be closed with a trunk lid, wherein the trunk lid is provided so as to rotate around a front end portion thereof in such a manner that a back face thereof in an open state faces substantially upward and there is provided a support means operative to support the trunk lid in the open state. 
     According to the above-described present invention, by rotating the trunk lid around its front end portion in such a manner that the back face of the trunk lid in the open state faces substantially upward and by supporting the trunk lid, the baggage can be loaded by using the space inside and above the trunk room. For example, a baggage with the height which is greater than the depth of the trunk room or a baggage, such as a plant, having an upper portion with the longitudinal width which is greater than the opening of the trunk room can be loaded properly. Further, if a baggage fixing means, which will be described below, is used, a baggage like the bicycle can be loaded by using the space above the trunk lid and the opening of the trunk room. That is, the various types of large-sized baggage can be properly loaded without having the large and complex structure and damaging the vehicle design improperly. Further, since the trunk lid is supported by the support means in its open state, the trunk lid can be properly prevented from fluttering due to the vehicle vibration and thereby any improper influence to the vehicle body may be prevented. 
     According to an embodiment of the present invention, a baggage fixing means operative to fix a baggage in such a manner that a space above the trunk lid which is positioned in a specified open state and the opening of the trunk room is used as a loading space of the baggage fixed is fixedly or detachably provided at a specified position which enables the baggage fixing means to be located inside the trunk room when the opening of the trunk room is closed with the trunk lid. Thereby, since the baggage fixing means is provided so as to fix the baggage in such a manner that the space above the trunk lid and the opening of the trunk room is used as the loading space of the baggage fixed, the large-scaled baggage like the bicycle or a surfboard can be loaded by using the space above the trunk lid and the opening of the trunk room. Herein, since the baggage fixing means is fixedly or detachably provided at the specified position which enables the baggage fixing means to be located inside the trunk room when the opening of the trunk room is closed with the trunk lid, it is not viewed from the outside of the vehicle when the trunk lid is closed. Accordingly, the fine view of the vehicle may not deteriorate. Further, in a case in which the baggage fixing means is detachably provided, the space inside the trunk room can be properly used by removing the baggage fixing means when the trunk lid is closed. Also, various types of fixing means may be applied, and various types of baggage may be loaded accordingly. 
     According to another embodiment of the present invention, the vehicle is an open-top type of vehicle, in which an upper portion above a vehicle compartment which is formed in front of the trunk room is configured to be opened, and the support means is configured to support the trunk lid in such a manner that an upper end of the trunk lid in the open state is positioned at a specified level which is higher than an upper end of a passenger with a specified size who is seated at a specified location in the vehicle compartment. Thereby, even if any loaded article jumps out of the trunk room when the vehicle has a rear collision in a state in which the trunk lid is open, the trunk lid may protect the passenger of the vehicle from the article jumping out. 
     According to another embodiment of the present invention, the vehicle is an open-top type of vehicle, in which an upper portion above a vehicle compartment which is formed in front of the trunk room is configured to be opened, and the trunk lid in the open state is configured to constitute an aero-board operative to restrain a traveling wind (air) from flowing into a vehicle compartment. Thereby, the traveling wind (air) can be properly prevented from flowing into the vehicle compartment. 
     According to another embodiment of the present invention, the vehicle is an open-top type of vehicle, in which an upper portion above a vehicle compartment which is formed in front of the trunk room is configured to be opened, a roll bar is provided between the vehicle compartment and the trunk lid, and an interference-preventing portion operative to prevent interference of the trunk lid in the open state with the roll bar is provided at the trunk lid. Thereby, the trunk lid can be properly opened to its open state without any interference with the roll bar. 
     According to another embodiment of the present invention, a storage portion of the trunk room is comprised of a watertight storage-container member with water-resisting qualities. Thereby, even if the vehicle travels with the trunk lid open when it rains, the rain can stay properly in the storage-container member. Accordingly, the inside of the trunk room or panels which form the inner face of the vehicle body can be properly protected from the rainwater. 
     According to another embodiment of the present invention, a drain member to drain a liquid staying in the storage-container member is provided at the storage-container member. Thereby, the rainwater or the like which stay in the storage-container member can be drained easily. Herein, if the storage-container member is provided detachably to the trunk room, the liquid staying in it can be drained outside the trunk room. 
     According to another embodiment of the present invention, the storage-container member is so deep that a bottom thereof is located close to a lower face portion of the vehicle body. Thereby, the tall baggage can be stored stably without its projecting upward improperly. 
     According to another embodiment of the present invention, a lid to partition an inside space of the storage-container member into an upper side and a bottom side is provided at the storage-container member. Thereby, any thing which requires its privacy may be stored in the space of the bottom side of the storage-container member below the lid, so that the thing can be prevented from being viewed from the outside by the lid even when the trunk lid is open, thereby protecting the privacy of the thing. Further, articles stored in the space of the bottom side of the storage-container member can be prevented from being scattered in the air while the vehicle travels with the trunk lid open. 
     According to another embodiment of the present invention, a space to store a baggage therein is provided at a front portion of the storage-container member, and a lid to partition the space from an inside space of the storage-container member is provided at the storage-container member. Thereby, any thing which requires its privacy may be stored in the space at the front portion of the storage-container member, so that the thing can be prevented from being viewed from the outside by the lid even when the trunk lid is open, thereby protecting the privacy of the thing. Further, articles stored in the space at the front portion of the storage-container member can be prevented from being scattered in the air while the vehicle travels with the trunk lid open. 
     According to another embodiment of the present invention, at the storage-container member is provided a deformation promoting means operative to promote deformation of the storage-container member substantially in a longitudinal direction of the vehicle body when a specified load is applied to the storage-container member substantially in the longitudinal direction of the vehicle body. Thereby, it can be properly restrained that the impact load is applied to the vehicle compartment which is provided in front of the trunk room at the vehicle rear collision or the like. Accordingly, the safety of the passenger in the vehicle compartment can be improved. 
     According to another embodiment of the present invention, the storage-container member is made from resin. Thereby, the control of the above-described specified load can be easily conducted by adjusting the thickness or the like of the resin member. 
     According to another embodiment of the present invention, the deformation promoting means is configured to deform in a bellows shape in the longitudinal direction of the vehicle body when the specified load is applied to the storage-container member substantially in the longitudinal direction of the vehicle body. Thereby, the impact load can be absorbed effectively. Accordingly, it can be properly restrained that the impact load is applied to the vehicle compartment. Further, the control of the specified load can be easily conducted by adjusting the number of bellows, the depth of bellows and the like. 
     Herein, the storage-container member stores various things in it, so its inside may become dirty easily. Accordingly, it may be preferable that the member be removed easily for its cleaning. Therefore, the storage-container member may be possibly configured to be merely inserted into the recess portion of the vehicle body from above, without using bolts or the like. In this case, however, there is a concern that the storage-container member would be removed out of the vehicle improperly when the impact load is applied to the vehicle body at the state of the trunk lid open. 
     According to another embodiment of the present invention, the storage-container member is inserted into a recess portion which is provided at the vehicle body from above, engagement portions which engage with each other are provided at the storage-container member and the vehicle body, and at the storage-container member is provided an engagement releasing means operative to release an engagement of the engagement portions with a manual operation. Thereby, since the engagement portions which engage with each other are provided at the storage-container member and the vehicle body, it can be properly prevented that the storage-container member is removed out of the vehicle when the impact load is applied to the vehicle body. Further, since the engagement releasing means operative to release the engagement of the engagement portions with the manual operation is provided at the storage-container member, the storage-container can be easily removed out of the vehicle body. 
     Other features, aspects, and advantages of the present invention will become apparent from the following description which refers to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Hereinafter, the baggage compartment structure of a vehicle according to preferred embodiments of the present invention will be described. 
     Embodiment 1 
     The baggage compartment structure according to the present embodiment is applied to a vehicle  1  shown in  FIGS. 1A ,  1 B. This vehicle  1  is an open-top type of vehicle in which a vehicle compartment  3  is provided at the central portion in the longitudinal direction of a vehicle body  2  and an upper portion above the vehicle compartment  3  can be opened. 
     A trunk room  6  is provided at the rear side of the vehicle body  2  of the vehicle  1 , specifically at a rear side of a portion between a rear end of the vehicle compartment  2  and a rear end of the vehicle body  2 . An opening  4  formed at an upper face of the trunk room  6  can be closed with a trunk lid  5 . 
     Further, the vehicle  1 , which is the open-top type of vehicle as described above, is equipped with roll bars  8 ,  8  which are respectively provided, behind right and left seats  7 ,  7 , on an upper face  2   a  of the vehicle body  2  between the vehicle compartment  3  and the trunk lid  5 . The roll bar  8  is to protect a passenger in case of the vehicle rolling over, which has a gate shape as shown in  FIG. 2  (a view, when viewed in a direction of an arrow A of  FIG. 1A ). 
     The trunk lid  5  is supported at the vehicle body  2  via a pair of binges  10 ,  10  which is provided at both ends of a front end portion of the lid  5  as shown in  FIGS. 1A and 1B . According to the present embodiment, the trunk lid  5  is configured to rotate around its front end by the hinges  10 ,  10  in such a manner that its back face in its open state faces substantially upward. 
     The hinge  10  comprises, as shown in  FIG. 4 , a support bracket  11  which is fixed to the vehicle body  2  and a swan-neck type of rotational arm  13  which is rotatably supported via a support axis  12  which is provided at an upper end portion of the support bracket  11 . The support axis  12  is positioned substantially at the same level as the upper face of the trunk lid  5 , so that the lid  5  can rotate in such a manner that the back face of the lid  5  faces substantially upward without interfering the vehicle-body upper face  2   a  behind the vehicle compartment  3  as shown by broken lines. 
     Further, a support mechanism  20  to support the trunk lid  5  in the open state ( FIGS. 3A ,  3 B) is provided in the present embodiment. 
     The support mechanism  20  comprises, as shown in  FIGS. 3A and 3B , a support portion  21  which is provided at the roll bar  8  so as to support the rear end portion of the trunk lid  5  and a lock mechanism  22  which locks the trunk lid  5  in its open state. 
     Herein, the support portion  21  is, as shown in  FIG. 2 , comprised of a difference-in-level portion  8   a  which is provided at the back face of an upper portion of an upper side portion  8   b  of the roll bar  8 , and a resilient member  222  to protect a deign face of the rear end portion of the trunk lid  5  is attached to the upper face of the difference-in-level  8   a.    
     Herein, as apparent from  FIG. 3B , the height of the support portion  21  is set such that an upper end α of the trunk lid  5  is higher than an upper end of a passenger Z with a specified size who is seated in a seat  7  (at a specified location) in the vehicle compartment  3 . 
     The lock mechanism  22  comprises, as shown in  FIGS. 1A ,  1 B,  3 A,  3 B, a roll-bar-side member  30  which is provided at the roll bar  8  and a lid-side member  40  which is provided at the rear portion of the trunk lid  5 . 
     The lid-side member  40  comprises, as shown in  FIGS. 5A and 5B , a support bracket  41  which is fixed to a lower face portion of the rear wall  5   a  of the trunk lid  5 , a bar member  42  which is rotatably supported at one end thereof so as to rotate around an axis  46  which is supported at the support bracket  41  so as to extend in the vehicle width direction, and an operational member  43  and an engagement member  44  which are supported so as to rotate around an axis  47  provided at the other end portion of the bar member  42 . The bar member  42  is configured to engage with a groove  45   a  of an engaging member  45  which is attached to the outer face of a trunk-room rear wall  2   c  of the vehicle body  2  when the lock mechanism  22  is not used. 
     Meanwhile, the roll-bar-side member  30  is, as shown in  FIG. 2 , attached in a recess portion  8   c  which is formed at the center of the upper portion of the upper side portion  8   b  of the roll bar  8 . The roll-bar-side member  30  comprises, as shown in  FIG. 6 , a base portion  30   a  and a pair of vertical wall portions  30   b,    30   b  which extend upward from right and left end portions of the base portion  30   a.  These portions  30   a,    30   b,    30   b  form a groove portion  30   c  which the bar member  42  of the lid-side member  40  can engage with. 
     As shown in  FIGS. 5A ,  5 B,  6 A,  6 B, engagement recess portions  30   d,    30   d  and engagement projection portions  44   a,    44   a,  which are configured to engage with each other, are provided at the front portion side of the inner face of the vertical wall portions  30   b,    30   b  of the roll-bar-side member  30  and the upper portion side (in the vertical direction in  FIGS. 5A ,  5 B) of the engagement member  44  of the lid-side member  40 . 
     As shown in  FIG. 7 , in a state in which the rear end portion of the trunk lid  5  in the open state is placed on the support portion  21  of the roll bar  8  via the resilient member  222 , the bar member  42  is rotated around the axis  46  by holding an operational portion  43   a  of the operational member  43 , so that the engagement between the recess portion  30   d  and the projection portion  44   a  is achieved as shown by broken lines. Then, the bar member  42  is further rotated around the axis  46  with the rotation of the operational member  43  and the engagement member  44  around this engagement portion, so that the engagement recess portion  30   d  of the engagement member  30  and the engagement projection portion  44   a  of the engagement member  44  are made in the engagement state shown by solid lines. In this engagement state, the locked state is maintained until the operation of the operational member  43  by the toggle mechanism. That is, even if the vehicle I travels with the trunk lid  5  open as shown in  FIGS. 3A ,  3 B, the trunk lid  5  can be properly prevented from fluttering due to the vehicle vibration or the like, and thereby any improper influence to the vehicle body can be prevented. 
     Thus, according to the present embodiment, even the large baggage, which may not be loaded with the trunk lid  5  in the closed state, can be loaded with the trunk lid  5  which is open by using the space above the opening  4  of the trunk room  6 . And, the vehicle  1  can travel in this state. Further, this advantage can be achieved without the large and complex structure and damaging the vehicle design. 
     Herein, since the rainwater comes into the trunk room  6  if the vehicle  1  travels with the trunk lid  5  open when it rains, it may be preferable that some proper measures to this be taken. 
     According to the present embodiment, as shown in  FIGS. 3A ,  3 B, the trunk room is comprised of a recess portion  2   b  which is formed by panels of the vehicle body  2  and a watertight storage-container member  50  (storage portion) which is made from resin, which is inserted into the recess portion  2   b  from above. 
     The storage-container member  50  comprises, as shown in  FIGS. 8 and 9 , a box portion  50   a  which is of a box shape and has an open upper face (forming the opening  4 ) and a flange portion  50   b  which is provided at an upper edge of the body portion  50   a.  The storage-container member  50  is supported at the vehicle body  2  with the flange portion  50   b  being placed on a flat-face portion  2   d  which is provided along the upper end portion of the recess portion  2   b  of the vehicle body. Accordingly, the storage-container member  50  can be removed of the recess portion  2   b  by being pulled up. 
     A seal member  51  is attached to the lower face of the flange portion  50   b  so as to prevent the rainwater or the like from coming into the recess portion  2   b  and some portion of the vehicle body  2  which is continuous to the recess portion  2   b.  Thus, according to the present embodiment, since the storage-container member  50  is provided, the inside of the recess portion  2   b  of the trunk room  6  or panels which form the vehicle body can be properly protected from the rainwater. 
     Further, at a bottom-face portion  50   c  of the storage-container member  50  are provided drains  50   d,    50   d  with caps, not illustrated. In a case in which the vehicle travels with the trunk lid  5  in the open state in the rain and the rainwater stays in the storage-container member  50 , the rainwater can be drained by removing the caps after taking out the storage-container member  50 . Also, when the storage-container member  50  becomes dirty, it can be easily cleaned with the water or the like after being removed from the vehicle body  2 . Further, the storage-container member  50  is so deep that its bottom is located close to the lower face portion of the vehicle body. Accordingly, even a tall baggage can be stored in it properly and stably. 
     Hereinafter, some examples of the baggage loading will be described. 
       FIG. 10  shows an example in which a tall baggage L 1  which is greater than the depth of the trunk room  6 . Thus, according to the baggage compartment structure of the present embodiment, even the tall baggage which is greater than the depth of the trunk room  6  can be properly loaded. 
     In this case, since the upper end a of the trunk lid  5  in the open state is positioned at the specified level which is higher than the upper end of the passenger Z with the specified size who is seated at the specified location in the vehicle compartment  3 , even if the baggage L 1  jumps out of the trunk room  6  when the vehicle has a rear collision, the trunk lid can protect the passenger of the vehicle from the baggage L 1  jumping out. 
       FIG. 11  is another example in which a baggage L 2 , such as a plant, having an upper portion with the longitudinal width which is greater than the opening  4  of the trunk room  6 . Thus, according to the baggage compartment structure of the present embodiment, even the baggage with the longitudinal width which is greater than the opening  4  can be properly loaded. 
     In the present embodiment, as shown in  FIGS. 3A and 3B , there are provided plural attachment portions  5   b  . . .  5   b  operative to attach an attachment, which will be described later, at the back face (an inner panel, for example) of the trunk lid  5 . Herein, by fixing this attachment to the attachment portions  5   b  . . .  5   b  when the trunk lid  5  is in the open state, the space above the trunk lid  5  and the opening  4  of the trunk room  6  can be used as the baggage-loading space. 
     For example,  FIG. 12  is another example in which a bicycle L 3  is loaded at the space above the trunk lid  5  and the opening  4  of the trunk room  6  by using support brackets  61 ,  62  as an attachment  60 . 
     The front support bracket  61  comprises a base portion  61   b  which has a pair of bolt holes  61   a,    61   a,  and a pair of standing portions  61   d,    61   d  which is provided so as to stand from the base portion  61   b  and has bolt holes  61   c,    61   c  at the upper end portion thereof, as shown in  FIG. 13A . 
     Meanwhile, the rear support bracket  62  comprises a base portion  62   b  which has a pair of bolt holes  62   a,    62   a,  and a pair of standing portions  62   d,    62   d  which is provided so as to stand from the base portion  62   b  and has bolt holes  62   c,    62   c  at the upper end portion thereof, as shown in  FIG. 13B . 
     Herein, the front support bracket  61  is fixed, as shown in  FIG. 14A , by applying bolts BB into nuts WN provided at the inner face of the attachment portion  5   b  at the back face of the trunk lid  5  through the bolt holes  61   a,    61   a  of the base portion  61   b  and bolt holes  5   h,    5   h  which are formed at the attachment portion  5   b  at the back face of the trunk lid  5 . Further, a bolt with an handle LB is inserted into front-wheel journal portions Fa (a groove portion and a hole portion) of a lower end portion of a front fork FF of a bicycle and the bolt holes  61   c  of the standing portion  61   d  of the front support bracket  61 . Then, by applying a pair of nuts with handles LN to the tips of the bolt LB, the front-wheel journal portions Fa are fixed to the front support bracket  61 . 
     Meanwhile, the rear support bracket  62  is fixed, as shown in  FIG. 14B , by applying bolts BB into nuts WN provided at the lower face of the flat-face portion  2   d  of the upper edge of the recess portion  2   b  of the vehicle body  2  through the bolt holes  62   a,    62   a  of the base portion  62   b  and bolt holes  50   h,    50   h  of the flange portion  50   b  of the storage-container member  50  and bolt holes  2   h,    2   h  formed at the flat-face portion  2   d.  Further, by placing the both ends of a rear-wheel axle bolt BR of the bicycle L 3  into the grooves  62   c  of the standing portions  62   d,    62   d  from above and by applying the nuts with handles LN to the both ends of the bolt BR, the rear side portion of the bicycle is fixed to the rear support bracket  62 . 
     Thus, by fixing the front portion and the rear portion of the bicycle L 3  to the trunk lid  5  and the vehicle body  2  via the attachments  61 ,  62 , the space above the trunk lid  5  and the opening  4  of the trunk room  6  can be used as the loading space of the bicycle L 3 . 
       FIG. 15  shows another example in which a surfboard L 4  is loaded in the space above the trunk lid  5  and the opening  4  of the trunk room  6 . 
     An attachment  70  for this is comprised of a pair of brackets  71 ,  71  and a pole member  72  as shown in  FIG. 16 . The support brackets  71 ,  71  comprise base portions  71   b,    71   b  which have a pair of bolt holes  71   a,    71   a  respectively and a pair of standing portions  71   d,    71   d  which is provided so as to stand from the base portions  71   b,    71   b  and has bolt holes  71   c,    71   c  at the upper end portions thereof respectively. 
     The pole member  72  is screwed to the upper ends of the support brackets  71 ,  71  with bolts  73 ,  73  through screw holes  71   c,    71   c.  That is, the pole member  72  can be disassembled. The base portions  71   b,    71   b  of the both support brackets  71 ,  71  are fixed to the attachment portions  5   b,    5   b  of the back face of the trunk lid  5  with screws like the support bracket  61 . 
     Then, as shown in  FIG. 15 , the lower portion of the surfboard L 4  is stored in the trunk room  6 , and its upper portion is fixed to the pole member  72  of the attachment  70  with a string or the like. Thus, the space above the trunk lid  5  and the opening  4  of the trunk room  6  is used as the loading space for the surfboard L 4 . 
     Herein, other long baggage than the surfboard L 4 , such as a wash-line pole, bow, plate, can be properly loaded by the attachment  70 . 
     Thus, according to the present embodiment, since the attachments  60 ,  70  are detachable to the trunk lid  5  or the vehicle body  2 , the space inside the trunk room  6  can be effectively used by removing the attachments  60 ,  70  when the trunk lid  5  is closed. Further, various kinds of attachment may be used, so various kinds of baggage can be loaded accordingly. 
     Since the attachments  60 ,  70  are fixedly or detachably provided at the specified position (attachment portion or the like) which enables the attachments  60 ,  70  to be located inside the trunk room  6  when the trunk lid  5  is closed, they are not viewed from the outside of the vehicle  1  when the trunk lid  5  is closed. Accordingly, the fine view of the vehicle  1  may not deteriorate. 
     Herein, if the baggage fixing means is relatively small, it may be provided at the specified position which enables it to be located inside the trunk room  6  so as to be integral with the back face of the trunk lid  5 , the storage-container member  50 , or the like. In this case, the operation of attaching or removing the attachment can be properly omitted. 
     While the attachment  60  for loading bicycle and the attachment  70  for loading surfboard or the like are described in the above-described embodiment, other various kinds of baggage may be loaded by applying attachments for other kids of baggage. Further, while the application to the open-top type of vehicle is described in the present embodiment, the present invention is applicable to another type, such as a sedan type, of vehicle. 
     Embodiment 2 
     A second embodiment of the present invention will be described referring to  FIGS. 17A ,  17 B- 21 . 
     A vehicle  101  of the second embodiment is configured such that a trunk lid  105  is opened to a substantially horizontal state as shown in  FIG. 18A ,  18 B. That is, as shown in  FIG. 19 , a hinge  110 , which is the swan-neck type like the first embodiment, is configured such that a support axis  112  is positioned at a higher level than the upper face of the trunk lid  105  and an upper face  102   a  of a vehicle body  102 , thereby enabling the trunk lid  105  to open substantially horizontally, without any interference with the upper face  102   a  of the vehicle body  102 , as shown by broken lines. 
     Returning to  FIGS. 17A ,  17 B, the longitudinal position of the hinge  110  and the longitudinal length of the trunk lid  105  are set so as not to interfere with roll bars  108  even if the trunk lid  105  opens substantially horizontally. Further, at the upper face  102   a  of the vehicle body  102  is formed a pair of notches  102   b  which extends in the vehicle longitudinal direction to avoid interference with a pair of rotational arms  113 . Further, as shown in  FIGS. 17A ,  17 B, a pair of support mechanisms  120  comprises a pair of support members  121  which is provided at the vehicle-body upper face behind the roll bars  108  and made of a resilient member, and a pair of lock mechanisms  122 . 
     The lock mechanism  122  has a similar structure to the first embodiment, but has a different disposition position. As shown in  FIGS. 17A ,  17 B,  20 A,  20 B, lid-side members  140  are provided at the rear face of a rear wall  105  of the lid  105 , and vehicle-body-side members  130  are attached to the vehicle-body upper face  120   a  beside the roll bars  108 . The basic structures of the members  130 ,  140  are substantially the same as those of the first embodiment, so their descriptions are omitted here. 
     As shown in  FIG. 21 , the rear portion of the trunk lid  105  is supported by the support member  121  in the sate in which the trunk lid  105  is open. Then, by making engagement between an engagement member  144  and the vehicle-body-side member  130  with operation of an operational member  143  of the lock mechanism  122 , the trunk lid  105  is locked in its open state. Other structures are similar to the first embodiment, and their descriptions are omitted here. 
     According to the above-described structure, as shown in  FIGS. 18A ,  18 B, any baggage L 5  which needs to be loaded substantially or any baggage which may not be stored inside the trunk room  106  can be properly loaded on the back face of the trunk lid  105 . In this case, the baggage L 5  may be fixed properly with a string whose hook is detachably provided at an attachment portion  105   b  at the back face of the lid  105 . Herein, the string engaging portion may be formed integrally with the back face of the trunk lid  105 . 
     Herein, in a case in which the attachment is used, the one having the suitable length to the present embodiment may be prepared properly. 
     In general, the traveling wind (air) tends to flow into the vehicle compartment in case of the open-top type of vehicle. Hereafter, other embodiments (third and fourth embodiments) equipped with measures for preventing the traveling wind from flowing in will be described. 
     Embodiment 3 
     At first, a third embodiment will be described referring to  FIG. 22 . A vehicle  201  according to the third embodiment is configured such that the vertical length of a rear wall  205   a  of the trunk lid  205  is longer than that of the second embodiment. This vertical length is set such that an upper end position γ (upper end in  FIG. 22 ) of a rear wall  205   a  of a trunk lid  205  in the open state is positioned at a specified level which is equivalent to or higher than the upper end position of the passenger, for example. 
     According to the present embodiment, the rear wall  205   a  of the trunk lid  205  can be made perform the aero-board function, merely by setting the vertical length of the rear wall  205   a  as described above. 
     Embodiment 4 
     A fourth embodiment will be described referring to  FIGS. 23A ,  23 B. A vehicle  301  of the fourth embodiment has an aero-board member  380  at a rear portion of the back face of a trunk lid  305 . 
     The aero-board member  380  is stored in a trunk room  306  so as to be located along the back face of an upper face portion  305   d  of the trunk lid  305  in the closed state of the trunk lid  305  as shown in  FIG. 24 . Its rear end portion (in  FIG. 24 ) is supported at a support axis  381  and a support bracket  382 , which are provided at the back face of the upper face portion  305   d  of the trunk lid  305 , so that the aero-board member  380  can rotate longitudinally. An engagement member  384  provided at its front end portion (in  FIG. 24 ) engages with an engagement member  383  provided at the back face of the upper face portion  305   d  of the trunk lid  305 . 
     Further, as shown in  FIG. 24 , an aero-board lock mechanism  390  which has a boar-side member  391  and a lid-side member  392  like the above-described lock mechanism is provided at the lower face of the aero-board member  380  and the lower face of a rear wall  305   a  of the trunk lid  305 . 
     Then, in the open state of the trunk lid  305  shown in  FIG. 25 , the aero-board member  380  is made stand up and herein the board-side member  391  and the lid-side member  392  of the aero-board lock mechanism  390  are made engage with each other. Thereby, the aero-board member  380  can be held in its standing state. The shape of the aero-board member  380  is preferably configured such that the level of its upper end γ′ is equivalent to or higher than the upper end portion of the passenger in the standing state. 
     According to the present embodiment, the function of the aero-board can be achieved by the aero-board member  380  provided at the trunk lid  305  even in a case in which the shape of the rear wall  305   a  of the trunk lid  305  may not be changed like the above-described third embodiment for the reason of design, for example. Further, since the aero-board member  380  can be properly located inside the vehicle body, the proper vehicle design can be maintained. 
     Herein, while the aero-board member  380  is supported at the back face of the trunk lid  305  so as to rotate according to the present embodiment, a bracket to fix the aero-board member to the attachment portion of the back face of the trunk lid may be provided at the aero-board member and the bracket may be fixed via bolts or the like. Thereby, the stricture may be simple without lock mechanism. 
     Embodiment 5 
     While the roll bar is provided near the seat in the vehicle compartment in the above-described first-fourth embodiments, there may be a case in which it is disposed rearward for the design reason or the like. In this case, however, there is a concern that the front end portion of the trunk lid interferes with the roll bar when the trunk lid opens so that the back face of the trunk lid faces substantially upward. Therefore, a fifth embodiment which solves this concern will be described. 
     That is, a vehicle  401  according to the fifth embodiment is configured, as shown in  FIGS. 26A ,  26 B, such that a roll bar  408  is disposed almost at the same longitudinal position as hinges  410  and a notch  405   e  is formed at the front end portion of the trunk lid  405 . 
     The width of the notch  405   e  is greater than that of the roll bar  408 , and its depth (longitudinal length) is set so that the move locus β of the front end of the notch  405   e  can extends passing over the upper end of the roll bar  408 . Accordingly, when the trunk lid  405  is opened to the state in which its back face faces substantially upward, it can be prevented that the trunk lid  405  interferes with the roll bar  408 . 
     Embodiment 6 
     A storage-container member  500  of the present embodiment comprises, as shown in  FIGS. 27 and 28 , a box portion  500   a  which is of a box shape and has an open upper face (forming the opening  4 ) and a flange portion  500   b  which is provided at an upper edge of the body portion  500   a.  The storage-container member  500  is supported at the vehicle body  2  with the flange portion  500   b  being placed on the flat-face portion  2   d  which is provided along the upper end portion of the recess portion  2   b  of the vehicle body. Accordingly, the storage-container member  500  can be removed of the recess portion  2   b  by being pulled up. 
     A seal member  510  is attached to the lower face of the flange portion  500   b  so as to prevent the rainwater or the like from coming into the recess portion  2   b  and some portion of the vehicle body  2  which is continuous to the recess portion  2   b.  Thus, according to the present embodiment, since the storage-container member  500  is provided, the inside of the recess portion  2   b  of the trunk room  6  or panels which form the vehicle body  2  can be properly protected from the rainwater. 
     Further, at a bottom-face portion  500   c  of the storage-container member  500  are provided drains  500   d,    500   d  with caps, not illustrated. In a case in which the vehicle travels with the trunk lid  5  in the open state in the rain and the rainwater stays in the storage-container member  500 , the rainwater can be drained by removing the caps after taking out the storage-container member  500 . Also, when the storage-container member  500  becomes dirty, it can be easily cleaned with the water or the like after being removed from the vehicle body  2 . Further, the storage-container member  500  is so deep that its bottom is located close to the lower face portion of the vehicle body. Accordingly, even the tall baggage can be stored in it properly and stably. 
     Herein, in the present embodiment, as shown in  FIGS. 27 and 28 , the storage-container member  500  has a plurality of folding portions  500   e  . . .  500   e  (deformation promoting means) which are properly collapsible in the longitudinal direction when the impact load is applied to the vehicle body  2  from the vehicle rear. 
     The folding portions  500   e  . . .  500   e  are comprised of plural grove portions  500   f  . . .  500   f  which are formed at both-side face portions and the bottom-face portion of the body portion  500   a,  and the flange portion  500   b.  The groove portions  500   e  . . .  500   e  are comprised of V-shaped grooves as shown in  FIG. 29 . When the impact load which is greater than a specified value is applied to the storage-container member  500  from the vehicle rear, the respective groove portions  500   f  . . .  500   f  bend, so that the storage-container member  500  is deformed so as to fold longitudinally in a bellows shape as shown in  FIG. 30 . 
     Accordingly, it can be properly restrained that the impact load is applied to the vehicle compartment  3  which is located in front of the trunk room  6  at the vehicle rear collision or the like. Thereby, the safety of the passenger in the vehicle compartment  3  can be improved. Further, since the storage-container member  500  is made of resin, the control of the above-described value of the impact load can be easily conducted by adjusting the thickness or the like of the resin member. 
     Further, since the folding portions  500   e  . . .  500   e  (deformation promoting means) are configured so as to fold in the longitudinal direction of the vehicle body in the bellows shape when the impact load which is greater than the specified value is applied to the storage-container member  500 , the impact load can be effectively absorbed. Accordingly, it can be properly prevented that the impact load is applied to the vehicle compartment  3 . Further, the control of the specified value of the impact load can be easily conducted by adjusting the number of bellows, the depth of bellows and the like. 
     Herein, the storage-container member  500  stores various things in it, so its inside may become dirty easily. Accordingly, it may be preferable that the member  500  be removed easily to be cleaned up. Therefore, the storage-container member  500  is configured to be merely inserted into the recess portion of the vehicle body from above, without using bolts or the like. In this case, however, there is a concern that the storage-container member  500  would be removed out of the vehicle improperly when the impact load is applied to the vehicle body  2  at the state of the trunk lid  5  open. 
     According to the present embodiment, as shown in  FIGS. 27 and 28 , at the front face portion and the rear face portion of the body portion  500   a  of the storage-container member  500  are respectively formed recess portions  500   g,    500   g  (engagement portions) which extend in the vehicle width direction and project toward the container inside. Further, at the front face portion and the rear face portion of the recess portion  2   b  of the vehicle body are respectively formed projection portions  2   e,    2   e  (engagement portions) which extend in the vehicle width direction and project toward the storage-container member  500 . The projection portions  2   e,    2   e  are formed at the position which corresponds to the recess portions  500   g,    500   g  of the storage-container member  500  stored in the recess portion  2   b,  so that the recess portions  500   g,    500   g  of the storage-container member  500  and the projection portions  2   e,    2   e  of the vehicle body  2  engage with each other in the application state. 
     Further, handling portions  500   i,    500   i  which project toward the inside of the member  500  at the front face portion and the rear face portion of the base portion  500   a  of the storage-container member  500  above the above-described recess portions  500   g,    500   g.  Further, the storage-container member  500  is configured as shown in  FIG. 31  such that the front face portion and the rear face portion of the base portion  500   a  deform toward the center of the member  500  as shown by the broken lines when the handling portions  500   i,    500   i  are pulled toward the center of the member  500  (for example, the thickness of these face portions are set to be deformable). Thereby, the engagement between the projection portion  2   e  of the vehicle body  2  and the recess portion  500   g  of the storage-container member  500  is releasable with a manual operation. 
     As described above, since the projection portions  2   e,    2   e  and the recess portions  500   g,    500   g  (engagement portions) which engage with each other are provided at the base portion  500   a  of the storage-container member  500  and the recess portion  2   b  of the vehicle body  2  according to the present embodiment, the storage-container member  500  can be prevented from being removed out of the vehicle improperly even when the impact load is applied to the vehicle body  2 . Also, since the handling portions  500   i,    500   i  (engagement releasing means) operative to release the above-described engagement with the manual operation are provided at the storage-container member  500 , the member  500  can be easily removed out of the vehicle body  2 , for example, when it is cleaned up. 
     Herein, in place of the folding portions  500   e  . . .  500   e,  another type of bellows-shape portion which does not contract perfectly at the initial stage but contracts further when receiving the impact load may be applied. Further, by weakening the strength of the side face portion, bottom face portion or flange portion of the body portion  500   a  compared with the strength of its front face portion and rear face portion, the deformation promoting means may be provided. 
     Embodiment 7
