     DETAILED DESCRIPTION 
     Next, embodiments of the present invention will be described with reference to the drawings. In the following explanation, the left-right direction of the motorcycle (straddle vehicle)  1  is defined based on the view from a driver (rider) riding on the motorcycle  1 . Therefore, the front-rear direction coincides with a vehicle length direction and the left-right direction coincides with a vehicle width direction. The up-down direction (vertical direction) coincides with a height direction. 
     First, an outline of the motorcycle  1  of this embodiment will be described with reference to  FIG. 1 .  FIG. 1  is a side view of the motorcycle  1 . 
     As shown in  FIG. 1 , a motorcycle  1  is provided with a vehicle body  10 . The vehicle body  10  includes a plurality of body frames as a framework of the motorcycle  1 . The motorcycle  1  is provided with a head pipe  11  and a main frame  12  as the body frame. The configuration of the body frames is an example, and may be different. 
     The head pipe  11  has a shaft insertion hole for inserting a steering shaft (not shown). An upper bracket is located above the head pipe  11 . A lower bracket is located below the head pipe  11 . The upper bracket and the lower bracket have fork insertion holes for inserting the left and right front forks  15 , respectively. A front wheel  16  is rotatably attached to the lower part of the front fork  15 . A front tire  17  is attached on the front wheel  16 . 
     The main frame  12  is connected to the head pipe  11 . The main frame  12  is arranged to extend rearward from the head pipe  11 . An engine  21  is attached to the main frame  12  directly or via another member. A swing arm  22  is attached to the rear part of the main frame  12 . A rear wheel  25  is rotatably attached to the rear part of the swing arm  22 . A rear tire  26  is attached to the rear wheel  25 . 
     The engine  21  generates power, and the power is transmitted to the rear wheel  25  via the drive chain (not shown). This allows the motorcycle  1  to be driven. The engine  21  in this embodiment is a gasoline engine. In place of or in addition to the gasoline engine, another drive source, such as an electric motor for driving, may be provided. 
     A handlebar-type steering handle  28  is arranged near the upper end of the front fork  15 . By turning the steering handle  28  by the driver, the front forks  15  are turned so that the motorcycle  1  can be turned and the direction of travel can be changed. The motorcycle  1  is a lean type vehicle that is a vehicle in which the vehicle body  10  is inclined relative to a road surface toward a center of the turn when turning. 
     A fuel tank  29  is arranged behind the steering handle  28  and above the engine  21 , and the fuel tank  29  stores fuel for supplying the engine  21 . A seat  30  for the driver to be seated is arranged behind the fuel tank  29 . A step (not shown) is arranged on the left side and the right side of the vehicle body  10 , respectively. The driver straddles the seat  30  and places his feet on the left step and right step. Thus, since the driver is seated astride the seat  30 , the motorcycle  1  is a straddle vehicle. 
     A windscreen  31  is arranged in front of the steering handle  28 . The windscreen  31  is arranged to extend backwardly and upwardly from the lower end (base). With this configuration, the windscreen  31  guides the driving wind to make the driving wind less likely to hit the driver. The windscreen  31  is transparent or translucent, and the windscreen  31  can transmit visible light in order to ensure the driver&#39;s vision. 
     A headlight  32  is arranged in the front of the vehicle body  10  to irradiate the front of the vehicle. The light source of the headlight  32  is, for example, an incandescent bulb, a halogen bulb, a high-intensity-discharge (HID) lamp, or a light-emitting diode (LED). The headlight  32  of this embodiment is arranged so that the headlight  32  overlaps with the center of the vehicle width direction. The “overlap with the center of the vehicle width direction” means, for example, that the virtual line passing through the center of the motorcycle  1  in the vehicle width direction in plan view overlaps with the headlight  32 . The headlights  32  may be provided in pairs, for example, a pair of right and left headlights. 
     A cowl is arranged on the outer surface of the motorcycle  1 . The cowl is provided for the purpose of reducing the aerodynamic drag of the motorcycle  1 , protecting the various parts of the motorcycle  1 , and improving the appearance of the motorcycle. 
     In this specification, the cowl arranged primarily at the front part of the motorcycle  1  is referred to as the front cowl  33 . The front part of the motorcycle  1  is the part of the motorcycle  1  that is forward of the center in the vehicle length direction of the motorcycle  1 , for example, the part that is forward of the seat  30 . The front cowl  33  is shaped to protrude forward. Therefore, a recess is formed behind the front cowl  33  or in the front cowl  33 , and a space is formed by this recess in the front cowl  33 . The outline of the front cowl  33  includes portions that decrease in size in the vehicle width direction and in the height direction as they approach the front. As a result, the space in the front cowl  33  also includes portions that decrease in size in the vehicle width direction and height direction as they approach the front. In the front cowl  33 , a headlight  32  or the like is arranged. 
     Next, the camera  60  provided by the motorcycle  1  will be described. The camera  60  is located at the front part of the vehicle body  10 . Specifically, the camera  60  is located in front of the steering handle  28  and behind the windscreen  31 . The camera  60  is located so as to overlap with the center of the vehicle width direction. The camera  60  photographs an area in front of the motorcycle  1  through the windscreen  31 . In other words, the camera  60  detects visible light from the outside, which is transmitted through the windscreen  31 , and generates an image. The image generated by the camera  60  is output to the control unit (not shown). The control unit detects a foregoing vehicle, an oncoming vehicle, an obstacle, or a pedestrian, etc., based on the image, and performs control according to the detection result. For example, the control unit changes the irradiation direction or the irradiation position of the headlight  32  so as not to irradiate the light to the foregoing vehicle and the oncoming vehicle. Alternatively, the control unit operates the brakes to assist in preventing collisions with the obstacle or the pedestrian. 
     Next, a frame structure for supporting the camera  60  will be described with reference to  FIG. 2 . As shown in  FIG. 2 , the head pipe  11  has a cylindrical portion  11   a  in which a shaft insertion hole is formed, and an attachment base  11   b  extending forward from the cylindrical portion  11   a . The cylindrical portion  11   a  and the attachment base  11   b  are connected by welding, for example. 
     A support frame  40  is attached to the attachment base  11   b . The support frame  40  is connected to the head pipe  11  and is located forward of the head pipe  11 . The support frame  40  is a frame for supporting a plurality of electrical components including the camera  60 . The support frame  40  has a connection frame  41 , a branch frame  42 , a plate-shaped frame  43 , a hanging frame  44 , and a front frame  45 . 
     The connection frame  41  is a frame for connecting with the attachment base  11   b . The connection frame  41  is configured to allow insertion of the attachment base  11   b . The connection frame  41  and the attachment base  11   b  are connected by using, for example, a fixture such as a bolt and nut which are not shown in figures. The connection frame  41  and the attachment base  11   b  may be connected by welding. 
     The branch frame  42  includes a branch point. The branch frame  42  has a junction portion  42   a  at the rear side from the branch point and a branch portion  42   b  at the front side from the branch point. The junction portion  42   a  is connected to the connection frame  41 . The branch portion  42   b  branches from the branch point so as to spread to one side and the other side in the vehicle width direction. 
     The plate-shaped frame  43  is a plate-shaped member having an abbreviated L-shape. The plate-shaped frame  43  is connected to both the connection frame  41  and the branch portion  42   b . A plurality of stays for attaching electrical components and the like are connected to the front surface of the plate-shaped frame  43 . 
     The hanging frame  44  is an abbreviated U-shaped pipe-like member. One end of the hanging frame  44  is connected to the branch portion  42   b , and the other end of the hanging frame  44  is connected to the other side of the branch portion  42   b . As a result, the hanging frame  44  is supported in a hanging manner. A plurality of stays for attaching electrical components or the like are connected to the front side of the hanging frame  44 . 
     The front frame  45  extends in the vehicle width direction. In other words, the longitudinal direction of the front frame  45  coincides with the vehicle width direction. The front frame  45  connects the left and right branch portions  42   b . Specifically, the left end of the front frame  45  is connected to the left branch portion  42   b , and the right end of the front frame  45  is connected to the right branch portion  42   b.    
     The support frame  40  is provided with a meter stay  51 , a mirror stay  52 , and a camera stay  53 . The meter stay  51  is a member for attaching the meter device  34  and is connected near the branch point of the branch frame  42 . The meter device  34  is a display device that shows a vehicle speed and an engine speed, etc. The meter device  34  is attached by the meter stay  51  and other stays. The mirror stay  52  is a member for attaching the left and right side mirrors and is connected to both the branch portion  42   b  and the front frame  45 . The camera stay  53  is a member for attaching the camera  60  and is connected to the front frame  45 . A camera  60  is attached on the two camera stays  53 . The camera stays  53  are formed to project forward from the front frame  45 . This allows the camera  60  to be located forward. The forward position of the camera  60  makes it difficult to photograph the motorcycle  1  itself. 
     Next, the attachment structure for attaching the camera  60  to the camera stay  53  will be described with reference to  FIG. 3  to  FIG. 5 . After the vibration reduction cover  70  is attached to the camera  60  as shown in  FIG. 3 , the attachment cover  80  is further attached to the camera  60  as shown in  FIG. 4 . Thereafter, the attachment cover  80  is attached to the camera stay  53  as shown in  FIG. 5 . 
     The camera  60  is a rectangular shape (a rectangular parallelepiped shape, a cuboid shape) as shown in  FIG. 3 . In this specification, a rectangular shape includes a substantially rectangular shape. Thus, for example, even if at least one of the six surfaces includes a curved surface or a step, the camera  60  corresponds to a “rectangular shape”. Alternatively, the camera  60  corresponds to a “rectangular shape” even if at least one of the six surfaces is a shape other than a rectangle, or if a lens, a switch, or a connector, etc. is attached to at least one of the six surfaces. In other words, a rectangular shape is any shape in which three pairs of facing surfaces (e.g., top and bottom, left and right) are substantially recognizable. 
     The camera  60  is provided with a main body  61 , an intake lens (intake part)  62 , and a harness  63 . The main body  61  is a rectangular box-shaped member, in which an image sensor and the like are arranged inside. The intake lens  62  is a portion protruding in a certain direction from one surface of the main body  61 . The intake lens  62  includes a lens for taking in light from an outside. The harness  63  includes a power supply line to the main body  61  and a signal line for outputting image data obtained by the image sensor of the main body  61  to the control unit described above. The image data may be output wirelessly instead of wired. 
     The vibration reduction cover  70  is made of an elastic and flexible material (anti-vibration material) such as rubber. Accordingly, by deforming (enlarging) the vibration reduction cover  70 , the vibration reduction cover  70  can be attached to the camera  60 . As shown in  FIG. 3 , the outer shape of the vibration reduction cover  70  is a rectangular shape similar to the camera  60 . In the vibration reduction cover  70 , a space is formed in which the camera  60  can be arranged. The vibration reduction cover  70  has ribs  71 , a closure  72 , an opening portion  73 , and an insertion portion  74 . 
     The ribs  71  are formed on the inner surface of the vibration reduction cover  70 . The vibration reduction cover  70  has an open back for attaching the camera  60 . The ribs  71  are formed on all surfaces of the inner surface of the vibration reduction cover  70  except the surface on which the back of the camera  60  contacts. The closure  72  is formed on the back of the vibration reduction cover  70 . The closure  72  can change its position between an open state in which it is folded outwardly to increase the rear opening, and a closed state (as shown) in which it contacts the rear of the camera  60 . The closure  72  is configured to be easily deformable to facilitate attaching of the camera  60 . Specifically, the closure  72  has a crank-like bend and is also thinner than the other five surfaces. 
     The closure  72  also has function of reducing vibration of the camera  60  after the camera  60  is attached. All six surfaces of the vibration reduction cover  70  of this embodiment contacts the camera  60 . As long as the vibration reduction cover  70  contacts with at least two facing surfaces of the camera  60 , the number of contacting surfaces of the vibration reduction cover  70  may be five or fewer. Even in that case, it is possible to obtain stronger anti-vibration properties than in Japanese Patent No. 6178862. 
     The opening portion  73  is a through hole formed in the front surface of the vibration reduction cover  70 . The opening portion  73  is a portion for exposing the intake lens  62  of the camera  60  to the outside. The opening portion  73  allows the vibration reduction cover  70  to contact all six surfaces of the camera  60  without interfering with the photographing of the camera  60 . The opening portion  73  may have a different configuration as long as the intake lens  62  is capable of taking in light from the outside. For example, a transparent member (a member through which visible light is transmitted) may be provided by insert molding to block the opening portion  73 . 
     The insertion portion  74  is a portion for inserting the harness  63  of the camera  60 . The insertion portion  74  may be a through hole or a notch. The formation of the insertion portion  74  allows the vibration reduction cover  70  to contact all six surfaces of the camera  60  without interfering with the connection of the harness  63 . 
     The attachment cover  80  is made of metal or a hard resin. As shown in  FIG. 4 , the attachment cover  80  has a first cover  81  and a second cover  82 . The first cover  81  has a frame portion  81   a , a front hold portion  81   b , a lower attachment portion (first attachment portion)  81   c , and a joint portion  81   d . The second cover  82  has a rear hold portion  82   a , a lower hold portion  82   b , a lower attachment portion (first attachment portion)  82   c , a joint portion  82   d , and an upper attachment portion (second attachment portion)  82   e.    
     The frame portion  81   a  holds the upper, left, and right sides of the vibration reduction cover  70 . The front hold portion  81   b  holds the front surface of the vibration reduction cover  70 . The front hold portion  81   b  holds a position that avoids the intake lens  62  (i.e., the opening portion  73 ). If the intake lens  62  is surrounded by an inclined surface, the front hold portion  81   b  should hold a position that avoids the inclined surface. 
     The lower attachment portion  81   c  is a portion for attaching the first cover  81  to the camera stay  53 . The joint portion  81   d  is a portion for joining the first cover  81  and the second cover  82 . The lower attachment portion  81   c  and the joint portion  81   d  each have an insertion hole for inserting a bolt or other fixture. 
     The rear hold portion  82   a  holds the back of the vibration reduction cover  70  (e.g., the closure  72 ). The lower hold portion  82   b  holds the lower surface of the vibration reduction cover  70 . In addition, an insertion portion for inserting the harness  63  is formed in the lower hold portion  82   b . The insertion portion is a notch in this embodiment but may be a through hole. 
     The lower attachment portion  82   c  is a portion for attaching the second cover  82  to the camera stay  53 . The lower attachment portion  82   c  has a shape in which the lower hold portion  82   b  is extended horizontally. The joint portion  82   d  is a portion for joining the first cover  81  and the second cover  82 . The lower attachment portion  82   c  and the joint portion  82   d  each have an insertion hole for inserting a bolt or other fixture. As shown in  FIG. 5 , the lower attachment portion  81   c  and the lower attachment portion  82   c  are tighten together. Specifically, the lower attachment portion  81   c  and the lower attachment portion  82   c  are stacked and attached to the camera stay  53  by using a common fixture. This allows the first cover  81  and the second cover  82  to be joined while the attachment cover  80  is attached to the camera stay  53 . 
     Since the joint direction (axial direction of the fixture) of the joint portions  81   d ,  82   d  is in the front-rear direction, the joint enables the vibration reduction cover  70  to be firmly held so that the vibration reduction cover  70  is sandwiched between the front hold portion  81   b  and the rear hold portion  82   a . This reduces rattling in the front-rear direction and improves vibration reduction. Similarly, since the joint direction (axial direction of the fixture) of the lower attachment portions  81   c ,  82   c  is up-down direction, the joint enables the vibration reduction cover  70  to be firmly held so that the vibration reduction cover  70  are sandwiched between the frame portion  81   a  and the lower hold portion  82   b . This reduces rattling in the up-down direction and improves vibration reduction. In other words, in this embodiment, one surface of a pair of surfaces of the vibration reduction cover  70  facing each other in a first direction is held by the first cover  81  and the other surface of them is held by the second cover  82 . The first cover  81  and the second cover  82  are joined in the first direction. This reduces rattling in the first direction and improves vibration reduction. 
     The front hold portion  81   b  and the portion of the front surface of the vibration reduction cover  70  to be held are parallel planes. Therefore, since both of them are in contact with the surface, the force is applied evenly and stable holding can be achieved. Other five surfaces have the same configuration and the function as that of the surface described above. 
     The upper attachment portion  82   e  is a portion to which the connection member  90  described below is attached. The upper attachment portion  82   e  has a shape in which a portion of the rear hold portion  82   a  is extended upwardly (in detail, upwardly obliquely forward). 
     Next, with reference to  FIG. 6 , the connection member  90  will be described.  FIG. 6  shows a state in which the connection member  90  is further attached after the camera  60  is attached to the camera stay  53 . In  FIG. 6 , the front cowl  33  is appended with a chain line in order to show the positional relationship between the front cowl  33  and the connection member  90 . 
     The connection member  90  is a member for attaching the camera  60  more firmly and for preventing the camera  60  from being seen from the front. The connection member  90  is arranged so that at least a part of the connection member  90  overlaps the camera  60  in a front view. The connection member  90  has an upper attachment portion  91 , a cowl attachment portion  92 , an opening portion  93 , and a block portion  94 . 
     The upper attachment portion  91  is a portion for attaching with the upper attachment portion  82   e  of the second cover  82 . The upper attachment portions  82 ,  91  have an insertion hole for inserting bolt or other fixture. With this configuration, the attachment cover  80  and the connection member  90  are attached. 
     The upper attachment portion  82   e  is configured to extend upward from the rear hold portion  82   a , the upper attachment portion  82   e  is at a higher position than the camera  60 . Accordingly, the attachment cover  80  is attached to the connection member  90  at a higher position than the camera  60 . On the other hand, the lower attachment portion  82   c  is configured to extend horizontally from the lower hold portion  82   b . Accordingly, the contact point between the lower attachment portion  82   c  and the camera stay  53  is at a lower position than the camera  60 . In other words, the attachment cover  80  is attached to the camera stay  53  at a lower position than the camera  60 . Thus, in this embodiment, since the attachment cover  80  is attached to different members at both a position higher than the camera  60  and a position lower than the camera  60 , the posture of the camera  60  can be stabilized. 
     The attachment cover  80  is attached to the camera stay  53  forward of the center of the vehicle length direction of the camera  60 . On the other hand, the attachment cover  80  is attached to the connection member  90  behind the center of the camera  60  in the vehicle length direction. Accordingly, the posture of the camera  60  can be further stabilized. 
     The connection member  90  have the two cowl attachment portions  92 . Each of the cowl attachment portions  92  is forward of and lower than the camera  60 . Each of the cowl attachment portions  92  is arranged at left side and right side, respectively so that the left cowl attachment portion is located left side of the center of the vehicle width direction of the connection member  90  (or the camera  60 ) and the right cowl attachment portion is located right side of the center of the vehicle width direction of the connection member  90  (or the camera  60 ). The cowl attachment portion  92  is attached to the front cowl  33 . Specifically, attaching holes are formed in the cowl attachment portion  92  and the front cowl  33 . Bolts or other fixtures is used in a state where the cowl attachment portion  92  and the front cowl  33  is aligned. This allows the cowl attachment portion  92  to be attached to the front cowl  33 . 
     The opening portion  93  is a portion for exposing the intake lens  62  of the camera  60  to the outside. The opening portion  93  is formed so as to be located overlapping the intake lens  62  in the front view. In this embodiment, the shape of the opening portion  93  is polygonal. The shape of the opening portion  93  may be circular or any other shape. The intake lens  62  may project forward from the opening portion  93 , or the front end of the intake lens  62  and the front end of the opening portion  93  may be at substantially the same position in the vehicle length direction. 
     The block portion  94  is formed between the cowl attachment portions  92 . The block portion  94  is located in the center of the vehicle width direction of the connection member  90  (or the camera  60 ) and is formed to project forward. In this embodiment, a V-shaped opening is formed in the front cowl  33 , and the windscreen  31  is arranged in the opening portion. The inside of the front cowl  33  may be visible through the windscreen  31  from the base end of the V-shaped opening portion. Therefore, the block portion  94  is arranged to prevent the inside of the front cowl  33  from being seen. In this embodiment, the block portion  94  is rectangular in shape. The block portion  94  may be a V-shape (a shape in which the length in the vehicle width direction becomes shorter as it approaches the front) to match the V-shaped opening. 
     Next, with reference to  FIG. 6  and  FIG. 7 , an attachment structure of the windscreen  31  and a meter visor  35  will be briefly described.  FIG. 7  is a cross-sectional view of the camera  60  and the metering device  34  cut in a plane passing through the center of the vehicle width direction. 
     The windscreen  31  is attached by using the attachment holes  33   a  ( FIG. 6 ) formed in the front cowl  33 . The meter visor  35  is a cover that covers the front end and/or the top end of the meter device  34 , as shown in  FIG. 7 . The meter visor  35  is arranged behind the windscreen  31 . The meter visor  35  is attached to the front cowl  33  in the same manner as the windscreen  31 . The attachment hole  33   a  is different from the attachment hole for attaching the connection member  90 . 
     In other words, in this embodiment, the attachment structure for attaching the camera  60  (vibration reduction cover  70 , attachment cover  80 , connection member  90 , camera stay  53 , etc.) is independent of the attachment structure for attaching the windscreen  31  and the meter visor  35 . Therefore, the windscreen  31  and the meter visor  35  can be removed without removing the camera  60 . Accordingly, it is not necessary to remove the camera  60  when the windscreen  31  is removed in order to prevent chemicals from adhering to the windscreen  31  during car washing. Conversely, the camera  60  can be removed without removing the windscreen  31  and the meter visor  35 . Accordingly, it is not necessary to remove the windscreen  31  and the meter visor  35  when maintaining the camera  60 . 
     As described above, the motorcycle  1  of this embodiment includes the camera stay  53 , the camera  60 , the vibration reduction cover  70 , and the attachment cover  80 . The camera  60  photographs the front area of the motorcycle  1 . The vibration reduction cover  70  is made of the elastic material and covers at least two surfaces of the camera  60  facing each other. The attachment cover  80  holds the camera  60  via the vibration reduction cover  70  and is attached to the camera stay  53 . 
     This allows the camera  60  to be attached to the vehicle body  10  while reducing the vibration of the camera  60  with a simple structure. In addition, by covering the two facing surfaces of the camera  60  with the vibration reduction cover  70  and holding it with the attachment cover  80 , the camera  60  can be firmly attached to the camera stay  53  while reducing the vibration. 
     The motorcycle  1  of this embodiment includes the front cowl  33  and the connection member  90 . The front cowl  33  is arranged at the front part of the vehicle (motorcycle). The connection member  90  connects the attachment cover  80  to the front cowl  33 . 
     The attachment cover is attached to not only the camera stay  53  but also the front cowl  33  via the connection member  90 . Therefore, the posture of the camera  60  can be stabilized. 
     In the motorcycle  1  of this embodiment, the attachment cover  80  includes lower attachment portions  81   c ,  82   c  and upper attachment portion  82   e . The lower attachment portions  81   c ,  82   c  are attached to the camera stay  53  so that the attachment position is below the camera  60 . The upper attachment portion  82   e  is attached to the connection member  90  so that the attachment position is above the camera  60 . 
     Accordingly, since the camera  60  is attached to the attachment cover  80  at below and above the camera  60 , the posture of the camera  60  is more stabilized. 
     In the motorcycle  1  of this embodiment, the camera  60  includes the main body  61  and the intake lens  62  that takes in light from the outside into the main body  61 . The connection member  90  has the opening  93  so that the opening portion  93  and the intake lens  62  overlaps in a front view. 
     Since the connection member  90  is attached to the attachment cover  80  above the camera  60 , the layout is likely to be such that the connection member  90  overlaps the intake lens  62  of the camera  60 . In this regard, the opening portion  93  formed in the connection member  90  prevents the connection member  90  from interfering with the photographing of the camera  60 . 
     The motorcycle  1  of this embodiment includes the windscreen  31  for protecting the driver from the driving wind. The camera  60  is arranged at the rear of the windscreen  31  and photographs through the windscreen  31 . 
     This allows the camera  60  to be protected from flying objects or the like. 
     In the motorcycle  1  of this embodiment, the windscreen  31  is attached to the front cowl  33 . The attachment structure for attaching the connection member  90  to the front cowl  33  is independent of the attaching structure for attaching the windscreen  31  to the front cowl  33 . 
     This allows only one of either the camera  60  or the windscreen  31  to be removed. Therefore, only the camera  60  can be removed for maintenance or only the windscreen  31  can be removed for car washing. 
     The motorcycle  1  of this embodiment includes the support frame  40  which is located in front of the head pipe  11 , and supported by the head pipe  11 . The support frame  40  supports at least one electrical component other than the camera  60 . The support frame  40  includes a plurality of stays, and one of the stays is the camera stay  53 . 
     This allows the camera  60  and other electrical components to be supported together. 
     In the motorcycle  1  of this embodiment, the attachment cover  80  has the first cover  81  and the second cover  82 . By joining the first cover  81  and the second cover  82 , the vibration reduction cover  70  is sandwiched between the first cover  81  and the second cover  82 . Both of the first cover  81  and the second cover  82  are attached together on the camera stay  53 . 
     Accordingly, since not only joining the first cover  81  and the second cover  82  but also attaching the first cover  81  and the second cover  82  to the camera stay  53  together, the camera  60  can be held firmly. 
     In the motorcycle  1  of this embodiment, the camera  60  is a rectangular shape. The vibration reduction cover  70  covers each of the six surfaces of the camera  60 . The attachment cover  80  contacts each of the six surfaces of the vibration reduction cover  70 . 
     This can make it difficult for vibrations in various directions to be transmitted to the camera  60 . 
     While a preferred embodiment and variations of the present invention have been described above, the configurations described above may be modified, for example, as follows. 
     The camera  60  of the above embodiment has a shape in which the intake lens  62  protrudes from the main body  61 . The intake lens  62  of the camera  60  need not protrude from the main body  61 . The camera  60  is not limited to a rectangular shape and may have different shapes. 
     The vibration reduction cover  70  of the above embodiment is an integrally configured member. The vibration reduction cover  70  may be composed of a plurality of components. 
     The attachment cover  80  of the above embodiment consists of two separable parts. The attachment cover  80  may consists of one part or three or more parts. The plurality of parts consisting of the attachment cover  80  may be configured to be welded or press-fitted together instead of using fixtures such as bolts. 
     In the above embodiment, an example of applying the present invention to a motorcycle  1  is described, but the present invention can also be applied to other straddle vehicles. Other straddle vehicles are, for example, vehicles with two front wheels and one rear wheel, vehicles with one front wheel and two rear wheels, vehicles with two front wheels and two rear wheels, or the like. Other example of a four-wheeled vehicles are all terrain vehicle (ATV), which is primarily used for driving on unpaved terrain.
