Description of the Invention: [Technical Field of the Invention] The present invention relates to a locomotive having a footrest on which a rider's foot can be placed. [Prior Art] It is known that the footrest of the locomotive is configured to extend from the side stand bracket fixed to the side of the vehicle body to the side of the vehicle to place the rider's foot, and the base end portion is rotatably supported by the brake pedal or Foot pedals such as a shift pedal. The base end of the foot support shaft supports the base portion to rotate from #, so that the foot portion rotates upward when the vehicle falls down, and maintains the rotation axis of the foot portion in the correct direction, in the pedal The baffle structure is used for the installation of the board and the footrest bracket. The attachment structure of the footrest disclosed in the following Patent Document 1 is a bearing ' provided at the base end portion of the footrest, and a convex portion is formed at the base end surface thereof, and the convex portion extends toward the vehicle inner side, and its profile The shape is non-circular and has a threaded hole at the center; on the other hand, a recess is formed on the side of the stand support, the recess has a cross-sectional shape corresponding to the convex portion and has a bolt insertion hole at the center . Further, the pedal portion and the footrest bracket are locked by the mounting bolt inserted from the inside of the vehicle when the projection on the side of the footrest is inserted into the side of the footrest bracket. At this time, according to the structure disclosed in the patent document described later, the periphery of the convex portion of the footrest and the periphery of the concave portion of the footrest bracket are used as the text pressing surface to resist the fastening force generated by the mounting bolt. [Patent Document 1] 曰本特开〇〇2〇〇1 _1丨4] No. 67 [Invention] [Problems to be Solved by the Invention] 134293.doc 1361772 40 rotatively supports a brake pedal 8〇. The footrest 4G on the left side of the handle and the footrest 40 on the right side of the handle are attached to the vehicle body in the same mounting structure. Therefore, in the following description, the mounting structure of the footrest 4〇 on the left side of the vehicle will be mainly described, and the detailed description of the mounting structure of the footrest 40 on the right side of the vehicle body will be omitted. As shown in Fig. 3 and Fig. 5, the diascript stand support 2 is formed in a side view in which a front end portion of the V-shaped portion which is open to the front of the vehicle body is a mounting portion 22 having a bolt hole. The mounting portions 22 are locked to the bracket 12 extending rearward from the main frame 2b by bolts. Further, at the upper end portion of the footrest bracket 20, two attachment portions 24' extending upward are formed. These attachment portions 24 are locked to the heel guard plate a by screwing. Further, a mounting portion 26 for mounting the footrest is provided at a rear portion of the footrest bracket 20. The mounting portion 26 has a circular mounting surface 26P that faces outward, and a bolt insertion hole _ 26a that penetrates in the vehicle width direction is formed at a central portion thereof, and is obliquely separated from the screw insertion hole 26a in the mounting surface 26p. In the upper position, the pin hole is inserted from the surface toward the inner side in the vehicle width direction. Further, the direction in which the pin hole 26b is located with respect to the center of the bolt insertion hole 26a is the foot portion 48 of the footrest 40 to be described later. The direction of rotation is the same. In the mounting portion 26, as shown in Fig. 4, the bolt 50 is inserted into the bolt insertion hole 26a from the inside in the vehicle width direction, and then the footrest 4 is locked to the outside (where the bolt is inserted in the mounting surface 26p) The periphery of the hole 26a is a pressure receiving surface for locking the footrest 4's. Further, the pin hole 26b is inserted as a footrest ^ 134293.doc 1361772, and is supported by the holder portion 46. The rotation direction of the leg portion 48 of the shaft support is the same. On the other hand, the pin hole 26b' formed on the mounting surface 26p of the footrest bracket 20 is located at a position obliquely rearward and upward with respect to the bolt insertion hole 26a. The footrest 40 and the footrest bracket 20 are locked in a state in which the pins 60 as the rotation stoppers are commonly inserted into the pin holes 42b and 26b. Therefore, the foot φ table 40 is positioned at In the circumferential direction, the leg portion 48 is locked to be tilted rearward and upward (see FIG. 3). Further, the washer 7 between the footrest 40 and the footrest bracket 20 also has the insertion pin 60. The pin hole 72 is not limited to the circular shape of the embodiment, and may be a rectangular shape or the like, and is not particularly limited. According to the present embodiment described above, since the base end surface 42p of the support shaft portion 42 of the footrest 40 is formed flat (that is, because it is formed to have the same size as the J-face of the support shaft portion 42), The entire base end surface 42p is a pressure receiving surface, and a sufficient tightening force can be applied by the bolts 5'. As a result, the support shaft portion 42 can be reduced in diameter, and the footrest 4 can be miniaturized. Further, in the present embodiment, the pin hole 42b formed in the base end surface 42p of the footrest 4〇 and the pin hole 26b_ formed in the mounting surface 26p of the footrest bracket 2〇 are inserted with the common pin 6〇. By this, since the pin holes 42b and 26b are respectively penetrated, the rotation stop structure of the footrest 40 can be easily formed as compared with the case where the pin is formed in either of them. Further, in the present embodiment, it is formed in the present embodiment. The bolt insertion hole 26a and the pin hole 26b of the footrest bracket 2 are formed in parallel with the screw hole 42a and the pin 134293.doc!2 1361772 hole 42b formed in the footrest 4, thereby being easy to be formed. The bolts 5〇 and the pins 60 are inserted in the ground to facilitate the mounting of the footrests 40. In the present embodiment, the pin hole 42b formed in the base end surface 42p of the footrest 40 is provided between the screw hole 42a formed in the base end surface 42p and the outer peripheral surface 42c of the support shaft portion 42. Since the pin 60 of the insertion pin hole 42b can be disposed further inside than the outer circumferential surface 42c of the support shaft portion 42, the pin 60 can be protected. φ In addition, in the present embodiment, the base end surface 42p of the footrest 40 is disposed. The pin hole 42b is formed at a position spaced apart from the screw hole 42a in the rotational direction spaced apart from the leg portion 48. Thereby, the same type can be applied to either the left side of the vehicle or the right side of the vehicle. The footrest is 4 〇. Further, the present invention is not limited to the embodiments described. For example, a pin protruding from the base end surface of the footrest may be provided, and the pin may be inserted into a pin hole formed in the mounting surface of the footrest bracket. Further, a slit may be provided in the outer periphery of the support shaft portion of the footrest, and a pin may be embedded in the slit.
