By using the spacer collars 48 and 50, the fastening force of the bolts 47 and 49 does not directly reach the resin fastening seats 38 and 40.

  In the saddle-ride type vehicle 1 configured as described above, the rider's feet put on the footboard 15 with the boots on the foot board 15 are only the footrest protrusions as shown in FIG. It rests on the upper surface of 21 and the toes and heels are in a floating state. Further, at the time of sudden acceleration, sudden braking, jumping, turning, etc., as shown in FIG. 10, the bottom surface of the toe can be brought into close contact with the front surface area 22 of the footboard formed in the shape of a front-lowering slope. This makes it easier for the rider to step on and improves steering stability. In this case, since the contact area between the bottom surface of the toe and the front area area 22 of the footboard is large, the contact with the shoe sole is locally strengthened and the rider does not feel uncomfortable.

  In addition, since the height of the footboard rear area surface 23 is lower than the height of the rearmost part of the footboard front area surface 22 and the footboard rear area surface 23 is formed substantially horizontally, The bottom surface of the footboard is less likely to reach the footboard rear area surface 23, and the footrest convex portion 21 and the footboard front area surface 22 are more likely to be put on the weight, so that the handling stability can be improved in this respect as well.

  Since a shock absorbing member 36 is interposed between the footrest convex portion 21 and the main bracket portion 31 (bracket arm 33), the shock absorbing member 36 absorbs engine vibration and vehicle body vibration to the rider's foot. It provides anti-vibration action, which improves ride comfort. Since the buffer member 36 is fitted in a concave lateral groove 37 provided on the lower surface of the footrest convex portion 21, the buffer member 36 is not crushed in the vehicle front-rear direction and spreads thinly even when the rider's weight is applied. For this reason, the capacity | capacitance (height) of the buffer member 36 can be enlarged and sufficient anti-vibration performance can be obtained. In addition, since the buffer member 36 is not easily crushed, the support rigidity (or rigidity) of the footboard 15 can be increased.

  In addition, the outer edge portions 25 and 26, which are one step higher, are provided at the outer end portions in the vehicle width direction of the footboard front area surface 22 and the footboard rear area surface 23, so that the footboard front area surface 22 and the footboard rear side The area surface 23 is formed in a concave shape to improve the rider's foot retention, which can effectively prevent slipping or stepping of the foot even if slippery mud etc. accumulates on the footboard 15 . Moreover, since the non-slip uneven pattern 27 is also provided on the upper surfaces of the outer edge portions 25 and 26, it is possible to place a foot on this and improve the freedom of the riding position.

  Furthermore, a footrest bracket 30 that supports the footboard 15 from below is provided with a main bracket portion 31 that extends from the inside to the outside in the vehicle width direction, and a sub bracket portion that is fixed to the tip of the main bracket portion 31 and extends in the vehicle front-rear direction. Therefore, for example, the structure can be greatly simplified and the weight can be greatly reduced as compared with the case where the footrest bracket 30 is formed in a loop shape. Further, the rigidity in the vicinity of the tip of the sub bracket portion 32 can be deliberately reduced, and the vibration applied to the foot board 15 can be absorbed to improve the vibration isolation.

  Since the sub bracket portion 32 is fitted into a concave vertical groove 39 formed under the outer edge portions 25 and 26 of the foot board 15, the sub bracket portion 32 is not exposed to the appearance in a side view. The appearance around the board 15 can be greatly improved.

  The peripheral structure of the footboard according to the present invention can be widely applied not only to a four-wheel straddle-type vehicle but also to a three-wheel or two-wheel straddle-type vehicle (motorcycle, scooter type vehicle, etc.). it can.
