The shaft support portion 43 is accommodated in a space 28s defined by the side wall portion 28a and the upper wall portion 28b of the bracket 28 in a use state. The upper wall portion 28b of the bracket 28 is formed to avoid the turning locus of the shaft support portion 43 from the storage state to the use state.

The shaft support portion 43 has a side surface 43a that abuts against the side wall portion 28a of the bracket 28 in the use state. In the use state, the side surface 43a of the shaft support portion 43 abuts against the side wall portion 28a of the bracket 28 from the outside in the vehicle width direction. The side wall portion 28a of the bracket 28 functions as a holding portion for holding the step plate 40 in a state of extending in the vehicle width direction in a use state.

As described above, in the step structure 39 of the motorcycle 1 of the above embodiment, in the step structure 39 of the motorcycle 1 including the step 40 which is swingably moved up and down between the use state in which it is raised in the vehicle width direction and the storage state in which it is tilted along the vehicle side surface, the step 40 is rotatable about a shaft 27 provided on the vehicle body frame 20, the step 40 includes a first projecting portion 41 extending in a first direction V1 along a direction intersecting the shaft 27 and a second projecting portion 42 extending in a second direction V2 opposite to the first direction V1, in the stored state, the first projecting portion 41 and the second projecting portion 42 are tilted along the side of the vehicle, in the use state, the first projecting portion 41 is raised outward in the vehicle width direction, and the second projecting portion 42 is housed in the recessed portion 34b provided in the vehicle body cover 30 so as to be directed inward in the vehicle width direction.

According to this configuration, in the use state, the first projecting portion 41 of the step plate 40 can function as a foot rest portion for the passenger, and the second projecting portion 42 can be housed in the recessed portion 34b of the vehicle body cover 30. Therefore, the step plate 40 can be prevented from protruding excessively outward in the vehicle width direction in the use state.
