Abstract: The main step structure for the saddle riding vehicle includes a fixing member, a step pin, a main step, and a biasing member that biases the main step in a developing direction. The main step structure includes an operating member supported to be rotatable relative to the main step. The operating member is provided with a contact section that makes contact with the fixing member. An engaging mechanism that can switch between an engaged state and a disengaged state of the main step and the operating member is provided. In the case where the main step is moved to an accommodated position and the operating member is made to make contact with the fixing member, the engaging mechanism puts the main step and the operating member into an engaged state.

Abstract: Lateral sides of an engine and a fuel tank are covered with a tank cowling formed by connecting a front cowling and a rear cowling. The front cowling is provided with a flange in which a through hole is formed. The long sides of the through hole are formed in parallel with a cylinder axis of a cylinder section. A gate provided on a lower connecting edge portion of the rear cowling with which the flange overlaps is inserted into the through hole and connected by the clip. The front cowling and the rear cowling are fastened through a bolt on a vehicle body side above and below the connecting section by the clip. With this structure, the force applied to the connecting section is reduced and the connecting section is decreased in size.
