The auxiliary rib pair 105 includes the two auxiliary ribs 102A in such a manner that the two auxiliary ribs 102A expand and move away from each other as they approach the electrical component.

  When a load is applied to the lid portion 57, the auxiliary rib pair 105 deforms and bends in mutually different directions (a direction approaching each other, a direction moving away from each other, a direction narrowing each other, or a direction moving away from each other). The bending of the auxiliary rib pair 105 counteracts the reaction force in the width direction of the motorcycle 1 due to the deformation of the auxiliary rib 102A, and reduces the load in the width direction of the motorcycle 1 on the electrical component.

  The rigidity of the auxiliary rib 102 </ b> A is adjusted depending on the direction in which the auxiliary rib 102 </ b> A hangs down (the angle formed on the back surface of the lid 57), the curvature (curvature radius) of the hanging shape, the thickness, and the material of the lid 57.

  The lid 57 including the reinforcing rib 101 and the auxiliary rib 102A is loaded from the top surface side by being stepped on by the passenger. Therefore, the electrical component storage structure 71A of the motorcycle 1 according to the present embodiment transmits and supports the load to the bottom of the electrical component mounting box 56 and the electrical component by the reinforcing rib 101 and the auxiliary rib 102A to deform the lid portion 57. While restraining, the cover 57 is firmly supported by deforming the auxiliary rib 102A to reduce the load on the electrical component and transmitting the load from the reinforcing rib 101 to the electrical component mounting box 56.

  The electrical component storage structures 71, 71 </ b> A of the motorcycle 1 according to the present embodiment include the reinforcing rib 101 provided on the back surface of the lid portion 57 and the auxiliary rib 102 having a rigidity lower than that of the reinforcing rib 101. While reducing the burden of the load on the product, it is possible to enhance the attractiveness of the vehicle by increasing the sense of rigidity when the occupant places his / her legs on the lid portion 57.

  In addition, the electrical component storage structures 71 and 71A of the motorcycle 1 according to the present embodiment mainly share the load while avoiding the burden of the load on the electrical component by extending the reinforcing rib 101 to the side of the electrical component. The cross-sectional secondary moment of the reinforcing rib 101 can be sufficiently secured as compared with the auxiliary rib 102, and the rigidity of the lid portion 57 can be easily increased.

  Furthermore, the electrical component storage structure 71A of the motorcycle 1 according to the present embodiment includes the auxiliary rib 102A extending in an arc shape or inclined toward the electrical component, thereby reliably avoiding a load on the electrical component. can do.

  Therefore, according to the electrical component storage structures 71 and 71A of the motorcycle 1 according to the present embodiment, the burden on the electrical components in the electrical component mounting box can be reduced.
