| 摘要 |
A motorcycle seat frame, wherein a bottom surface part extending in a vehicle longitudinal direction and side surface parts standing upward at least at positions on both sides in a vehicle width direction of the bottom surface part are made of a fiber reinforced resin, thereby making an efficient improvement in the bending stiffness in a vehicle vertical direction possible using the anisotropy of the fiber reinforced resin, and also making marked weight reduction as a whole possible. Provided is a motorcycle seat frame which achieves an efficient increase in bending stiffness in a desired direction in terms of material without improvement in mechanical structure, and enables marked weight reduction while required bending stiffness is ensured. |
