BODY FRAME FOR MOTORCYCLE

WIPO Patent Application WO/2006/109482

A1

A body frame (F) for a motorcycle, comprising a pipe-like main frame part (2) and a pivotally supporting frame part (3) extending downward from the rear end part of the main frame part (2). The left side half parts of the main frame part (2) and the pivotally supporting frame part (3) are formed of a semi-cylindrical left side frame half body (27L) formed of a series of plate members, and the right side half parts thereof are formed of a semi-cylindrical right side frame half body (27R) formed of a series of plate members. The opposed end parts of these left side frame half body (27L) and the right side frame half body (27R) are connected to each other to form a continuous hollow structure. In this case, each of the frame half bodies (27L, 27R) is formed by pressing a plate-like blank connected body. Thus, the number of components can be reduced, welding workability can be increased, and the yielding of materials can be increased.
