Problems solved by technology

A second crossbar as a reinforcement member becomes necessary, resulting in an increase in the weight of the frame
[0006] In addition, if the bracket is simply made thinner, the strength of the bracket will be lowered. Therefore, it is necessary to improve the rigidity of the bracket by making the bracket thicker.
[0007] When the bracket is made thicker, the weight of the frame is further increased

Abstract

Disclosed is a vehicle frame structure that includes a left-right pair of rear frames (20L, 20R) a cushion (35L, 35R) being attached to each of the frames. The frame structure further includes brackets (80L, 80R) provided to each of the rear frames; each of the rear frames has a frame-penetrating hole (83, 85) that penetrates in the widthwise direction of the vehicle, the brackets each have a bracket-penetrating hole (93, 96) that penetrates in the widthwise direction of the vehicle; in a manner so that the axes (127, 128) of the bracket-penetrating holes are caused to respectively match the axes (129, 131) of the frame-penetrating holes, cushion bolts (120L, 120R) for fastening the upper ends (134L, 134R) of the cushions to the rear frames are threaded through the frame-penetrating holes and the bracket-penetrating holes and welded to the rear frame; and the cushion bolts are welded to the bracket.

Description

technical field [0001] This invention relates to the improvement of the frame structure of a vehicle. Background technique [0002] Generally, a shock absorber for absorbing a load acting on the rear wheels is provided at the rear of the motorcycle. Various frame structures for supporting the shock absorber have been proposed (for example, Patent Document 1). [0003] The motorcycle disclosed in Patent Document 1 is equipped with a shock absorber on the rear frame and the rear end of the rear fork. [0004] In the aforementioned two-wheeled motor vehicle, a bracket is further provided at an intermediate portion of the rear frame, and shock absorber bolts for supporting the rear shock absorber are provided on the bracket. In the above-mentioned two-wheeled motor vehicle, the second cross bar extends between the left and right brackets, and the shock absorber bolts extend outward from the brackets in the vehicle width direction. [0005] That is, the rigidity of the bracket...
