Problems solved by technology

[0006] However, in the conventional straddle-type vehicle described above, the pair of engine mounting bosses and the pair of rear bumper link bosses are arranged offset from each other in the vehicle width direction. The loads transmitted by the engine act to bend the beam, possibly exerting loads on the beam that deform it
Therefore, it is necessary to use a large beam with high strength, which makes it difficult to achieve weight reduction

Abstract

A saddled vehicle having a cross-member which is reduced in weight by preventing a non-uniform load from acting on the cross-member. A saddled vehicle provided with: a vehicle body frame (11) for suspending an engine (12); a swing arm (14) for pivotably suspending a rear wheel (WR); a pair of left and right pivot sections (29) for forming a part of the vehicle body frame (11) and pivotably supporting the swing arm (14); a lower cross-member (28) for connecting the pivot sections (29); a rear cushion (32) for applying an elastic force to the swing arm (14); a link mechanism (31) to which the lower end (32A) of the rear cushion (32), the swing arm (14), and the pivot sections (29) are connected; link connection stays (70) which are formed behind the lower cross-member (28) and to which the link mechanism (31) is connected; and lower hangers (48) which are formed in front of the lower cross-member (28) and to which the engine (12) is affixed. The link connection stays (70) are formed at the same position in the widthwise direction of the vehicle, and so are the lower hangers (48).

Description

technical field [0001] The present invention relates to a straddle type vehicle provided with a link mechanism on a rear shock absorber. Background technique [0002] Conventionally, a straddle-type vehicle is known in which a vehicle frame includes a pair of left and right pivot plates, a cross member connecting the lower ends of the left and right pivot plates, and a cross member provided at the front of the cross member. There are a pair of bosses for mounting the engine, and a pair of bosses for a rear bumper link connecting the rear bumper are formed at the rear of the beam (for example, refer to Patent Document 1). [0003] 【Prior technical literature】 [0004] 【Patent Literature】 [0005] [Patent Document 1] Japanese Patent Laid-Open No. 2007-62618 [0006] However, in the above-mentioned conventional straddle-type vehicle, the pair of engine mounting bosses and the pair of rear bumper link bosses are arranged offset from each other in the vehicle width direction. ...
