Abstract

The body structure for saddled vehicles comprises a first frame (21), a second frame (23), and a patch (30) joined to the first frame (21) and the second frame (23). The patch (30) is joined to the bent portion (21 c) of the first frame (21). A weld (23w) of the second frame (23), where the patch (30) and the second frame (23) are joined, is provided on the patch (30). A joining portion (31h) where the patch (30) and the first frame (21) are joined is provided at a different portion of the patch (30) to where the weld (23w) of the second frame (23) is located.

Description

technical field [0001] The present invention relates to a body structure of a straddle type vehicle. [0002] This application claims priority based on Japanese Patent Application No. 2017-060983 for which it applied on March 27, 2017, and uses the content here. Background technique [0003] Conventionally, in the body structure of a straddle-type vehicle, a structure in which a seat frame is directly welded to a main frame to which a plurality of members are welded is known. For example, Patent Document 1 discloses a technique of laser welding a front frame and a rear frame after joining the head pipe and the like to the front frame by welding. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2015-189426 [0007] Summary of the invention [0008] The problem to be solved by the invention [0009] However, since the residual stress due to the welding condition of each member joined to the main frame diffe...
