Abstract

DC60 [Critical Issue] to obtain arm parts that confirmed that it could meet rigidity requirements and be easier to produce and achieve. Straddle vehicles that have this arm [IMPORTANT SOLUTION] The rear arm 60 consists of a pair of arms 61L, 61R supporting the respective axle end and cross section 70 by connecting the 61L arm, 61R, cross section 70, forming a shape by folding the thick flat part. single The rear end of the cross section 70 has a concave shape that goes towards the 62L, 62R pivot when looking at the rear arm 60 from the flange [selected image]. Figure 3 [Critical problem in fabrication] to obtain the arm part that is Insist that it meets the strength requirements and makes it easier to produce and achieve Straddle vehicles with this arm [Remedy for] The rear arm 60 consists of a pair of arms 61L, 61R supporting the respective axle end and cross section 70 by connecting the 61L arm, 61R, cross section 70 up shape by folding the thick flat part. single The rear end of the cross section 70 has a concave shape that goes towards the 62L, 62R pivot when looking at the rear arm 60 from the flange [selected image]. Figure 3.
