摘要： PROBLEM TO BE SOLVED: To prevent the deformation of a head member caused by the fixing of a valve guard to a head member, and to reduce the thickness of the head member without complicating a shape of the head member or the like.
SOLUTION: The valve guard 63b is disposed to a front muffler 63. That is, the valve guard is not directly fixed to a front head 61 with a fastening member such as a bolt. Therefore, the deformation of the front head 61 caused by the fixing does not occur. Since the deformation does not occur, it is not necessary to increase a thickness T2 with respect to a thickness T1. Therefore, the front head 61 and a discharge valve 62 are easily formed.
