PROBLEM TO BE SOLVED: To provide a decompression component of a decompression device which improves the strength and the manufacturing efficiency etc.SOLUTION: A decompression device 10 is provided at an end part of a cam shaft 1 of a valve gear and opens a valve of the valve gear to decompress a combustion chamber of an engine when the engine is started. In the decompression device 10, a decompression cam 11, which is a component of the decompression device 10, includes: a decompression shaft 12; and a mass weight 13 which is coupled to the decompression shaft 12 and rotates the decompression shaft 12 by effect of a centrifugal force resulting from rotations of the cam shaft 1. The mass weight 13 is formed by a lamination body 24 formed by laminating multiple steel plates 21, 22, 23. |
