Abstract

A valve gear is provided with a valve (12), which is formed in a gas path wall (4) configuring a gas path (5) for opening/shutting the gas path (5); and a valve seat (16) to which the valve (12) abuts. The valve seat (16) is made of a plate material or a sintered material separately from the gas path wall (4), and is fixed to a case (2) by a supporting shaft (19).
