摘要：
A leaf seal as a shaft seal mechanism is made compact and enables reduction of manufacturing cost. Plural thin plates 29 lapped one on another in layers have their outer circumferential proximal ends fixed to each other by welding so that an annular thin plate assembly 29A having flexibility is formed. This thin plate assembly 29A is bent and assembled to form the leaf seal 25.
