VALVE FASTENING STRUCTURE

摘要

A valve (30) has pin press fitting holes (32, 33) which pass from front to back through a valve shaft insertion hole (31). A valve shaft (20) has a pin press fitting hole (21) that cause the valve shaft (20) to be coaxial with the pin press fitting holes (32, 33) when inserted in the valve shaft insertion hole (31). A pin (40) is press fitted into the pin press fitting holes (32, 21) from the front side of the valve (30), and a pin (41) is press fitted into the pin press fitting holes (33, 21) from the back side, thereby fastening the valve (30) and the valve shaft (20).
