Title:
FLUID PRESSURE TYPE OPERATING DEVICE
Document Type and Number:
Japanese Patent JPS5950207
Kind Code:
A
Abstract:
PURPOSE:To make a rigid coupling between a shaft and a movable body and improve the durability and operability of a device by a method wherein at least one reinforcing member having a larger outer shape than that of the shaft member is arranged btween a stepped part of the shaft member and a plate-like member of the movable body. CONSTITUTION:The left end of a shaft member 19 is reduced in its diameter, a reinforcing ring 13 is abutted against a stepped part 19c with a seal ring 14 being arranged therein and the ring 13 is fitted. The left end 19b of the shaft member 19 is plastically deformed with a pressure fitting and a central part 8a of a main member 8 is held between the reinforcing ring 13 and the left end 19b of the shaft member 19, thereby the movable member 30 is fixed to the shaft member 19. Since a reinforcing ring 13 is forcedly held between the stepped part 19c of the shaft member 19 and the fitted part 19b, even if the main member 8 of the movable body and the shaft member 19 are fallen or twisted, a stress applied to the fitted part 19b of the shaft member 19 may be lower than that of the convertional type.
