Abstract
A boss is provided around the periphery of a bushing that is penetrated by a shaft, which moves inside the bushing in the axial direction of the shaft. The boss retains the bushing and the shaft moving inside the bushing, and has a heat conductivity that is higher than that of the bushing. An air gap is provided between the bushing and the boss.
Claims7
A heat resistant structure for a shaft retainer, the structure comprising:
