Abstract

PURPOSE: To obtain a heat machine in which the fixing condition of a pin member can be ensured while the machine is in operation and the pin can be readily replaced, by inserting the pin member formed of a material having a thermal expansion coefficient larger than that of the machine actuating part into a hole formed in said actuating part.
CONSTITUTION: A pilot pin 14 is formed from a pilot part 18, an insertion part 19 and a fixing part 20, which is constituted by fixing, in a screwing manner, a cylindrical fixing tube 21 around a shaft 20' having a small diameter. The fixing tube 21 is formed of a material having a thermal expansion coefficient larger than that of a cavity unit 11, and the outside diameter thereof at ordinary room temperature is to be slightly smaller than the inside diameter of a pin mounting hole 17.
