PURPOSE: To stabilize fusing strength and to enhance the reliability of a fusion bonded part by grasping a tubular ends of thermoplastic resin molded products at the optimum position when the tubular ends are mutually fused.
CONSTITUTION: A fusing machine has a fixed clamp and a movable clamp 1B both of which are formed so as to be capable of grasping the tubular ends of thermoplastic resin molded products, the spacer 3 setting the interval between the tubular end grasped by the fixed clamp and the tubular end grasped by the movable clamp 11B constant and a heater 2 formed so as to be capable of heating the tubular ends. The movable clamp 1B is provided so as to be capable of moving the tubular end grasped by the fixed lamp and the tubular end grasped by the movable clamp 1B in an abutting direction. The heater 2 and the spacer 3 are arranged so as to be revolved by the same rotary shaft 11 and provided so as to be reciprocally movable between the position at the time of use and the position at the time of standby not becoming an obstacle when the tubular end grasped by the fixed clamp and the tubular end grasped by the movable clamp 1B are abutted.
