PROBLEM TO BE SOLVED: To provide a fusion device which can be miniaturized and can enhance fusion quality. SOLUTION: The fusion device is constituted so as to mutually fuse a fuel tank main body 1 formed of a thermoplastic synthetic resin material and a daughter part 3 and has the linear slide actuator (10) for a tank heating plate and a linear slide actuator (9) for the daughter part both of which are provided on a base supported so as to be revolvable around a predetermined axis by a rotary actuator (5), the tank heating plate (12) supported on the propelling axial line of the linear slide actuator (10) for the tank heating plate and the heating plate (7) for daughter part provided at the position capable of being aligned with the propelling axial line of the linear slide actuator (9) for the daughter part. By this constitution, since the heating plates for fusing two parts can be individuated, temperatures can be controlled independently corresponding to the heat capacities of two parts. Further, since the propelling axes of the linear sliding actuators can be aligned with the axial line of the heating plate, the inclination of a heating surface due to the effect of bending can be excluded.
