<p>PROBLEM TO BE SOLVED: To provide a combining structure for parts that can combine parts together with a simple structure and can reduce assembly time by press fitting or molding a first protrusion of a lock pin in one part, forming a driving hole for the first protrusion in the other part, overlapping the one part on the other part and driving a second protrusion in the extraction hole of the first protrusion of the one part. SOLUTION: A first protrusion of each lock pin 19 is placed in a press fitting slit hole 18f of a lock member 18 by press fitting it or molding it after insertion. Each fitting recessed part 18b is fitted in a small diameter stepped part 7e of a rotor 7, the lock member 18 is overlapped on the rotor 7 and the lock pin 19 is driven with a hammer jig, so that the first protrusion is extracted from the slit hole 18f and is driven into a slit hole 7g of the rotor 7. At the same time, a second protrusion of the lock pin 19 is driven into the slit hole 18f and thus, the lock member 18 and the rotor 7 are combined by the lock pin 19. Since the second protrusion of the lock pin 19 is larger than the first protrusion, the combining force is not reduced even if the second protrusion is driven into the extraction hole 18f of the first protrusion.</p> |
