According to this assembly structure, in FIG. 10, the accommodating hole 10 of the case 9 has an elastic urging member 12 including a guide pin 14 and a coil spring 15, and a lock groove formed in a part of an inner wall of the accommodating hole 10. Lock piece 20 engageable with 19
And are housed. According to this structure, the lock piece 20
Although one end of the coil is engaged with the lock groove 19 to be prevented from being pulled out, the lock piece 20 and the guide pin 14 which are separate bodies must be inserted into the accommodation hole 10 while compressing the coil spring 15, respectively. Since the spring 15 urges the lock piece 20 and the guide pin 14 in the direction of pushing the lock piece 20 and the guide pin 14 from each other, the assembling is extremely difficult and requires skill and time.
