PROBLEM TO BE SOLVED: To provide the upside-down holding structure of a synthetic resin part to prevent the rotation of the synthetic resin part held in an upside-down state with respect to a boss part. SOLUTION: Implanting 24 with bristles is applied on the portion, making contact with the bottom 20 of at least a pin (a synthetic resin part) 19, of a synthetic resin case 2. Thus, since the bottom 20 of the pin 19 and the contact portion of the case 2 are brought into adhesion to each other through the implanting 24 with bristles, rotation of the pin 19 around the boss part 22 is prevented from occurring, the pin 19 is hardly slipped off from the boss part 22. Further, by applying the implanting 24 with bristles, even when a slight molding size error occurs to the case 2 side, the pin 19 and the case 2 are reliably adhered together through the implanting 24 with bristle.
