<P>PROBLEM TO BE SOLVED: To provide an assembly manufacturing method in which components are assembled to each other while suppressing backlash. <P>SOLUTION: The method for manufacturing an assembly 100 is configured as follows. A locking claw 41 provided on a fastening member 40 is inserted into a locking hole 21 provided in a non-fastening member 20 so as to lock the locking claw to the locking hole 21. Consequently, the fastening member 40 is assembled to the non-fastening member 20, thereby manufacturing the assembly. The inner-peripheral wall surface 24a of the locking hole 21 and the outer-peripheral wall surface 44a of the locking claw 41 are formed of materials having deflection temperatures under load different from each other. The inner-peripheral wall surface 24a formed of a PC resin having a higher deflection temperature under load is provided with a protrusion 25 protruding toward the outer-peripheral wall surface 44a formed of an ABS resin having a lower deflection temperature under load. The locking claw 41 is locked to the locking hole 21 so as to bring the protrusion 25 into contact with the outer-peripheral wall surface 44a. In that state, the temperature of the outer-peripheral wall surface 44a is raised so as to form a complementary recess 45, having a shape for complementing the protrusion 25, on the outer-peripheral wall surface 44a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
