RESIN PART FITTING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a resin part fitting structure in which a bolt is hardly loosened even if creep phenomena occur.SOLUTION: A reinforcement collar 4 is press fitted into a through-pass hole 3a of an oil strainer. The reinforcement collar 4 protrudes out of a protruding end of an annular protrusion part 3b. A counter-annular protrusion part 3b of a flange part 3 of the oil strainer is overlapped on a main body part 10 in such a way that an insertion hole 4a may correspond to a threaded hole 10a, a shaft part 5a of a bolt 5 is inserted into the insertion hole 4a under this state and it is threadably fitted to the threaded hole 10a. The reinforcement collar 4 is compressed and deformed by the circumferential edge of the threaded hole 10a of the main body part 10 and a head part 5b of the bolt 5 and at the same time the counter-annular protrusion part 3b is plastically deformed by the head part 5b of the bolt 5 and the oil strainer is fixed to the main body part 10.
