Abstract
A retainer is inserted and fitted into an engagement hole that is open in a first direction of a housing where the first direction, a second direction, and a third direction are defined as mutually-orthogonal three directions. An engagement portion is disposed at each of a pair of inner wall surfaces facing each other in the second direction in an inner peripheral wall of the engagement hole. The retainer includes a pair of first outer surfaces facing each other in the first direction, a pair of second outer surfaces facing each other in the second direction, and a pair of third outer surfaces facing each other in the third direction. A long hole passing through the third outer surface in the third direction is formed so as to be adjacent to each of the second outer surfaces, and extends in the first direction defined as a longitudinal direction. A beam portion supported at both ends by a pair of longitudinal-direction end portions is formed between the long hole and the second outer surface. An engagement projection that engages with the engagement portion is formed at an intermediate portion in the longitudinal direction of the beam portion. A stress relaxation structure that relaxes stress acting on the intermediate portion of the beam portion includes a hole expanding portion that expands at least one of the pair of longitudinal-direction end portions of the long hole in a lateral direction.
