The blush plate 17 is made of resin. A blush holder 72, in which a through hole 72e is formed, for holding the blush 21, and a pair of pop-out restriction walls 61 and 62 for restricting the movement of the spring holder 63, which closes an end of the through hole 72e of the blush holder 72, in a longitudinal direction of the blush holder 72 are integrally formed in the blush plate 17.
