Abstract: A quick connector includes a tubular socket, a wire retainer attached to an outer circumferential surface of the socket, and a guide member provided inside of the socket. The wire retainer has a lock portion which engages with a flange of a first tubular body when the guide member is at a second position. An outer circumferential surface of the guide member is formed with a holding recess in which the lock portion is fitted when the guide member is at a first position, and a wall of a pair of walls forming the holding recess is formed with a tapered guide surface that extends radially outward. The tapered guide surface guides the wire retainer so that the wire retainer goes over the flange when the first tubular body is inserted.

Abstract: A lock device includes lock portions, a pair of rods, a base member, a rotary member, and a manipulation member. The rotary member has a rod link portion coupled with the rods and transmit rotational power of the rotary member to the rods and a guide wall located inside the rod link portion in the rotary member and guides the rods. The guide wall includes arc walls or a cylindrical wall whose axis coincides with the rotation center of the rotary member. When viewed from a direction perpendicular to a bottom surface of the base member, the erection wall and the guide wall are opposed to each other with a gap. Coming-off-preventive structures for preventing the rod from coming off when the rod is inserted in the gap and coupled with the rod link portion is provided between the rod and the erection wall.
