1. A clip comprising:
a tubular body part with an insertion hole; and elastic locking pieces, wherein the elastic locking pieces are located on the inner periphery surface of the insertion hole and on predetermined opposite areas with axis of a screw member, inserted into the insertion hole, between them, wherein each elastic locking piece extends from a first side to a second side, which is opposite to the first side, in direction of the axis such that a leading end of the elastic locking piece approaches the screw member, and wherein each elastic locking piece is elastically deformable so that the leading end separates from the screw member, each of the opposite elastic locking pieces having at the leading end a locking claw that engages a helical screw groove on the outer periphery surface of the screw member, and the locking claws being formed such that even where two or more types of screw member different in pitch of the screw groove is inserted into the insertion hole, the locking claws engage the screw groove; wherein each locking claw includes: a straight claw portion in which a claw leading-edge extends straight in a direction orthogonal to the axis; and/or a curved claw portion extending curvedly along a circumferential direction around the axis such that an extended leading edge thereof projects further toward the axis than a claw leading-edge of the straight claw portion; and wherein each of the opposite areas includes an elastic locking group consisting of one or more elastic locking pieces, wherein the elastic locking pieces belonging to the elastic locking piece group has a locking claw group consisting of at least two or more of the locking claws in total, and the locking claw group includes a combination of the locking claws in which the straight claw portion and the curved claw portion are opposite each other at least in the direction of the axis. |
