ENGAGING MEMBER

An engaging member includes an engaging portion configured to be inserted and assembled into a fixing hole of a vehicle body, an attachment portion configured to attach elongated wire routing materials, and linking portions configured to connect the engaging portion and the attachment portion to each other. The linking portions are extendable and contractable in a longitudinal direction of the wire routing materials, and can oscillate the engaging portion side in an orthogonal direction, thereby allowing the engaging portion to be movable in the longitudinal direction and the orthogonal direction. A protrusion and a through portion are provided as a movement restricting portion for restricting the movement of the engaging portion to movement within a predetermined range.
