  • Publication number: 20180126928
    Abstract: A curvature regulation member to be inserted into a corrugated tube is made of synthetic resin, and integrally includes a belt, and a plurality of bridges standing from both ends in a width direction of the belt. The curvature regulation member is allowed to be curved in a direction that the belt is inside and the bridges are outside. In an opposite direction, curving of the curvature regulation member is restricted by the adjacent bridges abutting on each other. The bridge includes a rectangular plate. Two corners of the plate at a side away from the belt are rounded.

  • Publication number: 20160186803
    Abstract: A slide protector slidably engaged with a slide rail together with a slide support has a harness holder holding a wire harness and a hooking section capable of hooking the slide support with the harness holder and the hooking section formed integrally. Though the wire harness causes a resistance force when the slide support slides rearward in the sliding direction and the slide protector is pulled rearward, reliability of the attachment structure of the slide protector to the slide support can be enhanced since the hooking section and the harness holder holding the wire harness are formed integrally.
