Patent 7255597 was granted and assigned to Yazaki on August, 2007 by the United States Patent and Trademark Office.
The case main body is saliently provided with an attachment bracket 65 having a screw hole 69a and the attachment bracket 65 is provided with a slit 69b communicated with the screw hole 69a and extending to the radial direction outwardly. When the wiring harness guided out from the case main body is pulled or twisted at the time of recovery of the case main body, the axial portion of a securing bolt expands the slit 69b and escapes from the slit 69b so that the attachment bracket 65 detaches from the securing bolt. A taper portion 69d is formed at the entrance side of slit 69b for guiding the penetration of the securing bolt. The slit 69b is positioned before an edge portion 69c of the attachment bracket 65.
