Patent number: 10794106Abstract: A wire type window regulator for vehicle that allows easily guiding a drive wire to a wire insertion clearance of a wire guide member and/or a drum housing during assembly is obtained. A wire guide member includes a wire guide groove around which the drive wire is wound, a wire disconnection prevention portion, and an inclination guide surface. The wire disconnection prevention portion is disposed to extend from one region to another region of regions on both sides between which the wire guide groove is interposed. The wire disconnection prevention portion forms a wire insertion clearance from which the drive wire is introducible to the wire guide groove with the other region. The inclination guide surface is disposed in the other region. The inclination guide surface guides the drive wire introduced to the wire guide groove to the wire insertion clearance.Type: GrantFiled: March 21, 2017Date of Patent: October 6, 2020Assignee: SHIROKI CORPORATIONInventors: Atsushi Muramatsu, Toru Ikoma, Yoshiki Sugita

Patent number: 10626656Abstract: An assembling determination method and an assembling determination device for a vehicular opening-closing body driving device can determine a normal/abnormal winding of a drive wire around a spiral groove to ensure a quick and accurate action. The assembling determination method includes winding a drive wire around the spiral groove on the peripheral surface of a drive drum, wherein the drive wire drives a vehicular opening-closing body, arranging an inspection jig to face the drive drum surface via a clearance, determining that the drive wire is wound around the spiral groove in an abnormal manner when the inspection jig contacts the drive wire, and determining that the drive wire to be wound around the spiral groove in a normal manner when the inspection jig and the drive wire are contactless.Type: GrantFiled: March 21, 2017Date of Patent: April 21, 2020Assignee: SHIROKI CORPORATIONInventors: Atsushi Muramatsu, Toru Ikoma, Yoshiki Sugita, Kimihiro Kinoshita

Publication number: 20190085613Abstract: A driving device for a vehicular opening-closing body that ensures stably assembling a drum housing and a motor unit without requiring high positioning accuracy is provided. One of the drum housing and the motor unit includes a plurality of boss portions projecting toward another one of the drum housing and the motor unit, and securing members for securing the drum housing and the motor unit are secured to the plurality of boss portions. The other one of the drum housing and the motor unit includes a plurality of boss receiving portions that receive the plurality of boss portions. At least one of the plurality of boss receiving portions has a reverse tapered surface that has a diameter expanded toward a corresponding boss portion. In a state where the drum housing and the motor unit are supported, a clearance is disposed between the boss portion and the reverse tapered surface.Type: ApplicationFiled: March 21, 2017Publication date: March 21, 2019Applicant: SHIROKI CORPORATIONInventors: Atsushi MURAMATSU, Yoshiki SUGITA, Toru IKOMA
