Patent number: 10030691Abstract: In a cable connection structure in which a roughly spherical cable end disposed at the tip of an inner wire is connected to a movable member, the movable member is provided with a pair of wing pieces that hold the inner wire, a cable insertion opening that guides the cable end to a space between the wing pieces, and a roughly elliptical cable end passage part that displaceably supports the cable end. The long axis of the roughly elliptical shape of the cable end passage part roughly coincides with the direction of insertion of the cable.Type: GrantFiled: March 23, 2012Date of Patent: July 24, 2018Assignees: ALPHA CORPORATION, NISSAN MOTOR CO., LTD.Inventors: Shuichi Kudoh, Shinji Ichikawa, Ryuichi Yoshida

Patent number: 9803402Abstract: A vehicular handle device includes: a handle base fixed to a vehicle and holding an operating handle; and a shaft component inserted into and attached to a bearing portion provided in the handle base. The shaft component is retained in the bearing portion while being restrained from moving in a slipping-out direction by a cantilever-shaped elastic piece formed on the handle base and configured to be elastically deformed to allow passage of the shaft component. The handle base is provided with a stopper protrusion portion which limits an elastic deformation range of the elastic piece by letting a free end portion of the elastic piece abut on a stopper surface.Type: GrantFiled: March 26, 2013Date of Patent: October 31, 2017Assignee: ALPHA CORPORATIONInventors: Shinji Ichikawa, Shuichi Kudoh

Publication number: 20150061304Abstract: An object of the present invention is to provide a vehicular handle device capable of preventing a fracture in an elastic piece, thereby ensuring that a shaft component 4 is prevented from coming off or becoming unmountable. Provided is a vehicular handle device including: a handle base 2 fixed to a vehicle and holding an operating handle 1; and a shaft component 4 inserted into and attached to a bearing portion 3 provided in the handle base 2. The shaft component 4 is retained in the bearing portion 3 while being restrained from moving in a slipping-out direction by a cantilever-shaped elastic piece 5 formed on the handle base 2 and configured to be elastically deformed to allow passage of the shaft component 4. The handle base 2 is provided with a stopper protrusion portion 7 which limits an elastic deformation range of the elastic piece 5 by letting a free end portion of the elastic piece 5 abut on a stopper surface 6.Type: ApplicationFiled: March 26, 2013Publication date: March 5, 2015Inventors: Shinji Ichikawa, Shuichi Kudoh
