Patent number: 9457675Abstract: An actuator containing a drive mechanism that moves a locking pin forward and backward. Said drive mechanism is provided with the following: a holder that holds the locking pin; a cam member that has a cam gear; and a power-transmitting member in which a lower gear to which power from a motor is transmitted and an upper gear coupled to the cam gear are formed. The cam is offset from the center of rotation of the cam gear. The holder is pushed in a forward/backward direction by reciprocal motion of the cam within a range that constitutes less than a full revolution about the center of rotation of the cam gear. A region into which part of the lower gear fits and a region through which the cam moves are provided in a space above one surface of the cam gear.Type: GrantFiled: December 11, 2013Date of Patent: October 4, 2016Assignee: MURAKAMI CORPORATIONInventors: Akira Fukai, Hiroya Miwa

Publication number: 20120314425Abstract: A turn lamp unit has a substrate holding unit for use when assembling a rigid substrate equipped with a lamp to a base member. This substrate holding unit comprises a board-like substrate mount rising from a bottom face on the inner face side of the base member; a pair of elastic pressers, which rise from a flat part of the substrate mount and are arranged so as to oppose each other in a width direction of the base member (i.e., a vertical direction in the state where the turn lamp unit is mounted to a door mirror), for pressing the front face of the rigid substrate by elasticity and thereby holding the rigid substrate at the substrate mount; and a projection, disposed on the substrate mount between the pair of elastic pressers, for abutting against the rear face of the rigid substrate.Type: ApplicationFiled: May 29, 2012Publication date: December 13, 2012Applicant: MURAKAMI CORPORATIONInventors: Akira FUKAI, Hiroya MIWA, Ryo INUZUKA

Patent number: 8215781Abstract: In a mirror for an automobile, the adoption of resin mirror body to a mirror plate can decrease the weight of the mirror body, and the mirror plate is fixed onto a mirror holder through the welding. Therefore, this eliminates the usage of both-sided adhesive tape or adhesive agent, makes assembly processes less complicated, and thus the reduction in production cost is achieved. Furthermore, since the mirror plate can be fixed onto the mirror holder firmly and strongly even when the mirror plate is not pressed strongly to the mirror holder, excessive load on the mirror holder or the mirror plate becomes avoided. In addition, at the time of the production stage, some dimensional variation in the edge part of the mirror holder or the peripheral edge of the mirror plate becomes easily acceptable.Type: GrantFiled: November 17, 2009Date of Patent: July 10, 2012Assignee: Murakami CorporationInventors: Fumitaka Kitagawa, Akira Fukai
