Patent number: 9079611Abstract: A steering apparatus includes a tilt hinge shaft fixed to a vehicle body, a steering column that rotationally supports the steering shaft, and a ground clamp, which is made of an elastically deformable conductive material. The ground clamp is arranged between the tilt hinge shaft and the steering column. The ground clamp includes a second arcuate section that contacts the tilt hinge shaft, a first bent section that contacts the steering column, and a deformation section that extends between the second arcuate section and the first bent section. The deformation section is elastically deformable such that the second arcuate section and the first bent section approach each other. The ground clamp is arranged between the tilt hinge shaft and the steering column with the deformation section being elastically deformed.Type: GrantFiled: September 12, 2013Date of Patent: July 14, 2015Assignee: JTEKT CORPORATIONInventors: Yu Okumura, Yoshihide Ohara, Takeshi Kawara

Patent number: 8882148Abstract: A steering system includes a steering column which supports rotatably a steering shaft to which a steering wheel is connected and a pair of support mechanisms which support the steering column so as to tilt relative to a vehicle body. Each of the support mechanisms includes a support bracket having a column-side fastened portion and a body-side fastened portion, a fulcrum bolt, and a bush. A fastening hole through which a fastening bolt is inserted to fasten the support bracket to a fixed member is formed in the body-side fastened portion. Each of the support mechanisms includes an elastic member which can be compressed in an axial direction of the fulcrum bolt, and the support bracket is configured to oscillate relative to the steering column by the elastic member being compressed.Type: GrantFiled: January 6, 2012Date of Patent: November 11, 2014Assignees: JTEKT Corporation, Toyota Jidosha Kabushiki KaishaInventors: Yoshihide Ohara, Tatsuhiro Yamamoto, Hiroshi Kawakami, Toru Suzuki

Patent number: 8777266Abstract: First and second lower support mechanisms (27, 28): are each provided with a coil spring (66, 86) that is mated to the outer periphery of an axle part (59, 79) of a fulcrum bolt (53, 73); and are configured in such a manner that support brackets (51, 71) are able to rock with respect to a steering column (5) by compressing the coil springs (66, 86). The coil springs (66, 86) are formed in such a manner that the axle parts (59, 79) are force fitted in a state prior to column-side fastening parts (55, 75) being fastened to the steering column (5).Type: GrantFiled: January 6, 2012Date of Patent: July 15, 2014Assignee: JTEKT CorporationInventor: Yoshihide Ohara
