Patent number: 9714048Abstract: A fastening mechanism fastens a first side plate to a second side plate by a fastening member. A boss with a rhombic cross-section of the fastening member is inserted into a telescopic-adjust long groove of the second side plate. An outer periphery of the boss includes a first corner part and a third corner part each forming an obtuse angle and facing each other. The first corner part is disposed on an upper side in an axial direction, on a lower side in a tilt direction, while the third corner part is disposed on a lower side in the axial direction, on an upper side in the tilt direction. A width across the first corner part and the third corner part is shorter than a groove width W of the telescopic-adjust long groove.Type: GrantFiled: April 18, 2016Date of Patent: July 25, 2017Assignees: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Susumu Imagaki, Atsushi Tano, Kentaro Kikuiri, Shunsuke Nunomura, Yuuji Ishii, Hiroshi Kawakami

Patent number: 9511792Abstract: A resin pin which is passed through a first resin-pin passing hole of a first plate, and a second resin-pin passing hole of a second plate to couple the second plate to a predetermined position of the first plate is sheared in a secondary collision, and causes the second plate to release from the predetermined position in a column movement direction. A slide plate which extends along the upper surface of the first plate has a resin-pin visual check hole. A highly hard collar is received by the second plate, placed in the first resin-pin passing hole, and fitted to a shaft portion of the resin pin. In the resin pin, axial elastic projections which apply a pressing and urging force to the slide plate are disposed at positions avoiding a range where, in a secondary collision, the resin-pin visual check hole is passed in the column movement direction.Type: GrantFiled: July 17, 2014Date of Patent: December 6, 2016Assignees: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Eiji Tanaka, Susumu Magaki, Shigeru Hoshino, Shunsuke Nunomura

Patent number: 9359002Abstract: A steering device includes a fixed bracket which includes a first plate, a movable jacket which rotatably supports a steering shaft, a movable bracket which includes a second plate, a suspension mechanism and a resin pin. The suspension mechanism includes a suspension shaft connecting the first plate and the second plate, and is configured to move in a column movement direction along with the second plate at the time of the secondary collision. The resin pin is inserted into a first hole provided in the first plate and a second hole provided in the second plate, and is configured to be broken at the time of the secondary collision. The resin pin has a predetermined amount of play in a direction orthogonal to the column movement direction with respect to at least one of the first hole and the second hole.Type: GrantFiled: July 14, 2015Date of Patent: June 7, 2016Assignees: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Eiji Tanaka, Hiroyuki Yao, Shunsuke Nunomura, Yoshito Fujita
