Patent number: 10458537Abstract: In a shift lever device, a lever moves an operation member when the lever is rotationally operated in a front-rear direction, and the lever rotates a select link such that the select link moves the operation member when the lever is rotation operated in a left-right direction. The position of the operation member is detected to detect a shift position of the lever. When the lever is rotation operated in the front-rear direction, the lever therefore moves the operation member without being through the select link, thereby enabling the precision with which the shift position of the lever in the front-rear direction is detected to be raised.Type: GrantFiled: July 24, 2017Date of Patent: October 29, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Takehiro Niwa, Yohei Nakano, Naomi Asahina

Patent number: 10428932Abstract: At a shift lever device, a shift lever is supported at a retainer due to the shift lever being inserted into the retainer from an upper side portion, and select shafts of the shift lever being inserted into select frames of the retainer. Here, at the select shafts, amounts of projection of circular shafts and intermediate shafts are small as compared with amounts of projection of plate shafts. At a time when the select shafts are inserted into the select frames, the circular shafts and intermediate shafts can pass supporting pillars of the select frames, and an angle of tilting of the shift lever with respect to the retainer in a left-right direction can be made to be small. Therefore, a left-right direction dimension of the retainer can be made to be small, and the shift lever device can be made to be compact in the left-right direction.Type: GrantFiled: June 8, 2015Date of Patent: October 1, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventor: Takehiro Niwa

Patent number: 10253870Abstract: In a shift lever device, a gate pin of a lever is guided by a gate groove of a gate plate, and a detent pin of the lever is abutted on a detent face of a detent block due to an urging force. A sensor mechanism detects a shift position of the lever. The gate plate, the detent block, and the sensor mechanism are disposed at a lower side of the lever, the gate plate and the detent block are disposed at a rear side of the lever, and the sensor mechanism is disposed at a front side of the gate plate and the detent block. This thereby enables a reduction in size of the shift lever device in an up-down direction.Type: GrantFiled: July 24, 2017Date of Patent: April 9, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-DEISAKUSHOInventors: Takehiro Niwa, Yohei Nakano, Naomi Asahina

Patent number: 9939060Abstract: In a shift lever device, at a time when a shift lever is pivotally operated in a front-rear direction, a retainer and a link are pivoted integrally with the shift lever, and a pivot portion is pivoted in the front-rear direction. Further, at a time when the shift lever is pivotally operated in a left-right direction, the shift lever is pivoted with respect to the retainer, and the link is pivoted, and the pivot portion is thereby pivoted in the left-right direction. Moreover, a position of the pivot portion is detected by a detecting mechanism, and a shift position of the shift lever is detected. Therefore, the shift position of the shift lever can be detected via the link.Type: GrantFiled: October 14, 2014Date of Patent: April 10, 2018Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Daisuke Kato, Wataru Yumoto, Reiji Higuchi, Takehiro Niwa

Publication number: 20140033849Abstract: A shift device provided with a shift lever that is movable from a home position to a plurality of mode selection positions including a travel mode selection position and a non-travel mode selection position. A lever holding mechanism holds the shift lever at the travel mode selection position when the shift lever is moved to the travel mode selection position and returns the shift lever from the non-travel mode selection position to the home position when the shift lever is moved to the non-travel mode selection position.Type: ApplicationFiled: July 29, 2013Publication date: February 6, 2014Applicant: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Makoto YAMAMOTO, Katsushi MIWA, Yohei NAKANO, Takehiro NIWA, Hironori WATANABE, Naomi ASAHINA
