Patent number: 11920674Abstract: In this shift device, in a case in which an external force has acted on a lever when an operating mechanism is causing the lever to pivot, a clutch mechanism permits rotation of a first detent plate with respect to a second detent plate, such that pivoting of the lever is permitted. Note that a restraining mechanism urges the lever toward a shift position. This enables to the restraining mechanism to urge the lever separately to the clutch mechanism, thereby enabling the degrees of freedom for setting a biasing load on the lever by the restraining mechanism to be increased.Type: GrantFiled: March 18, 2022Date of Patent: March 5, 2024Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Tomonori Hayase, Koji Imai, Tomoaki Asai, Kota Nishida, Yohei Nakano, Yosuke Murakami, Munetoshi Makimura
