Patent number: 11926261Abstract: In a door mirror device for a vehicle, when a driving body is moved rotationally towards an upper side, a gear plate is moved towards a lower side so that urging force applied from a coil spring to the driving body is decreased. In contrast, when the driving body is moved rotationally towards the lower side, the gear plate is moved towards the upper side so that the urging force applied from the coil spring to the driving body is increased. As a result, it is possible to reduce a difference between a load that is applied in order to move the driving body rotationally towards the upper side and the load that is applied in order to move the driving body rotationally towards the lower side.Type: GrantFiled: September 18, 2019Date of Patent: March 12, 2024Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Masahiro Kondo, Shigeki Yoshida

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
