Patent number: 11878731Abstract: A switch device includes a switch body, which is attached to and rotated integrally with an irregularly-shaped steering unit, and a lever unit, which is held pivotally about a switch body. The lever unit includes a lever shaft including a base, which extends in a direction intersecting the steering shaft, and an arm, which is formed integrally with the base and extends in a direction that differs from the direction in which the base extends. The lever unit also includes a lever head at the distal end of the lever shaft, and the lever head extends from the lever shaft in the width direction, which intersects an axial direction.Type: GrantFiled: March 1, 2021Date of Patent: January 23, 2024Assignees: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masahiro Kato, Nobuyuki Ishigure, Yuki Sato, Tadashi Usuya, Takayuki Aoki, Shinji Matsubara, Toshihiko Kosugi, Ryusuke Ohta, Shinji Hara

Patent number: 11673597Abstract: A switch device includes a switch body, which is arranged at the back side of a steering unit, and a lever unit, which is attached to the switch body to allow for switching by a pivotal operation about a first axis, which extends in the axial direction of a steering shaft. The lever unit includes a lever shaft, which extends in a direction intersecting the first axis of the pivotal operation, a lever head, which is arranged at the distal end of the lever shaft and has a larger dimension than the diameter of the lever shaft, and a push operation unit, which allows for switching by a push operation. The push operation unit is arranged so that the operation direction of the push operation is directed toward the first axis.Type: GrantFiled: March 1, 2021Date of Patent: June 13, 2023Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Nobuyuki Ishigure, Yuki Sato, Tadashi Usuya, Akio Nishiyama, Masahiro Kato, Takayuki Aoki, Shinji Matsubara, Toshihiko Kosugi, Ryusuke Ohta, Shinji Hara
