Patent number: 11410822Abstract: Embodiments disclosed herein describe a base, an operation unit that moves in a contacting/separating direction with respect to the base in response to an external force, and a pair of link members turnably coupled to each other by a coupling portion and configured to guide movement of the operation unit in the contacting/separating direction. The pair of link members includes a first curved portion and a second curved portion that are supported on the base, and a first rotary spindle and a second rotary spindle that are supported on the operation unit. When the operation unit moves in the contacting/separating direction with respect to the base, the first curved portion and the second curved portion slide with respect to the base in a direction substantially perpendicular to the contacting/separating direction and in a direction substantially perpendicular to a turning shaft of the pair of link members.Type: GrantFiled: April 13, 2017Date of Patent: August 9, 2022Assignee: Omron CorporationInventors: Kazuhira Izawa, Hiroaki Fujino, Mamiko Naka, Kenshi Nagata
