  • Patent number: 11920951
    Abstract: Provided is a photoelectric sensor capable of being securely joined to a housing while being sufficiently resistant to dirt. A housing 12 of a photoelectric sensor 10 has an opening 121 which allows passage of at least one of light from a light projecting unit 14 and light to a light receiving unit 16, and is provided with a cover lens 50 which covers the opening 121 and is optically transmissive. The cover lens 50 is joined to an edge portion 121a of the housing 12 defining the opening 121. An outer surface 51 of the cover lens 50 is provided with antifouling coating 61. An inner surface 52 of the cover lens 50 has a joint portion 52a which is in contact with the edge portion 121a and is not provided with the antifouling coating 61.

  • Patent number: 10921843
    Abstract: This accelerator pedal device includes a pedal arm having an accelerator pedal, a housing that supports the pedal arm so as to be capable of swinging about a prescribed axis line between a rest position and a maximum push position, a slider that slides over an inner wall of the housing, a contact part formed on the pedal arm in order to exert pressing force while separably coining into contact with the slider, and an urging spring disposed between the housing and the slider so that the urging force pressing the slider against the inner wall and the contact part increases in accordance with the pushing of the accelerator pedal.

  • Patent number: 10739810
    Abstract: This accelerator pedal device is provided with a pedal arm having an accelerator pedal, a housing that swingably supports the pedal arm, a slider that slides over the inner wall of the housing and that is pressed by the depressing of the accelerator pedal, a hysteresis-causing mechanism that includes a biasing spring for exerting biasing force through the slider so as to push back the pedal arm with and that causes hysteresis in the depressing force, and a return spring that exerts biasing force directly on the pedal arm in order to return the pedal arm to a rest position, the biasing spring and the return spring being disposed in the same area inside the housing.
