  • Patent number: 10301857
    Abstract: In a push-button switch device for a vehicle including a case fixed to a vehicle body or a lid openably and closably mounted on the vehicle body, a push-button that forms a housing chamber in cooperation with the case and supported on the case configured for a pushing operation, and a switch housed in and fixed to the housing chamber for changing a switching mode thereof in response to a pushing operation of the push-button, a through passage is formed in the case, the through passage having one end part thereof communicating with the housing chamber, and an air vent hole is provided in the case, the air vent hole providing communication between the other end part of the through passage and the outer panel. Such configuration prevents water from entering a housing chamber thereby avoiding deterioration of the push-button, and enabling the housing chamber to breath.

  • Patent number: 9865412
    Abstract: In a push-button switch device for a vehicle including a first case member fixed to a vehicle body or a lid openably and closably mounted on the vehicle body, a second case member mounted on the first case member forming a case together with the first case member, a push-button supported on the case configured for a pushing operation, and a switch housed in and fixed to the case in a state in which waterproofness is ensured while a switching mode thereof is changed in response to a pushing operation of the push-button, the entrance of water into the case is suppressed as far as possible. A labyrinth passage bent up and down is formed between the first and second case members further inside than an abutment part formed by mutual abutment of at least upper edges among peripheral edges of the first and second case members.

  • Patent number: 9422753
    Abstract: A vehicular electric lock device is provided in which a magnet is provided in a slider which is operated linearly in response to rotation of an electric motor and is operatively linked to a lock member, and a magnetic sensor detects by means of a magnetic field of the magnet that the lock member is in at least one of a lock position and a unlock position, wherein the slider comprises a screw-fitting member that is formed from a ferromagnetic material having rigidity and has a threaded shaft screwed thereinto and a magnet retaining member that is formed from a paramagnetic material, covers the screw-fitting member and retains the magnet, and the magnet retaining member is coupled to the screw-fitting member while preventing a relative movement in the direction along an axis of the threaded shaft and relative rotation around the axis of the threaded shaft.

This enables the size to be reduced and the position of a lock member to be accurately detected.
