  • Patent number: 8729993
    Abstract: In a solenoid, a coil is energized in a state where movement of a plunger toward the inside of a yoke is stopped. Accordingly, when the coil is energized, it suffice that movement of the plunger toward the outside of the yoke is inhibited by a magnetic force, and it is not necessary to move the plunger into the yoke by the magnetic force. Therefore, it is not necessary that a force moving the plunger toward the inside of the yoke is increased by a conventional core. Accordingly, the conventional core is not assembled in a frame, so that number of components can be decreased so as to reduce the cost.

  • Patent number: 8726755
    Abstract: In a shift lever device, a first-link is held at a permitting-position due to a release button being operated. Therefore, when a shift lever is operated from a “P” shift position, when a second-link is pushed toward a vehicle right side by the shift lever, even if a magnet is not energized, the second-link is rotated in a state where sliding of the first-link toward a vehicle right is impeded. Operation of the shift lever from the “P” shift position is thereby forcibly permitted. Here, the first-link is disposed at the permitting-position that is an initial-position, and, due to the release button being operated, the first-link is held at the permitting-position. Therefore, there is no need to move the first-link by operation of the release button, and the operation load and operation stroke of the release button can be made to be small.

  • Patent number: 8613236
    Abstract: In a shift lever device, even when a magnet is immovably installed, the shift lever device can shift a shift lever between blocking and allowing operation from a “P” shift position to an “R” shift position because a first link and a yoke plate are slidable, a second link is rotatable with respect to the first link, and the magnet switches between attraction and non-attraction with respect to the yoke plate. For this reason, the magnet can be immovably installed.

  • Publication number: 20120260760
    Abstract: In a joystick device where a tilting operation direction of an operation shaft is detected based on positional change of a magnet relative to a magnetic sensor, the magnet being moved with tilting of the operation shaft, a slider is arranged between a base facing a board fixed to a case and a magnet holder to which the operation shaft is swingably coupled; the magnet holder is joined to the slider such that the slider guides relative movement of the holder in a first linear direction orthogonal to the axis of the operation shaft but prevents relative movement of the holder in a second linear direction orthogonal to the first direction; and a guide mechanism configured to guide movement of the slider in the second direction is provided between the slider and the base. This prevents variation in the detection accuracy regardless of tilting of the shaft.
