  • Patent number: 11255427
    Abstract: A shift device in which a press-fit column of a control lever is press-fitted into and passed through a press-fit hole in a boot such that the boot forms a seal between the upper side and the lower side of the press-fit hole. A press-fit interference amount between the press-fit column and the press-fit hole is larger at a length direction intermediate side of the press-fit hole than at a length direction end portion side of the press-fit hole. This enables a reduction in the contact force between the press-fit column and a peripheral face of the press-fit hole at the length direction intermediate side of the press-fit hole to be suppressed, enabling the sealing performance of the press-fit hole in the boot to be improved.

  • Patent number: 11181190
    Abstract: A range switching device includes a momentary selector lever movable on a shift gate, a position detector, a moving speed acquisition unit, a passage time acquisition unit, a determination time setting unit, a timing unit, and a determination unit. A neutral position determination region is disposed on a movement path between a home position determination region, a forward travel position determination region, and a reverse travel position determination region. When the selector lever moves from the forward travel position determination region toward the neutral position determination region, the passage time acquisition unit obtains an expected passage time based on a moving speed of the selector lever. The determination time setting unit sets a neutral determination time in accordance with the expected passage time. When the time measured by the timing unit reaches the neutral determination time or longer, the determination unit determines that the neutral position is selected.

  • Patent number: 8269484
    Abstract: An inductance-type rotation angle sensor includes: a stator formed by printing an annularly formed magnetic conductor and a receiving conductor placed adjacent to the magnetic conductor on a glass-epoxy-resin substrate; and a rotor having an excitation conductor attached thereto in a manner opposing the magnetic conductor. In the sensor, a thermosetting-resin covering layer, which is connected together through a periphery of the substrate and a through-hole included in this substrate, is formed on both front and back surfaces of the substrate by molding; a portion of the covering layer covering the magnetic conductor and the receiving conductor is formed as a thin thickness part which is thinner in thickness than a remaining portion of the covering layer; and the stator is buried in a thermoplastic-resin control housing with the thin thickness part being exposed to an outside.
