  • Patent number: 6852065
    Abstract: Because a shift lever device 10 uses attracting force of a fixed iron core 150A, 216A of a magnet 150 or an electromagnet 216 in switching between a lock state and an unlock state at a shift lock mechanism 118 and a key interlock mechanism 200, the mechanisms can be made compact. When a shift lever 12 is changed from a “D” shift position to a “4” shift position and when the shift lever 12 is changed from a “2” shift position to an “L” shift position, a link 30 is rotated in a same direction. Thus, a sliding direction of a slider 38 which detects a rotational position of the link 30 is only one, and a placement size of a detecting member 48 can be made small and the device can be made compact. Because the shift lock unit 88 is equipped integrally with shift lock mechanism 118, and the link 30, the slider 38 and the detecting member 48 of a sensing mechanism, the shift lock unit 88 can be made compact.
