By operating in the front-rear direction, the lever 16 is slid in the front-rear direction while the guide portion 16B is slid in the front-rear direction along the slide plate 14A, and the shift position of the lever 16 is changed. Furthermore, when the sensor substrate 30 detects the sliding position of the lever 16 in the front-rear direction of the magnet 28, the sliding position of the lever 16 in the front-rear direction is detected. Further, the check pin 24 of the lever 16 is brought into contact with the moderation surface 14C of the housing gate 14 (check portion 14B) by the urging force of the check spring 26 of the lever 16, so that the lever 16 is urged to the “H” position side. The

  Here, when the lever 16 is slid in the front-rear direction, the roller 20 is rotated by contact with the slide plate 14A. Therefore, the sliding resistance between the lever 16 (guide portion 16B) and the slide plate 14A can be reduced, the sliding resistance of the lever 16 in the front-rear direction can be reduced, and the sliding performance of the lever 16 in the front-rear direction is improved. it can.

  A magnet 28 is provided at the lower end of the lever 16. For this reason, unlike the case where the magnet 28 is provided on the interlocking member that is interlocked with the sliding movement of the lever 16 in the front-rear direction, the accuracy of the position of the magnet 28 relative to the sliding position of the lever 16 in the front-rear direction can be increased. The detection accuracy by the sensor substrate 30 of the slide position in the front-rear direction can be improved. In addition, it is possible to eliminate the need to provide the interlocking member, and to reduce the number of parts.

  Further, when an overload (impact) is input to the lever 16, the guide portion 16B can interfere with the housing gate 14 in the entire radial direction around the front-rear direction (the sliding direction of the lever 16), and the guide portion. 16B can interfere with the front wall (front part) of the housing gate 14 on the front side, and the guide part 16B can interfere with the rear wall (rear part) of the plate 12 on the rear side. For this reason, the overload input to the lever 16 can be received by the housing gate 14 and the plate 12 via the guide portion 16B in all directions (entire direction in which the lever 16 is movable).

  Further, the check spring 26 urges the lever 16 downward (plate 12 side), so that the bottom wall of the retainer 18 abuts the bottom surface of the urging hole 16D at the lower position of the guide portion 16B of the lever 16. Has been. For this reason, when a downward load is applied to the knob 16E of the lever 16 by the occupant, it is possible to suppress rattling to the lower side of the lever 16.
