However, the electromagnet holding member 30 may hold the electromagnet 10 with a gap in order to absorb and adhere to variations in the face-to-face contact between the suction plate 20 and the electromagnet 10 (in the illustrated example, the suction plate holding member 40 is The case where the suction plate 20 is held with a gap is shown). Hereinafter, in the embodiment of the present invention, the case where the suction plate holding member 40 holds the suction plate 20 with a gap will be described as an example.

The electromagnet 10 is not energized at all times, and is energized only when a shift lever (not shown) is shifted to the P (parking) position, the ignition switch is turned on, and the foot brake is depressed. As shown in FIG. 1, the electromagnet 10 attracts the attracting plate 20 when energized.
The adsorption plate 20 can be adsorbed to and released from the electromagnet 10. The suction plate 20 is held by the suction plate holding member 40 with a gap. As shown in FIGS. 4 and 10, the suction plate 20 has an insertion portion 21 that is inserted into the insertion hole 41 a of the suction plate holding member 40.

The electromagnet holding member 30 is an electromagnet holding portion 31 that holds the electromagnet 10 without backlash. The electromagnet holding member 30 includes a boss 32 for connecting to the link 60.

As shown in FIG. 1, the suction plate holding member 40 is attached to the case 80 so as to be rotatable around the same axis P <b> 1 as the axis P <b> 1 of the electromagnet holding member 30. The suction plate holding member 40 is in the position of FIG. 1 when the shift lever is in the P position.
The suction plate holding member 40 is urged to rotate in the direction C in FIG. 1 by an urging member (not shown) with respect to the case 80. The biasing force of the biasing member is set to be weaker than the attractive force of the electromagnet 10.
As shown in FIGS. 4 to 6, the suction plate holding member 40 includes a suction plate holding portion 41 that holds the suction plate 20 with backlash, and a stopper portion 42 that can come into contact with a shift lever (not shown).

The suction plate holding portion 41 has an insertion hole 41 a into which the insertion portion 21 of the suction plate 20 is inserted and a claw portion 41 b that holds the lower end portion of the suction plate 20. The suction plate holding portion 41 is provided with a cushion material 43 that presses the suction plate 20 from the back side of the suction plate 20 to the claw portion 41b and the edge of the insertion hole 41a.
When the shift lever is shifted from the P position to the R (P select) position when the electromagnet 10 is not energized, the stopper portion 42 hits a part of the shift lever. Since a part of the shift lever comes into contact with the stopper portion 42, the shift lever cannot be operated to the R (P select) position (shift lock state).
