That is, when a current flows through the second shape memory alloy wire 23c, the second slide drum 23b slides upward because it is heated and contracts instantaneously. Then, since the upper right outer peripheral end of the second slide drum 23b contacts and presses the operating piece 26a of the micro switch 26, the micro switch 26 is turned on, and the current flowing through the second shape memory alloy wire 23c is reduced. Will be blocked. As a result, the current flowing through the second shape memory alloy wire 23c can be saved in about 1/10 second.
When the second slide drum 23b moves up, the wire 23a suspended on the second slide drum 23b is pulled to rotate the claw member 21d (see FIG. 9) in the direction opposite to the previous direction. The claw member 21d operated in this way holds its rotating position by the urging means 27a, so even if the wire 23a is loosened by the operation of the micro switch 26 after the operation, it will automatically return to its original position. Never come back.

  As shown in FIG. 9, the first claw member 21d is urged to rotate in one direction between the locking pin 21r attached to the claw member 21d and the locking pin 21q attached to the support shaft 21c. Biasing means 27a made of a tension coil spring is stretched. In this case, since the position of the locking pin 21q is shifted from the center with respect to the support shaft 21c, the claw member 21d is rotated once regardless of which direction the left and right directions are rotated by the wire 21e and the wire 23a. Thereafter, the urging means 27a holds the rotational position as described above. When the claw member 21d rotates with respect to the gear 21a when the gear 21a rotates in the auto-lock direction, the claw member 21d prevents the rotation by causing the claw portion 21n to bite into the tooth portion 21b of the gear 21a. In the reverse rotation direction, the arrangement relationship is determined so as not to prevent the rotation of the gear 21a.

Further, as shown in FIG. 9, the gear 21a is provided with rotation detecting means 35 on the outer periphery thereof. The rotation detection means 35 is a rotation angle detection sensor composed of, for example, an optical sensor.

The end 6i of the holding member 6f provided in the holding means 6 holds the tire of the wheel 9 from both sides so that the wheel 9 does not leave.
Therefore, even if the motorcycle 8 is to be lifted upward in this state, the wheel 9 is not detached from the front wheel rear portion holding means 6 because the holding member 6f holds the tire of the wheel 9 from both sides. As a result, the motorcycle 8 cannot be delivered.

When the motorcycle 8 that has entered the warehouse is to be delivered, for example, an operation for depositing a fee to the fee settlement apparatus corresponding to the bicycle parking apparatus 1 is performed. In response to this, the actuator 23e side of the actuator activation circuit is turned on, a current flows through the second shape memory alloy wire 23c, and the form of the second shape memory alloy wire 23c changes and contracts. Thereby, the claw member 21d rotates counterclockwise via the wire 23a, and the engagement state with the gear 21a is released, so that the front wheel rear portion holding means 6 is allowed to be reversed.
As a result, the locked state with respect to the wheels 9 of the motorcycle 8 is released, and the wheels 9 of the motorcycle 8 can be moved backward.
When the wheel 9 of the motorcycle 8 moves backward, the front wheel rear portion holding means 6 rotates, for example, counterclockwise in FIG. 1 (B) to reach the warehousing standby position as shown in FIG. 1 (A). . Further, as the wheel 9 of the motorcycle 8 moves backward, the holding member 6f that holds the wheel 9 from both sides at the position shown in FIG. 6 (B) rotates to the position shown in FIG. 5 (B). Thus, the holding of the wheel 9 is released. As a result, the motorcycle can be delivered.
