- the clockwise turning of the lever 172d causes the switch lever 172b to be inserted into the hollow part of the lever 172d in the direction shown at the arrow m at the same time of biasing the torsion spring 172h downwards.
- the torsion spring 172h presses down the switch button 172j of the first switch 172i, so that the turning-on state of the seventh solenoid 213 is continued.
- the timing sensor disc 172 is designed such that one revolution thereof causes each of the conveyor belts 104a and 104b to move in a distance corresponding to a width of an automobile to be parked. Thus, one revolution of the timing sensor disc 172 achieves the automatic conveyance of the automobile by the distance corresponding to the width of the automobile.
