|1. (WO2014203899) PARKING DEVICE|
|Applicants:||AISIN AW CO., LTD.
A hydraulic unit (30) and an electromagnetic unit (50) are disposed in directions orthogonal to each other. Furthermore, the electromagnetic unit (50) is configured such that: when a current is being passed through a coil (64), a solenoid shaft (52) is held (i.e. movement thereof towards a right side in the accompanying figure is restricted); and, during movement of a piston rod (32) when a current is not being passed through the coil (64), the solenoid shaft (52) is allowed to move towards the right side in the figure. In a parking-lock release state, when hydraulic pressure applied to a piston (38) is reduced as a result of not passing a current through the coil (64), a roller (48) of a pin (46) of the piston rod (32) comes into contact with a tip (54) of the solenoid shaft (52), thereby causing the solenoid shaft (52) to move towards the right side in the figure as the piston rod (32) moves downwards in the figure, and switching into a parking locked state.
