Title:
ELECTRIC ACTUATOR FOR PARKING LOCK DEVICE
Document Type and Number:
Japanese Patent JP2008174190
Kind Code:
A
Abstract:
To reduce an operation load necessary when an electric actuator is manually driven.
In the electric actuator 4, the inertia of an armature 47 is set to 2 kgfm2 or less, and the armature 47 is rotatably supported by bearings 45, 46. A core 50 is skewed, and grooves 57A are cut on the outer peripheral faces of core teeth 57. Pressing force of a spring 55 for pressing a brush 53 is set to be 300 gf or less, and an eccentric magnet 48 forms a magnetic circuit. By reducing friction of a motor 42, the operation load necessary when a rod 92 is manually advanced/retracted is reduced.
