ABSTRACT:
An automatic canceling device for a winker which comprises a container, a winker operation lever rockably held in the container, an engaging unit extensibly or contractibly provided through a compression spring mounted in the lever, a locking cam provided in the container for holding the lever engaged with the engaging unit at neutral, right or left positions, a solenoid energized by an unlock signal, an unlocking member for rotating the lever in the unlocking direction in contact with the second cam unit provided on the lever, and an energizing member engaged with the unlocking member for energizing the locking cam toward its neutral position. Thus, the automatic canceling device can hold the compression spring at a neutral position without fluctuation even if the spring tension of the spring is small, and reduce the size and the cost of the solenoid by reducing the operating force in case of unlocking.
