Abstract
An automatic cancelling device for electric-type blinkers comprises: a case; a blinker operation lever pivotably connected to the case about an axis; an engagement rod slidably disposed on the blinker operation lever and biased in a direction away from the axis by a compression spring; a lane-change cam rigidly connected to the case and positioned to contact the engagement rod, the lane-change cam having an stepped portion for creating a clicking feeling at a right and a left position to which the blinker operation lever swings; a locking protrusion provided on the blinker operation lever; a locking member adapted to engage the locking protrusion so as to lock the blinker operation lever at its right or left position and capable of moving toward and away from the locking protrusion; and a locking-member driving member which moves the locking member so as to effect engagement and disengagement between the locking member and the locking protrusion. The detention cam and the locking members are formed as separate members, with the displacement of the locking member, effected by the locking-member driving member, being made relatively small.
