Abstract
The present invention relates to improvements in a switch for a direction indicator suitable for use in a motor car comprising: a bracket operationally associated with a control lever for a direction indicator and rotatable through a predetermined angle in dependence on a direction indicated; a rachet opposed to the main body of the bracket through a steering wheel, opposite end portions of which are constantly biased in a direction of being engaged with opposite end portions of the main body of the bracket, and rotatable through a predetermined angle in dependence on a direction indicator; and a cancel cam formed at the periphery thereof with projections capable of releasing a condition of engagement between the end portions of the main body of the bracket in response to the rotation of the steering wheel in a state of having a slight clearance in the direction of rotation and rotatable along with the steering wheel. Striking noises occurring during operation of a steering wheel are prevented by: a frictional inclusion interposed between abutting surfaces of the cancel cam and the steering wheel; shock absorbing means provided between abutting surface of the bracket and the ratchet; a lubricant of high viscosity filled in recesses formed on a shock receiving surface of either the bracket or the ratchet; shock absorbing members provided at portions of engagement between the steering wheel and the cancel cam for absorbing clearances in the direction of rotation; and shock absorbing tongues integrally formed either on the end portions of the main body of the ratchet.
