ジンのオートタイマ。[Claims for Utility Model Registration] The main driving wheel 1 and the driven wheel 2 are opposed to each other with a weight movement space 3 therebetween, and a main driving post 4 protrudes from the main driving wheel 1 to the driven wheel 2 side, and from the driven wheel 2 to the main driving wheel. A compression spring 6 is interposed between the driven post 5 protruding to the 1 side to bias both posts 4 and 5 apart, and a weight 7 is pivotally supported on the driven post 5 so as to be able to swing in the centrifugal direction. A cam 8 is provided on the weight 7, and this cam 8 is slidably received on the side opposite to the compression spring of the main drive post 4, and compresses the compression spring 6 when the weight 7 moves in the centrifugal direction due to centrifugal force. and is formed so as to attract the driven post 5 and the driven wheel 2 in the advancing direction of the driving post 1 side.
In an engine autotimer, the compression spring 6 is arranged at least on one end side of two inner and outer compression coil springs 9, 10 having different initial pressures, and the initial pressure is
An autotimer for an engine, comprising disc springs 11 and 12 whose spring constant is greater than the sum of the maximum pressures of and whose spring constant is greater than the composite spring constant of both compression coil springs 9 and 10.
