ABSTRACT:
A centrifugal spark-advance controlling device has a weight being subjected to centrifugal force caused by the revolution of a driving shaft to be opened against the elastic force of a spring member to thereby advance an advancing sleeve with respect to the driving shaft. There are base plate fixed to the driving shaft, the base plate being provided with an elongated groove for guiding which serves as a guide for the weight to be moved in the direction of opening and an advancing plate fixed to the advancing sleeve, the advancing plate being provided with an elongated groove for advancing which determines a relative advance angle of the advancing sleeve with respect to the driving shaft in association with the elongated groove for guiding. The weight is placed between the base plate and the advancing sleeve and there are provided on the base plate a cylindrical projection for guiding which is inserted into the elongated groove for guiding to be engaged therewith and a cylindrical projection for advancing which is inserted into the elongated groove for advancing to be engaged therewith.
