ABSTRACT:
Each of paired centrifugal weights are interlockingly connected to an advancing spring, which is interlockingly connected to a temperature-sensing operation device. When cold-starting the engine, the advancing spring is maintained extensible based on a state of the temperature-sensing operation in which the temperature-sensing operation device senses a temperature to operate. This advancing spring exerts a spring force, which pushes and widens the paired centrifugal weights to an advancing position. While the engine is warm, the advancing spring is held contracted based on another state of the temperature-sensing operation device, in which the temperature-sensing operation device senses a temperature to operate, so that the spring force of the advancing spring does not act on the paired centrifugal weights. A shape memory spring composed of a compression coil spring is used for the temperature-sensing operation device.
