| 摘要 |
The present invention relates to an internal combustion engine starting apparatus, wherein between the first pulley (22) fitted on the output shaft (21) of the direct current motor (20) for driving the internal combustion engine (100) and the second pulley (11) fitted on the crankshaft (10) of the internal combustion engine (100), the belt (40), which is power transmission means to transmit the driving power of the direct current motor (20) to the crankshaft (10) of the internal combustion engine (100), is installed. Between the output shaft (21) of the direct current motor (20) and the first pulley (22), the lift off type one-way cam clutch (23), wherein the cam (23a) lifts off by the centrifugal force causing release of the power transmission engagement between the inner element (23c) and the outer element (23b), is provided. <IMAGE> |
