PROBLEM TO BE SOLVED: To provide a power transmission mechanism in which the engine speed of an output shaft can be changed to the number of the rotation of a pulley without using the inhalation negative pressure of an internal combustion engine.SOLUTION: A power transmission mechanism (60) includes a pulley (100), an input shaft (110), an electric motor (120) rotating the input shaft, an annular gear (130) arranged in the pulley to have the same rotation center as the rotation center (180) of the pulley, a planet gear (140), an axial branch member (150) which axially supports the planet gear so that, while transmitting the rotation of an input shaft to the planet gear, the planet gear to which the rotation of the input shaft is transmitted while meshing with the annular gear rotates relatively to the annular gear in an eccentric state to the rotation center of the annular gear, and an output shaft (160) which has the same rotation center as the rotation center of the pulley, and an adjustable joint (170) which transmits the rotation of planet gear to the output shaft. |
