Power transmission apparatus

Abstract

A power transmission apparatus includes an input shaft inputting power, an output shaft outputting power, an energy storage portion arranged between the input shaft and the output shaft and configured to store energy sent from the input shaft, and a power transmission portion allowing a difference between a rotation speed of the input shaft and a rotation speed of the output shaft, the power transmission portion including a portion serving as an elastic body that is configured to store torsional deformation, the energy storage portion converting a kinetic energy into a different energy from the kinetic energy and storing the converted energy to achieve power transmission between the input shaft and the output shaft including different rotation speeds from each other.
