Abstract
A power transmission apparatus includes a first/second/third rotary shaft, and a positioning member. The first rotary shaft is connected to an output shaft of a drive source. The second rotary shaft is spline-fitted to a rotary shaft of an electric motor. The third rotary shaft is connected to the first rotary shaft and the second rotary shaft. The positioning member is configured to apply an elastic force in a rotational direction to the rotary shaft and the second rotary shaft in a portion where the rotary shaft and the second rotary shaft overlap each other; set each of a position in the rotational direction of a spline of the rotary shaft of the electric motor and a spline of the second rotary shaft to a specified position, and applies the elastic force in the rotational direction to the rotary shaft and the second rotary shaft.
