Abstract
A power transmitting shaft includes a coupling member, a cylindrical intermediate member, a tube member and an increased diameter portion. The coupling member connects to a counterpart. The cylindrical intermediate member is on a side of one end of the coupling member and has a mechanical strength larger than that of the coupling member. The tube member has one end portion connected to either one of an inner circumferential portion of the intermediate member and an outer circumferential portion of the intermediate member. The increased diameter portion is on one end portion of the intermediate member which is opposed to the one end of the coupling member in an axial direction of the power transmitting shaft. The increased diameter portion is connected with the one end of the coupling member in the axial direction.
