Abstract: A housing structure includes first and second housings and first and second rotation transmitting members. The first and second housings house a shaft. The first rotation transmitting member is provided coaxially with the shaft. The second rotation transmitting member is arranged so as to transmit power to the first rotation transmitting member. The first and second housings are combined with each other so that mating surfaces of the first and second housings that are unparallel to an axis of the shaft are contacted. The first housing includes a first guide portion that protrudes from the mating surface of the first housing. The second housing includes a second guide portion that engages with the first guide portion. The first and second guide portions are engaged with each other along a circumferential direction of the axis and guide relative rotation of the first housing and the second housing around the axis.
