Abstract
A gear mechanism including: a pair of housings that are combined in a positioned state by mating a cylindrical inner surface and a cylindrical outer surface centered on a first axis with each other; two first gears that are attached to one housing so as to be rotatable about the first axis and a second axis parallel to the first axis; and two second gears that are rotatably attached to the other housing, and that are respectively engaged with the two first gears in a state in which the pair of housings are combined. The first gear that is attached so as to be rotatable about the second axis and the second gear that is engaged with the first gear are arranged at positions where an inter-axial distance therebetween is changed by means of a relative rotation of the housings about the first axis.
