    Abstract: A work of incorporating a speed reduction mechanism including a scissors gear into a gear case is facilitated. In a state where the angular positions of gear teeth of a first gear and the angular positions of gear teeth of a scissors gear are made to coincide with each other against the elastic force of a torsion spring (19), these angular positions are fixed by a fixing member (position fixing step). The first gear, the scissors gear, and a second gear are housed in a gear case, and the gear teeth of the second gear are made to engage with the gear teeth of the first gear and the gear teeth of the scissors gear (gear incorporating step). The fixing of the angular position of the first gear and the angular position of the scissors gear by the fixing member is released through an opening formed in the gear case.

    Abstract: Disclosed herein is a rotation transmitting device which permits the transmission of rotation with a reduced play and which permits the constituents to be aligned easily. The rotation transmitting device has a transmitting member (30) which surrounds a rotating part (12) of a drive shaft (11) and a rotating part (22) of a driven shaft (21). At least either the rotating part (12) of the drive shaft (11) or the rotating part (22) of the driven shaft (21) has an external surface that comes into contact with the internal surface of the transmitting member (30) so that friction arising between the internal surface and the external surface achieves torque transmission and reception to and from the transmitting member (30).

    Abstract: Without an increase in the cost, a movable range is defined. A first joint mechanism includes a base part, and a rotary part that rotates relatively to the base part. The first joint mechanism includes a regulated part that rotates together with the rotary part, a regulating part that is disposed on the extension of the rotation locus of the regulated part, and that has a function of regulating rotation of the regulated part relative to the base part, within a first movable range, and a movable range defining member that is disposed on either the base part or the rotary part, and that defines, as a movable range of the regulated part, a second movable range that is narrower than the first movable range.
