Abstract: The present invention simplifies the processing of flanges that are to be integrated with a base part of a robot device and makes it possible to use a small number of adapter components to connect a plurality of corresponding decelerators to the processed flanges. A robot device that comprises a base part that houses decelerators that drive a first arm and a second arm that have a parallel link. The robot device comprises two first decelerators that are arranged on either side of the first arm so as to be parallel and drive the first arm, a second decelerator that is arranged so as to be parallel to the two first decelerators and drives the second arm, two first adaptor components that are respectively arranged between the base part and the two first decelerators and connect the base part and the first decelerators, and a second adapter component that is arranged between the base part and the second decelerator and connects the base part and the second decelerator.

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.

Abstract: Provided is a rotational-force transmitting part including: a rotation support member that is supported, with respect to a first member, so as to be rotatable about a predetermined axis by means of a bearing and that is provided with a first fitting surface formed of a cylindrical outer surface or a cylindrical inner surface centered on the axis; a rotational-force transmitting member that transmits a rotational force with respect to a second member and that is provided with a second fitting surface to be fitted onto the first fitting surface; an annular elastic member that is disposed at such a position as to seal a space between the first fitting surface and the second fitting surface; and a fixing member that fixes the rotational-force transmitting member and the rotation support member in a state in which the first fitting surface and the second fitting surface are fitted.

Abstract: A robot that enables a stopper to be installed even when it is difficult to allow a space for providing the stopper. The robot includes a first component; a second component movably coupled to the first component; a first stopper provided on one of the first component and the second component, the first stopper extending along an axis parallel to a movement direction of the second component relative to the first component; and a second stopper provided on the other of the first component and the second component, the second stopper configured to come into contact with the first stopper when the second component moves relative to the first component and limit a movement range of the second component relative to the first component.
