A robot according to embodiments includes a first link (14b), a second link (14c), an actuator (Mf), a scissors gear (43, 143), and a support part (72). The second link (14c) is rotatably connected to the first link (14b). The actuator (Mf) drives the second link (14c) in a rotatable manner. The scissors gear (43, 143) includes a main gear (44, 144) and a sub gear (45, 145), and outputs driving force from the actuator (Mf) to the second link (14c). The support part (72) is attached to the first link (14b) and rotatably supports the scissors gear (43, 143). Furthermore, the scissors gear (43, 143) includes a spring (46, 146) that is arranged adjacent to the support part (72) in the direction of the rotational axis (43c, 143c) of the scissors gear (43, 143) and applies biasing force to the main gear (44, 144) and the sub gear (45, 145) in rotational directions different from each other. |
