Document Type and Number:
WIPO Patent Application WO/2015/118642
Kind Code:
A1
Abstract:
An actuator (1) is provided with: a rotating-type actuator main body (10) having an output shaft (11); an output rotator (20) that is provided at an end portion of the output shaft (11); a driven rotator (40) that is provided such that the driven rotator can rotate about a rotation axis line (CL) of the output rotator (20); an output swinger (S1), which is protruding in the outer circumferential direction from the output rotator (20), and which rotates corresponding to rotation of the output rotator (20); a driven swinger (S2), which is protruding in the outer circumferential direction from the driven rotator (40), and which rotates corresponding to rotation of the driven rotator (40); and coil springs (60, 70), which are provided between the output swinger (S1) and the driven swinger (S2), and which transmit power between the output swinger (S1) and the driven swinger (S2) by means of a repulsive force generated due to elastic deformation.
