Kind Code:
A1
Abstract:
[Problem] To provide a power transmission mechanism that comprises a reverse brake and can temporarily release that reverse brake. [Solution] This power transmission mechanism 20 is provided with a rotation prevention and release section in which: a line L1 that joins a central axis 21 of a reference gear member 40 and a first axis 44 of a first planetary gear member 42 and a line L2 that joins the central axis 21 of the reference gear member 40 and a second axis 47 of a second planetary gear member 45 form a prescribed angle α; when a first carrier member 22 and a second carrier member 32 have been rotated relatively in directions so as to narrow the prescribed angle α, rotation in one direction is prevented; and, when the first carrier member 22 and the second carrier member 32 have been rotated relatively in directions so as to widen the prescribed angle α, the rotation-preventing state is released.
