Abstract

A transmission driving device that is capable of preventing displacement of a shift operation member or a select operation member in a case where there is reverse input in the shift operation member or the select operation member by inhibiting rotation of a rotation member which is released from an input shaft. When an input shaft and a first rotor are connected, the first electromagnetic coil is an excitation state and a second electromagnetic coil is in a non-excitation state. In this state, a second magnetic ring is not attracted to the side of the second electromagnetic coil, a seventh facing, which is fixed to the second magnetic ring, and an eighth facing are engaged with each other, and a second rotor and a casing are connected to each other. In a connection state of the second rotor and the casing, the second rotor cannot be rotated.

A transmission driving device comprising:

a casing;
a shift operation member which is configured to perform a shift operation;
a select operation member which is configured to perform a select operation;
an input shaft to which a rotating torque of an electric motor is to be input;
a first rotation member which is configured to transmit the rotating torque to one of the shift operation member and the select operation member;
a second rotation member which is configured to transmit the rotating torque to the other of the shift operation member and the select operation member;
a clutch mechanism configured to selectively transmit the rotating torque of the input shaft to the first rotation member or the second rotation member, the clutch mechanism including:
a first clutch that is configured to connect the first rotation member to the input shaft and that is configured to release the first rotation member from the input shaft;
and a second clutch that is configured to connect the second rotation member to the input shaft and that is configured to release the second rotation member from the input shaft;
a casing side engagement portion which is provided on the casing or which is provided on a fixing member that is provided to be fixed to the casing;
and
a first engagement portion which is integrally and rotatably provided in the first rotation member, and which is provided so as to be capable of engaging with the casing side engagement portion, wherein
the first clutch is configured of an electromagnetic clutch that includes a first electromagnetic coil, and
the first engagement portion is attracted to a side of the first electromagnetic coil and the first engagement portion is engaged with the casing side engagement portion in a non-excitation state of the first electromagnetic coil in the first clutch, and an engagement between the first engagement portion and the casing side engagement portion is released in an excitation state of the first electromagnetic coil.
