Abstract
A driving apparatus according to an embodiment includes an arm, an operation target, and a brake unit. The arm has one end supported by a support mechanism, and includes an electric driving source. The operation target is attached to the other end of the arm, the other end being an end on the opposite side of the one end, and is enabled to be pivoted by the driving source about one rotational axis intersecting with a direction from the one end to the other end. The brake unit secures immobility of a target gear that is a gear disposed in the arm, and that is a gear being rotated as the operation target is pivoted, when the power supply to the driving source stops.

A driving apparatus comprising:
- an arm that has one end supported by a support mechanism, and that includes an electric driving source;
- an operation target that is attached to another end of the arm, the other end being an end on an opposite side of the one end, and that is enabled to be pivoted by the driving source about one rotational axis intersecting with a direction from the one end to the other end;
- and
- a brake unit that secures immobility of a target gear that is a gear disposed on the arm, and that is rotated as the operation target is pivoted, when power supply to the driving source stops.

- and
- a biasing unit that applies a biasing force to a target gear in an axial direction, the target gear being a gear disposed in the arm, and being enmeshed with a gear in a path via which driving power is communicated from the driving source to the operation target.
