Driving apparatus

A driving apparatus comprising:

• a first base part;
• a second base part which is surrounded by the first base part;
• a first elastic part which connects the first base part and the second base part and which has elasticity for rotating the second base part around an axis along another direction;
• a driven part which is configured to be able to rotate;
• a second elastic part which connects the second base part and the driven part and which has elasticity for rotating the driven part around an axis along one direction which is different from the another direction;
• and
• an applying part which is configured to apply, to the second base part, an excitation force for rotating the driven part such that the driven part rotates while resonating around the axis along the one direction, at a resonance frequency determined by the second elastic part and the driven part,
• the applying part being configured to apply the excitation force such that the second base part vibrates and deforms along the another direction and the deformational vibration becomes resonance,
• the resonance frequency at which the second base part resonates being determined based on a resonance frequency of the driven part,
• flexural stiffness of the second base part along the another direction becomes smaller than flexural stiffness of the second base part along the one direction.
