PROBLEM TO BE SOLVED: To provide a small-sized displacement magnifying mechanism, having a high resonance frequency, which is capable of obtaining a large displacement. SOLUTION: A displacement enlarging mechanism has a first arm 22 supported on a supporting member 20 through a first resilient portion 18 at a base end side thereof, a second arm 26 supported on a supporting member 20 through a second resilient portion 24 at a base end side thereof, a connecting member 28 connecting the first arm 22 and the second arm 26, and an actuator which is capable of exerting a predetermined pressing force to the first arm 22. The first resilient portion 18 and the second resilient portion 24 are relatively different in shape from each other.
