Abstract
The present invention provides a spring mechanism which can elastically deform an elastic deformation part with a film shape of a transducer into a shape having high symmetry, and also can be structured in a small size. A spring mechanism 2 includes: a cylindrical member 7 that is provided so as to extend toward a first element member 21 from an elastic deformation part 11 of a transducer 5, and also is arranged so as to slidably penetrate the first element member 21 in the direction of a central axis line C of the elastic deformation part 11; and a rod member 32 that is provided so as to extend toward the cylindrical member 7 from a second element member 22 side, and is slidably inserted in the cylindrical member 7 in the direction of the central axis line C of the elastic deformation part 11.
