Claims

[Scope of utility model registration request]

an upper case, a lower case, a diaphragm whose outer periphery is held between the opening edges of both cases, an elastic means interposed between the diaphragm and the upper case, and the lower case. and a rod that is inserted into a central hole and has one end attached to the diaphragm, and the rod makes reciprocating motion including yawing. An actuator characterized by being provided with a shaft guide formed to have approximately the same diameter as the inner diameter of a central hole of a case.
