Claims

[Claims for Utility Model Registration] 1. A nozzle head having a jet port connected to a working fluid supply source formed on the tip surface is projected and fixed to a base, and a driven member such as a cutter is fixed integrally. A rocking body is integrally fixed to the drive shaft, the rocking body having a pressure receiving recess formed in a protruding end that opens corresponding to the jet nozzle of the nozzle head to freely rotate. The oscillating body is held in a standby position in which the tip of the nozzle head is inserted into the pressure-receiving recess with a slight gap and without rubbing against each other by the bias of the return spring, and the jet orifice is closed. It is characterized by a configuration in which a jetting pressure of the working fluid acting from the outlet into the pressure receiving recess applies a rotational force to the swinging body in the standby position in a direction to swing against the biasing force of the return spring. Oscillating actuator. 2. The protruding end of the nozzle head is faced and the rocking body is accommodated in the accommodation space formed in the base body, and the rocking body is brought into contact with the base body by a surface of the rocking body opposite to the pressure receiving recess. A stopper is provided to prevent the movable body from swinging in a direction that opposes the biasing force of the return spring, and a communication hole is formed on the surface of the stopper that contacts the swinging body to communicate the accommodation space with the outside of the base body. A swing actuator according to claim 1 of the utility model registration claim, characterized in that:
