According to the present invention, there is provided an automatic rotating-type turret device for work machinery, in which a lift-type turret is not used. The configuration makes it possible for a clutch device to lock a turret using one drive device (actuator), and generates a wedge effect, thereby obviating the need for a large driving force capable of directly countering a load during cutting operation. The turret can even be locked using air or a small driving force generated by a motor and obviates the need for hydraulics. The automatic rotating-type turret device for work machinery is provided with an axial-direction slide body 7, which is advanced or retracted in the direction of the axis of rotation of the turret 3 by the drive device 5 advancing or retracting the drive body 6 in a direction orthogonal to the direction of rotation axis; and a clutch device 4 that is engaged or disengaged by the axial-direction slide body 7 being advanced or retracted, the turret 3 being of a non-lift-type, and there being provided to the drive body 6 a tapering action part 8 for generating an expanding action caused by the movement of the drive body 6 and pressingly sliding the axial-direction slide body 7 against the turret stage 1.
