る。Is Figure 1 a conventional centrifugal crane? 2 is a sectional view of the road body showing the main parts of Fig. 1, Fig. 3 is a front view of the main parts of the centrifugal clutch device according to the present invention, and Fig. 4 is a plan view of Fig. 3. 5 is a cross-sectional view taken along the line A-A in FIG. 4, and FIG. 6 is a cross-sectional view showing the operating state.
is a drive shaft, 14 and 15 are clutch pieces, 14a and 15a are engagement projections, 17 is a clutch member, 17a and 17b are locking pins as locking projections, 18 and 19 are springs as resilient members, 20 is a motor pulley as a driven member.

Claims

[Claims for Utility Model Registration] A drive shaft that is rotationally driven; a clutch holder that is fixed to the drive shaft and that is integrally driven to rotate; and a clutch holder that is pivotally supported at an appropriately eccentric position so as to be swingable by centrifugal force. , a pair of clutch pieces each having a locking protrusion at its base end, and a resilient member formed by connecting the tip of one clutch piece and the base end of the other clutch piece to each other; a clutch member provided with a pair of locking protrusions having one side as a driving surface and the opposite side as a non-driving surface with respect to the rotational direction of the drive shaft; and a fixed driven member, and when the rotation speed of the drive shaft reaches a predetermined rotation range, the tip of the clutch piece is swung in a centrifugal direction against the elastic force of the elastic member. At this time, the one engagement protrusion engages with the one locking protrusion, and the other engagement protrusion engages with the non-driving surface of the other locking protrusion, thereby causing the clutch piece to engage with the clutch member. A centrifugal clutch device is characterized in that the rotational driving force of a drive shaft is transmitted to a driven member by connecting the two in a locked state.
