Title:
刈払機
Document Type and Number:
Japanese Patent JP4341804
Kind Code:
B2
Abstract:
When the number of rotations of a drive source (21) has fallen below a predetermined value, clutch moving members (45; 85) are disengaged from a clutch drum (31; 81) by clutch resilient members (46), and thus the clutch drum (31; 81) is caused, by a braking resilient member (36), to resiliently slide back to a predetermined braking position where a brake shoe (33; 83) is pressed against brake pads (35) to apply the brakes. When the number of rotations of the source unit (21) has increased above a predetermined value, the clutch moving members (45; 85) are caused to slide radially outward by centrifugal force in such a manner that the clutch moving members (45; 85) press and axially slide the clutch drum (31; 81) to a non-braking position against the bias of the braking resilient member (36), so that the brake shoe (33; 83) is disengaged from the brake pads (35) to release the brakes.
