ABSTRACT:
A brake device disposed in the vicinity of a clutch drum has a leaf spring having a brake pad thereon which is brought into slidable contact with the clutch drum. A cam member and a compression coil spring which opposes a cam member with the leaf spring disposed therebetween are provided on a free end of the leaf spring. The cam member is rotated by a rotatable shaft together with a pinion gear which meshes with a rack formed on a stand. When a trimmer is placed on the ground, the stand is moved upwardly and the brake pad is brought into the braking position where the brake pad slidably contacts with the clutch drum. This braking position is released when an operation lever is operated by an operator.
