Abstract
An electric power blower (,) includes a handle (,) mounting therein a disk-shaped speed change dial (,) which is capable of rotation on a shaft (,). The speed change dial (,) is disposed between a speed change switch (,) and a trigger switch (,) and has a cut-out (,) formed therein through which the trigger switch (,) can pass without interference, depending on the rotational position of the dial (,). The speed change dial (,) includes a stopper (,) at an free end which defines the cut-out (,). A first regulating surface (,) and a second regulating surface (,) are provided on the stopper (,), forming an angled corner therebetween. The peripheral surface of the speed change dial (,) is exposed to the outside of the blower (,) through two windows (,) in both sides of the handle (,) adjacent to the trigger switch (,) so as to allow manual rotation. The amount by which the trigger switch (,) is pulled into the handle is determined by the rotational position of the speed change dial (,).
