Abstract
A portable power blower includes a body and a handle mounted on a top of the body. The body includes a prime mover, a fan volute chamber, a fan housed in the fan volute chamber and attached to one end of an output shaft of the prime mover, and an air inlet of the fan volute chamber formed in front of the fan. A main guard member is so mounted as to cover one side surface of the fan volute chamber on which the air inlet is formed, and a gap for radially introducing external air into the air inlet is formed between a rear side of the main guard member and the one side surface. The gap is in open communication with atmosphere at a top portion of the body. A bottom guard member connected to the main guard member and the fan volute chamber covers bottom portions of the fan volute chamber and the prime mover, and a sub-guard member connected to the bottom guard member and the fan volute chamber covers sides of the prime mover which oppose the main guard member and the bottom guard member, respectively.
