Abstract
An electrically powered garden tool includes an electric motor mounted upright within an outer shell housing, a pair of relatively reciprocating shear blades assembled to be driven by operation of the motor through a crank mechanism provided within a lower portion of the outer shell housing, and a cooling fan assembled to be driven by operation of the motor for introducing outside air into an upper portion of the outer shell housing to exhaust the introduced air from a lower portion of the outer shell housing. In the garden tool, a downward exhaust opening is formed within a lower end peripheral wall of the outer shell housing enclosing the crank mechanism such that the air spouted by rotation of the cooling fan blows out downward from the downward exhaust opening to restrain the occurrence of blowing noise of the air.
