Abstract: A gardening trimmer may include a first blade configured to be driven by a prime mover in a reciprocating manner along a first direction and a guide disposed in a slot of the first blade to guide reciprocating motion of the first blade. The slot includes first and second inner side surfaces opposing each other and extending along the first direction. The guide includes an outer peripheral surface opposing the slot's inner side surfaces. The outer peripheral surface of the guide includes a first portion in contact with the first inner side surface and a second portion in contact with the second inner side surface. The outer peripheral surface of the guide is curved at least at the first and second portions, and curvature radii of the first and second portions are each greater than a half of a distance between the first and second inner side surfaces.

Abstract: An electric work machine includes: a motor having a stator disposed around a rotor; a stator-holding member, which holds the stator; one or more bearings, which rotatably support(s) the rotor; and one or more bearing-retaining members, which is (are) supported by the stator-holding member in an immovable manner in the radial direction, retain(s) the bearing(s), and is (are) made of a metal. The stator-holding member is made of a material that exhibits a water-absorption coefficient of 1.5 wt % or less at equilibrium in an ambient atmosphere at a temperature of 23° C. and a relative humidity of 50%.
