Abstract: A mist blower may include: a liquid tank configured to store liquid; a fan; an ejection tube through which air delivered by the fan flows; a liquid nozzle body disposed inside the ejection tube and configured to inject the liquid stored in the liquid tank into the ejection tube; and a facing body being away from the liquid nozzle body. The liquid nozzle body may comprise: a liquid passage through which the liquid flows and which comprises a constricted part having a minimum diameter; and a nozzle side surface along which air delivered by the fan flows. The liquid may be ejected from an ejection hole of the constricted part. The facing body may comprise: a facing surface that faces the ejection hole; and a facing body side surface connected to the facing surface and along which air delivered by the fan flows.

Abstract: A working machine may include: a first blade; a second blade overlapping with the first blade in an up-down direction; and a holding unit configured to hold the first blade and the second blade overlapping each other in the up-down direction. The first blade may be configured to reciprocate in a direction perpendicular to the up-down direction with respect to the second blade. The first blade may include a first elongated hole having a longitudinal direction along the reciprocating direction. The second blade may include a second elongated hole having a longitudinal direction along the reciprocating direction. The holding unit may include: a holding part inserted in the first elongated hole of the first blade and the second elongated hole of the second blade; and an outer sleeve having a cylindrical shape and supported by the holding part such that the outer sleeve is rotatable around the holding part.

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: The first opening part penetrates the first partition wall that separates the crank chamber and the oil sump chamber. The lubricating device of the engine includes an oil mist generation control part. The oil mist generation control part disperses gas injected from the crank chamber into the oil sump chamber through the first opening part when the crank chamber has a positive pressure or restricts the flow of oil with which the injected gas collides, thereby controlling an amount of oil mist generated in the oil sump chamber.

Abstract: A power-operated work apparatus has a machine body which includes an electrostatic charge inducing member that may induce electrostatic charges thereon, and is adapted to be used with the machine body maintained electrically ungrounded. The work apparatus includes: a grip which is adapted to be grasped and held by a user and has an outer surface to be touched by the user and an inner surface forming an inner space; an electroconductive body member which forms an electroconductive body exposed on at least a part of the outer surface of the grip; and an electroconductive line member which is configured to be charged with the electrostatic charges induced on the electrostatic charge inducing member and has a part disposed inside the grip neighboring to and without electrically touching the electroconductive body forming member. The electrostatic charges are to spark from the electroconductive line member to the electroconductive body member.
