    摘要： A grounding body may be mounted on a cutting blade shaft of a grass cutter. The grounding body may include a mounting part for mounting the grounding body on the cutting blade shaft, wherein a cutting blade is mounted on the cutting blade shaft to be positioned above the grounding body; and a main body coupled to the mounting part and configured to contact a ground. The main body may include a first main body constituted of a first resin; and a second main body constituted of a second resin different from the first resin.

    摘要： 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.

    摘要： A gardening trimmer may include: a conversion mechanism for converting rotational motion of a prime mover to linear motion along a first direction; a blade for moving in reciprocating motion relative to a guide bar and including a plurality of slots; and a plurality of guide members each disposed in a corresponding slot of the plurality of slots of the blade. The plurality of slots may include: at least one first slot in which a corresponding guide member of the guide members that is connected to a housing is disposed. A combination of the slots and the guide members may include: a first combination to reduce frictional resistance generated by the reciprocating motion; and a second combination to reduce vibration generated by the reciprocating motion, and at least one combination of the at least one first slot and its corresponding guide member is the second combination.

    摘要： A working machine may include: a conversion mechanism configured to convert motion of a prime mover; a first blade connected to the conversion mechanism; a second blade overlapping with the first blade in an up-down direction and facing a first facing surface of the first blade; a sealing member engaged with a first non-facing surface of the first blade that is opposite to the first facing surface, wherein the sealing member includes a first sealing surface facing the first non-facing surface in the up-down direction; and a cover member facing a second sealing surface of the sealing member that is opposite to the first sealing surface of the sealing member. The sealing member may be disposed forward of the conversion mechanism and configured to suppress the object cut with the first blade and the second blade from moving toward the conversion mechanism between the first blade and the cover member.

    摘要： 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.
