A gardening trimmer may include: a first blade; a facing member overlapping with the first blade in a second direction perpendicular to a first direction; and a suppressing structure. Grease may be applied to at least a part of a conversion mechanism. The first blade may include: a plurality of first slots; and a plurality of pairs of first connecting portions, wherein each pair of the first connecting portions is disposed at opposite ends of corresponding one of the first slots in a third direction perpendicular to the first and second directions. The suppressing structure may be configured to suppress the grease from moving toward a front end of the first blade in the first direction. The suppressing structure may be disposed on the facing member at a position facing at least one pair of in the second direction when the first blade reciprocates relative to the facing member.

Gardening trimmer

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.

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.
