Abstract: A working machine may include: a working part; a prime mover configured to drive the working part; a housing supporting the working part; a handle attached to the housing such that the handle is rotatable about a rotation axis with respect to the housing and configured to be grasped by a user; and an elastic member arranged between the housing and the handle. The housing may comprise a first surface. The handle may include a second surface that faces the first surface in a rotation axis direction with an interval therebetween. The elastic member may be arranged between the first surface and the second surface.

Abstract: To provide a chain tension adjustment device for a chain saw. When a first mechanism is rotated around an axis, a bevel gear of a second mechanism is engaged with a bevel gear of the first mechanism and rotated, and a bevel gear of a third mechanism is engaged with the other bevel gear of the second mechanism, so that a shaft portion is rotated. A plate portion integrated with a nut portion of a fourth mechanism screwed on a screw formed on the shaft portion moves in an axial direction, and a guide bar engaged with an engagement portion of the plate portion via an engagement hole moves in a longitudinal direction, to adjust tension of the chain saw by adjusting the movement amount. Thus, fine adjustment can be performed while reducing an operating force, and reducing the weight and the cost.

Abstract: A backpack type assembly may include a backpack type carrier configured to be worn by a user and a device configured to be attached to the backpack type carrier. The backpack type carrier may include a pair of shoulder straps configured to be worn on both shoulders of the user, a back plate to which the pair of shoulder straps and the device are attached, a waist belt configured to be wrapped around a waist of the user, and a connection mechanism configured to connect between the back plate and the waist belt. The connection mechanism may include an elastic member having a flexural rigidity smaller than a flexural rigidity of the back plate. A force applied to the connection mechanism from one of the back plate and the waist belt may be transmitted through the elastic member to the other of the back plate and the waist belt.

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.
