Patent number: 9364968Abstract: 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.Type: GrantFiled: August 25, 2014Date of Patent: June 14, 2016Assignee: MAKITA CORPORATIONInventor: Satoshi Takahashi
