を特徴とスルチェーンソーのブレーキ装置。A cam plate is formed to rotate the hand guard and control a spindle that drives the chain blade, and includes a cam plate fixed to the rotating shaft of the hand guard, and a cam plate rotatably attached to one end and free at the other end. The end of the cam plate engages with the free end of the cam plate and is biased in the direction of rotating the cam plate to the inoperative position via a movable pin drive spring attached to the rotation support shaft, thereby braking the set plate. A hook plate having a hook portion that locks in the release position, and one end of a set plate that is rotatably mounted and is movable in a direction perpendicular to the axis of the spindle and has a lower end that can be locked to a protrusion of a stop collar. A movable pin is provided with an engagement groove into which the hand guard is inserted and aligned, and the end portion is rotationally driven by the free end of the cam plate to move the movable pin in the brake release direction in conjunction with the rotation of the hand guard in the brake release direction. When the hand guard is rotated in the braking direction, the hook plate is rotated and the hook portion is locked at the position where it engages with the hook portion of the hook plate. The set plate is formed such that when the movable pin drive spring is released, it is pressed by an end of the movable pin drive spring opposite to the hook plate rotation drive side end, thereby driving the movable pin in the braking direction. ,
A brake device for a chain saw, comprising: a spring clutch brake device having the stop collar attached to the spindle.
