Abstract
To provide a chain stop device for an electromotive chain saw that can quickly stop the rotation of a cutting chain when a trigger member is released. The electromotive chain saw is provided with a chain stop mechanism operated with a solenoid. When the trigger lever is released, the solenoid is energized, such that a brake force is applied by a chain stop mechanism. The chain stop mechanism is composed of a brake shoe for engaging with or disengaging from the inner periphery of a brake drum, a Y-shaped resilient member for supporting the brake shoe, a swingable lever for slidably guiding the resilient member, and a clutch disconnected when depressed by two arms of the resilient member.
