Claims

[Claims for Utility Model Registration] 1. Regarding the clutch plate that rotates integrally with the drive shaft,
A cam ball is sandwiched between a pair of cam plates to perform a driving operation that presses a friction plate that can rotate integrally with the cutting blade mounting part, and a braking operation that presses the friction plate with an immovable brake plate. In a clutch device for a power lawn mower that is selectively operated in conjunction with the rotational operation of an actuator, the first pressure spring presses the friction plate and the clutch plate together, and the brake plate and the friction plate are pressed together. A clutch device for a power lawn mower, characterized in that a second pressurizing spring is disposed facing each other in a state of being elastically deformed in the axial direction. 2. The above-mentioned practical application in which the brake plate extends from the cam plate of the actuator, and the second pressure spring is interposed between the cam plate and a locking member that prevents rotation of the cam plate. A clutch device for a power lawn mower as claimed in claim 1. 3. The mowing blade attachment portion and the actuator are rotatably attached via bearings to a sleeve fitted into the drive shaft so as to be able to rotate integrally with the drive shaft, and the clutch plate is provided integrally with the sleeve. A clutch device for a power lawn mower according to claim 1 of the registered utility model claim.
