Claims

[Scope of utility model registration request]

A transmission shaft 24 rotated by engine power transmitted via a clutch 28, an operating rod 12 inserted through the transmission shaft 24, and an operating rod 12.
A receiving member 32 is fixed to the proximal end of the clutch 28 and is inserted into the inner periphery of the receiving member 32 from the clutch 28 side so as to abut a step 36 on the back side of the inner periphery of the receiving member 32. A vibration isolator 34, a bearing case 38 that is inserted into the inner circumference of the vibration isolator 34 from the clutch 28 side so as to come into contact with the inner step 40 on the inner circumference of the vibration isolator 34, and the clutch A bearing 42 rotatably supports the connecting portion 26 between the transmission shaft 28 and the transmission shaft 24 on the inner periphery of the bearing case 38, and a bearing 42 is fixed to the end surface of the receiving member 32 and contacts the end surface of the vibration isolating material 34. A vibration isolating structure for a brush cutter, comprising a retaining member 46 that prevents the vibration isolating material 34 from coming off from the receiving member 32 by contacting the receiving member 32.
