Abstract
A vibration imparting device for a concrete finishing tool uses a housing having a chamber surrounded by an inner surface of the housing. A vibrator with a support, a rotor with a shaft and weighted body, a motor, and a resilient link between the shaft and the motor is positioned within the housing chamber. The vibrator also includes a resilient band to separate the vibrator from the housing inner surface. First and second adaptors are employed for the housing to be placed between the handle and the terminus of a concrete finishing tool.
