    Abstract: A hand-held power tool has a power tool housing made at least partially of plastic material. A drive motor is arranged in the power tool housing and a drive shaft driven connected to the drive motor is provided. A tool member is connected to the drive shaft and driven by the drive motor through the drive shaft. A first bearing rotatably supports the drive shaft relative to the power tool housing. An intermediate element supports the first bearing relative to the power tool housing. The intermediate element is arranged in a receptacle of the power tool housing and is supported on a support surface relative to the bottom of the receptacle.
