A portable compass saw which is provided with an oscillation drive for driving a saw blade. The oscillation drive includes a gear, which is mounted on a shaft in the housing; engaging in the teeth of the gear is a pinion of a drive shaft of a drive motor. At a distance from its axis of rotation, the gear is provided with a pin extending parallel thereto. The pin is in driving connection with a clutch member, which is connected to the push rod and has a guide for the bolt, with the guide extending at right angles to the longitudinal axis of the push rod. The teeth of the gear are provided on that side of the gear which faces the push rod. The pinion is located in the region between the push rod and the gear, which is seated loosely on the shaft and is held on the latter under the load of the pinion. As a result, the gear is held reliably in its installed position, even though it is seated loosely on the shaft and is not secured to prevent axial displacement by separate securing members. |
