切離させることによって行っている。2. Description of the Prior Art Most conventional hammer drills have been capable of transmitting only "rotation and impact" or "rotation" to a tip tool. The user freely selects and switches between these two operation modes according to the work content. Explaining the power transmission path here, the rotation of the motor is the pinion, the first
The rotation is constantly transmitted to the second gear that is transmitted to the intermediate shaft via the gear and meshes with the second pinion on the intermediate shaft, and the tip tool is rotated via the cylinder. On the other hand, the sleeve, which is always in spline engagement with the intermediate shaft, and the motion converting member, which is rotatably fitted on the intermediate shaft, are engaged by the claws, and the rotation of the motor transmitted to the intermediate shaft is converted into the motion converting member. And the piston is reciprocated, the impact force is applied to the tip tool via the impact element and the intermediate element by using the air spring. Switching between these two operation modes is performed by operating a settling member connected to the outside of the housing to move the sleeve in the axial direction and disconnecting the claw engagement between the sleeve and the motion converting member.

題を有していた。The operation mode switching device for the hammer drill can freely select and switch between two operation modes. However, the main hammer drills in the past did not have a mode of "hit",
It was not suitable for "harvesting work" and the like, where only "hit" was used. Further, as described in Japanese Patent Laid-Open No. 3-504697, a hammer drill capable of freely selecting and switching among three operation modes of "rotation and striking", "rotation" only, and "striking" only has an intermediate shaft. Since the impact movement or rotation transmission to the tip tool is controlled by the axial movement of
There has been a problem that the switching device as a whole becomes large and the number of parts is large, resulting in an expensive switching device.
