Power tool
First Claim
1. A power tool comprising:
- a motor having a rotational axis,a tool body that houses the motor, wherein a tool bit is coupled to a tip end region of the tool body and driven by the motor to perform a predetermined operation,a dust suction part through which dust generated during operation by the tool bit is sucked, the dust suction part covering at least a part of the tool bit,a dust transfer passage through which the dust sucked into the dust suction part is transferred, the dust transfer passage being disposed within the tool body, anda dust discharge port through which the dust transferred through the dust transfer passage is discharged to the outside, wherein the dust discharge port is disposed laterally on one side of the rotational axis of the motor and the tool bit is disposed laterally on an opposite side of the rotation axis of the motor.

Abstract
It is an object of the invention to provide an effective technique for reducing adverse effect of a dust suction device on the operability of a power tool, in the power tool which can suck dust generated during operation. The power tool has a motor 111 and a tool body 103 that houses the motor 111. A tool bit 119 is coupled to a tip end region of the tool body and driven by the motor 111 to perform a predetermined operation. The power tool further includes a dust suction part 151 through which dust generated during operation by the tool bit 119 is sucked and which covers at least a tip end of the tool bit 119, a dust transfer passage 153 through which the dust sucked into the dust suction part 151 is transferred and which is partly disposed within the tool body 103, and a dust discharge port 174 through which the dust transferred through the dust transfer passage 153 is discharged to the outside. Further, the dust discharge port 174 is disposed on the opposite side of the motor 111 from the tool bit 119.
