Document Type and Number:
WIPO Patent Application WO/2010/035395
Kind Code:
A1
Abstract:
An electric tool provided with a dust suction function having excellent dust suction efficiency achieved by using a simple structure for sucking dust without leaving any residue in a hose.
A fan shaft (15) rotating together with an output shaft (7) of a motor (6) and a suction fan (18) mounted on the fan shaft (15) are arranged in a dust suction chamber (11) formed in a hammer drill (1) having a dust suction function. A one-way clutch (19) is mounted between the fan shaft (15) and the suction fan (18). The one-way clutch (19) transmits rotation of the fan shaft (15) to the suction fan (18), and when the speed of the fan shaft (15) is reduced, the one-way clutch interrupts transmission of the rotation to the suction fan (18) to allow the suction fan (18) to rotate by inertia.
