 | | Disclosed is an electric power tool having a gear mechanism, which reduces a noise by absorbing collision of gears and is resistible to a high torque. |
 | | Moreover, even if the precision of the gear is improved, there has been a problem of deterioration of gearing between the gears owing to an inferior assembly precision with other parts, resulting in generation of the noise. |
