A pair of side-face grooves, into which the user can place the thumb and forefinger, are formed in both side faces of the housing. A depth changing portion is formed in at least one of the side-face grooves, such that the depth is reduced toward the back-end face of the housing. According to this structure, even when the housing is gripped directly from the back-end face, the user can easily draw up or raise the power tool. | 2012-11-22 |
