Abstract:
1. A sander comprising: a housing; an upper portion of the housing configured as a holding portion; an output shaft that rotates around a rotational axis, the rotational axis of the output shaft extending in a vertical direction inside the housing and being configured to be aligned with the upper portion; a pad configured to be driven about the output shaft; a battery removably attached to an outside of the housing, the battery is removably attached to an attachment portion of the housing; and a motor powered by the battery and configured to drive the pad, the motor being disposed inside the housing, wherein the battery is elongated along a longitudinal axis such that when the battery is attached to the housing, the longitudinal axis is oriented at an angle not less than 0 degrees with respect to the vertical direction, the motor is disposed on a side opposite to the attachment portion with respect to a position of the holding portion, the rotational axis of the output shaft is provided perpendicular to the pad and parallel to a rotation shaft of the motor, and the battery is arranged such that the longitudinal axis is oriented at an angle not less than 0 degrees with respect to the rotation shaft of the motor, and the battery is slidably attached to the attachment portion from a direction parallel to the longitudinal axis, and a height of the housing in the vertical direction along the rotational axis of the output shaft is longer than a longest length of the housing in a horizontal direction, from a front of the housing to a back of the housing.
