Abstract: A grease gun (1; 1A-1I) includes: a brushless motor (20); a pump (60) configured to be driven or drivable by the motor; a motor-housing part (4), which houses the brushless motor; a pump housing (45), which contains the pump and extends in an up-down direction; a tank (54), which supplies grease to the pump; and a front-tube part (67) provided at a front portion of the pump housing. A front end of the tank is connected to the pump and extends in a front-rear direction that is perpendicular to the up-down direction.
