Abstract
To provide a work machine configured so that a filler can be used up completely.SOLUTION: A caulking gun 20 comprises: an electric motor 2 as a driving part; a housing 3 that houses the electric motor 2; a cartridge 13 which is mounted on a holder 4 provided in the housing 3 and in which a filler is housed; a pushing part 6 that is driven by the electric motor 2 to push out the filler housed in the cartridge 13; and a control substrate 8 provided with a control circuit for controlling the electric motor 2. The control circuit provided in the control substrate 8 stops output of the electric motor 2, after a piston 6b of the pushing part 6 contacts an inner wall at a filler charging-side D1 of the cartridge 13.SELECTED DRAWING: Figure 3
