PROBLEM TO BE SOLVED: To improve handleability and workability of a caulking gun by removing projection from a body part of an electric motor because in the conventional electric caulking gun, an electric motor is arranged in a state of being projected to the side of a body part and thus handleability and workability are poor.SOLUTION: A speed reducing gear train 23 to 25 is arranged on an axial line J parallel with an output shaft 10a of an electric motor 10 internally installed in a body part 2 and the electric motor 10 is internally installed almost uniformly on the right and left sides of an extruding rod 6 to be advanced and retreated across the center of the body part 2 in a width direction, so that projection to one side in a conventional caulking gun can be removed. |
