PURPOSE:To freely move selectively a supporting tool to a necessary position of a chassis and connect the tool to the chassis and move the supporting tool freely without taking the tool out of the chassis by forming a long hole in the chassis and forming a screw hole in the supporting tool. CONSTITUTION:A long hole (supporting hole) 27 to be formed in a chassis 21 is made to be the same length as the distance between joining positions of each supporting tool 26 along the axial direction of the chassis 21 or to be optional necessary length based on the purpose. Each tool 26 is connected with and supported by the chassis 21 by inserting a screw 30 in the hole 27 and screwing the screw in a screw hole 28 to fasten the screw. Consequently, by loosening the screw 30 and moving the screw in the inside of the hole while being inserted in the hole 27 and the screw hole 28, the tool 26 is moved along the hole 27. That is, by moving the screw 30 along the hole 27, the tool 26 is freely moved selectively to the necessary position of the chassis 21 to be placed in its connection and at the same time without being taken out of the chassis 21, the tool 26 is moved by easy operation, so that the workability at the time of moving the tool 26 can be improved. |
