PURPOSE:To reduce the operation force by preventing other operation elements from being operated even if an arbitrary operation element is operated, in an apparatus on which power intermission is performed from any position on a machine body by operating one of the operation elements installed at several positions on the machine body of a between-ridges working machine. CONSTITUTION:A projection element 3 is installed onto an arm 2 which is installed in projection onto a shaft crylinder 14 fitted onto a supporting shaft 13, in order to operate an intermission element 1 for connecting and disconnecting the power to a travelling apparatus from the prime mover such as tension pulley. A plurality of wires 6 which are inserted onto a fixed plate 4 fixed onto a machine body A and onto which a fitting element 5 is fitted at the top edge are allowed to penetrate through the projection element 3, and are connected to the operation elements 7 in equal number to that of the wires 6 which are installed at arbitrary position on the machine body A. A springs S is installed between th projection 3 of the wire 6 and the fixed plate 4. The arm 2 is shifted by pressing the projection element 3 by the free edge of a flexible cylinder body 8 surrounding the wire 6, through the pulling of the wire 6 connected to an arbitrary operation element 7 by operating the operating element 7, and the intermission element 1 is operated. |
