度を検知しうるものである。 In the present invention, as described above, the chain bands connected to both the left and right sides of the end of one of the towing machine side frame and the work machine side frame are rotatable with respect to the same frame. The guide wheels are arranged on both the left and right sides of the end of the other pivotally supported frame, and the chain ring is fixed to a vertical rotation shaft provided on the towing machine side frame. Therefore, as the work machine side frame rotates, the chain band moves along the outer periphery of each guide ring and chain ring, and the chain ring that engages with the chain band moves along the vertical rotation axis of the work machine side frame. Rotates in proportion to the rotation angle. Since a potentiometer is disposed at the end of the vertical rotation shaft, the rotation angle of the vertical rotation shaft is detected by the potentiometer,
By inputting this detection signal into a computer and performing numerical calculations, the rotation angle of the work machine side frame can be detected.

になつている。 The vertical rotating shaft 5 is comprised of a bearing tube 8 fixed to a lower vertical piece of a groove-shaped support frame 7 and an upper horizontal piece 7.
A bifurcated arm piece 10, which is rotatably supported by a bearing 9 hanging vertically from a, and which protrudes from the side of the support frame 7, is rotated by a mounting frame 11 fixed to the towing side frame A. A bullet 13 is interposed between the vertical part 11a of the mounting frame 11 and the tip of the arm piece 10, and the support frame 7 is moved by the urging force of the bullet 13. In turn, the chain sprocket 6 moves to the opposite side of the towing side frame A from the working machine side frame, so that the chain 2 is always kept under tension.
