<p>PURPOSE:To make it possible to largely change the position of a rear-view mirror by providing a detent structure member, a detent fitting member and a detent urging spring between a rear-view support rod and a pivotal support cylinder so that the support rod are rotatably fitted in or fixed by detent to the pivotal support cylinder. CONSTITUTION:A flying rod 11 for a pivotal support shaft 7 is secured to a front support column 10 of a tractor above a boarding grip 13. In this arrangement a support rod 13 for a rear-view mirror 1 and a working lamp 2 is pivotally fitted in the pivotal support cylinder 7. Further, a detent fitting member 8 is urged downward by a detent urging spring 4 in the part of the support rod 13 which pierces through the pivotal support shaft 7 and projects downward, and the periphery of the detent urging spring 4 is protected by a spring protection cylinder 5. Further, a cylindrical detent structure member 9 is fixed to the inner periphery of the pivotal support cylinder 7, and the support shaft 3 is made to pierce through the detent structure member 9. With this arrangement, when the support rod 3 is rotated around the pivotal support cylinder 7, the positions of the rear-view mirror 1 and the like may be changed.</p> |
