PROBLEM TO BE SOLVED: To reduce cost by making a change lever unit possible to freely set a switching action on/off point and cope with various operational angles and the switch on/off point. SOLUTION: A first shaft 21 running through a change lever 28 and rotationally moving together with the change lever 28 is supported on side walls 2a, 2b in a rotationally movable manner, a second shaft 22 running through the first shaft 21 and the change lever 28 is provided, the change lever 28 is supported in a tiltedly movable manner with respect to the first shaft 21 through the second shaft 22, a rotating sensor 41 for detecting the position of the change lever 28 and for supplying and discharging compressed air to the cylinder 37 of a pseudo-reaction mechanism 35 is mounted on the outside of the housing 1, variation of voltage value accompanying rotational movement of a sensor shaft of the rotating sensor 41 directly connected to the first shaft 21 is outputted, and the position of the change lever 28 is detected on the basis of the output. |
