PURPOSE:To surely stop a lever in the advance and retreat position while increase a response of the lever so as to perform sure operation by using a magnetic member for a stopper to control a turn of a shaft of a direction switch. CONSTITUTION:When a position of a lever 3 is moved from a neutral to an advance, a cam 6 turns together with a shaft 5 while rolling a roller 7 located in a neutral position of a recessed part 6b on a wave face part 6a to get in the advance position. Then, the cam 6 powerfully hits a stopper 131 so as to return by reaction but to be attracted by magnetic force of the stopper 131 for staying in the advance position. When the lever 3 is returned from the advance position to the neutral position, an operator feels the response of the level 3 heavier in order to call attention to the operator, and this promotes sure operation of firmly grasping the level 3. |
