PURPOSE:To permit the sure set at a neutral position by fixing a rotary member which integrally revolves onto a control shaft and installing a node mechanism which is engaged at a neutral revolution position between the rotary member and a stop member. CONSTITUTION:A node mechanism 94 is installed between a revolving lever (rotary member) 48 directly fixed onto a control shaft 60 and a bracket (static member) 91 fixed onto a transmission body in correspondence with a neutral position on a hydraulic transmission 20. The mechanism 94 is constituted of a ball 92 held by a ball holder 95 and a triangular cut part 93 formed on the edge surface of the lever 48. Since the ball 92 is energized towards the edge surface of the lever 48 at all times by a spring which is installed in the holder 95 and not shown in the figure, the ball 92 is automatically fitted into a cut part 93 by the energizing power of the spring, when the lever 48 is turned to the position close to the neutral position, and the lever 48 is surely fixed at the neutral position. |
