PURPOSE:To provide an operation mechanism by which forward/backward movement gear shift operation can be performed with automobile feeling. CONSTITUTION:A driving arm 3 for a hydrostatic continuously variable transmission capable of forward/backward movement gear shift operation is formed in such a manner that operation in the forward direction from a neutral position accelerates forward movement while operation in the backward direction from the neutral position accelerates backward movement. An acceleration pedal which can be operated by depression in the forward direction is connected to the driving arm 3 via a balance arm 6, and a switching lever 9 is interlocked with the balance arm 6 via a connecting rod 12, junction arm 11 and switching arm 10 so that either direction of forward or backward movement can be selected by operation of the switching lever 9. |
