PROBLEM TO BE SOLVED: To solve the problem in a conventional swash plate operating mechanism that a tolerance of a distance between a pin member fixed to an operation lever and a guide pin fixed to a housing, and a neutral position of an operation lever must be strictly set. SOLUTION: The operation lever 21 of a trunnion shaft 9 comprises the pin member 23 and the guide pin 38, which are arranged in two different points on the same radial line in the trunnion shaft 9. A first cam hole 22a and second cam hole 25 corresponding to the pin member 23 and guide pin 38 are formed on the cam plate 22m of an operation rod 22, respectively. The second cam hole 25 is formed of an elliptic hole part 25a parallel to the first cam hole 22a, a one-side operation part 26b connected to one end of the elliptic hole part 25a and formed in a circular shape having one end part of the first cam hole 22a as the center, and the other-side operation part 25c connected to the other end of the elliptic hole part 25a and formed in a circular shape having the other end part of the first cam hole 22a as the center.
