PROBLEM TO BE SOLVED: To provide a constitution capable of inexpensively and surely sandwiching a spring plate of a plate spring part for elastically supporting a piston rod, in a vibrational compressor for compressing fluid by reciprocating motion of a piston. SOLUTION: A flexure spring 25 (the plate spring part) is formed into a laminated structure composed of a flexure 2 (the spring plate) and a spacer 27. A spacer hub 27a and a spacer rim 27b of the spacer 27 are formed so as to respectively correspond to a hub part 26c and a rim part 26d of the flexure 26. A projecting polygonal hole part 27f is arranged in the spacer rim 27b. The root 26f on the rim part 26d side of an arm part 26e for constituting the flexure 26, is pressed down in the substantially orthogonal direction to the extending direction of the arm part 26e by the peripheral edge 27g of the hole part 27f, in a state of being superposed on the flexure 26.
