  In FIG. 1, by driving the motor 7, the rotation is transmitted to the eccentric rotor 5, and the rotation of the eccentric rotor 5 causes the ring-shaped pressing member 4 to perform an eccentric motion. Due to this eccentric movement, the compressed portion of the chemical solution transport tube 3 moves in one direction, and the fluid in the chemical solution transport tube 3 is sent out.

  The chemical solution transport tube 3 is made of a flexible material selected according to the fluid to be delivered, for example, rubber or synthetic resin, and is arranged in a ring shape along the inner peripheral surface of the cylindrical chamber.
