PROBLEM TO BE SOLVED: To enable a large amount of a content liquid to smoothly discharge with a little force, to avoid increasing remarkably a device scale and to keep high operability. SOLUTION: This pump dispenser is constituted so that a moving cylinder 38 is moved in an outer cylinder 32 by operating a trigger 54 to discharge fluid sucked from the end part of the outer cylinder. In this case, a gear 56 rotated by actuating force to the trigger 54 and a rack 68 formed in the moving cylinder are provided and the moving cylinder 38 moves straight by transmitting the rotational force of the gear 56 to the rack 68. |
