PROBLEM TO BE SOLVED: To provide a fluid ejector reducing abrasion and improving durability. SOLUTION: A tube 2 where fluid flows in its inside is arranged along the storage wall 34 of the inner wall of the storage section 3A of a case 3. An internal teeth 41 is arranged around the inner periphery of a ring 4 and engaged with an idle gear 6, and the idle gear 6 is engaged with a sun gear 5. When the sun gear 5 is rotated by a motor, the idle gear 6 is revolved while rotating and push-presses the ring 4. The ring 4 eccentrically rotates (rolls) along the storage wall 34, and sequentially transfers and ejects fluid in the tube 2. Rotational movement is transmitted to the ring 4 by the engagement of the gears, therefore, abrasion on the inner periphery of the ring 4 can be reduced, and the durability of a tube pump 1 can be improved.
