It becomes possible for the rotational force generated by an operating member (12, ) to be transmitted to a cylindrical movable body (13) by means of a shaft member (62) inserted slidably in the longitudinal direction in a non-rotatable fashion, inside the movable body (13), and moreover, the shaft member (62) becomes able to pass inside the movable body (13) by penetrating through the inner side of the ratchet spring section (81), a composition being adopted wherein the shaft member (62) passes through the female screw thread (11a) of the main body (11) which screws together with the male screw thread (13a) of the movable body (13). Thereby, the shaft member (62) forming a tube side rotation preventing section and the female screw thread (11a) of the main body (11) forming a tube side screw thread section overlap mutually in the same plane orthogonal to the axial direction, and furthermore, the shaft member (62) forming the tube side rotating preventing section and the ratchet teeth (14a, 14b) overlap mutually in the same plane in orthogonal to the axial direction. Consequently, the overall length can be shortened in comparison to a prior art movable body dispensing device, whilst maintaining the same dispensing amount, and hence satisfactory downsizing can be achieved.
