Patent ID: RE41300

Claim:
A movable body dispensing device comprising: a cylindrical movable body having a male screw thread formed on the external circumference thereof; a cylindrical main body having a female screw thread which screws together with the male screw thread of said movable body, formed on the intermediate portion of the internal circumference thereof; a cylindrical operating member coupled rotatably to the rear end section of said main body, comprising a shaft member provided so as to project towards the front side from a base provided at the rear end thereof, said shaft member being fittable slidably in the longitudinal direction, in a non-rotatable fashion, into said movable body engaged with said female screw thread; and a ratchet comprising a set of ratchet teeth and a ratchet spring, for restricting the movement of said movable body in the forward direction or rearward direction; said movable body being progressively dispensed by causing relative rotation of said main body and said operating member; wherein a step section is formed on the inner part of said cylindrical main body between the internal circumference of said intermediate portion and the internal circumference of the region apart from said intermediate portion; said ratchet comprises a cylindrical ratchet spring section whereon at least one of said set of ratchet teeth and said ratchet spring are formed integrally; and said ratchet spring section is sandwiched between the step section of said main body and the inner side of said operating member, in such a manner that said shaft member penetrates through the inner side of said ratchet spring section and thereby enables said movable body to pass through the same.
