とになる。Embodiment An embodiment of the present invention will be described below with reference to the drawings. First, the payout body (4) is made of plastic and has both lateral side surfaces which are flat and upper and lower both side surfaces are arcuate curved surfaces, and a male thread (1) is projectingly provided on the upper and lower side surfaces from the tip to the base end. A long screw shaft portion (2) and a handle portion (3) having a large diameter integrally provided on the base end side of the screw shaft portion (2).
And a stopper fitting groove (12) provided between the handle portion (3) and the screw shaft portion (2), and an O-ring fitting groove portion (13) provided around the front end of the handle portion (3). And 2 of the tip portion of the screw shaft portion (2),
The screw thread (1) of No. 3 is provided with a taper surface (11) whose side surface on the tip side is inclined at a required angle. The inclination angle of the taper surface (11) is set to such a value that the female thread (1) 'of the eraser receiver (9) described later can be overcome by the elastic deformation of the eraser receiver (9). ) Is relatively different depending on the elastic deformation amount. The side surfaces of the screw thread (1) other than the screw thread provided with the tapered surface (11) in the screw shaft portion (2) are actually slightly inclined, but the inclination angle of this side is, of course, that of the eraser receiver (9). The thread (1) 'is in a range that cannot be overcome. Next, the outer cylinder (6) is also made of plastic and has both ends opened, and a step portion (5) is provided on the inner surface near the opening (14) on the tip side, and the inner surface near the base end opening on the opposite side. A locking groove (15) perpendicular to the axial direction is provided in the portion. Further, the eraser receiver (9) is also made of plastic, and a cylindrical holding portion (8) which can be fixed by friction by inserting the base end portion of the eraser (7) at the tip is provided behind the long tubular portion (16).
By extending and projecting a female thread (1) 'of about one or two turns near the rear end of the tubular portion (16), that is, near the opening on the base end side. An axial split (10) that allows the inner diameter to be expanded by elastic deformation is provided on the proximal side surface. The eraser receiver (9) is provided with an eraser (7) capable of passing through the front end opening (14) of the outer cylinder (6) in its front end holding portion (8) so as to be slidable in the outer cylinder (6) in the axial direction. It is housed. However, as shown in FIG. 3, a flat surface portion (17) is formed on the side surface portion of the eraser receiver (9), and a flat surface portion (17) 'is also formed on the inner surface portion of the outer cylinder (6) which faces the flat surface portion (17). Therefore, the eraser receiver (9) cannot rotate with respect to the outer cylinder (6). The stopper fitting groove (12) and O in the above-mentioned delivery body (4)
A stopper (18) and an O-ring (19) are fitted in the ring fitting groove (13), respectively, and the screw shaft portion (2) and the stopper (18) of the feeding body (4) are placed inside the outer cylinder (6). As shown in FIG. 4, the ribs (20) protruding from the side surface of the stopper (18) are inserted into the locking grooves (15) on the inner surface of the outer cylinder (6) and fixed, and the feeding body ( 4) is attached to the outer cylinder (6) rotatably but immovably in the axial direction. still,
It is also possible to lock the delivery body (4) directly and rotatably with respect to the outer cylinder (6). The screw shaft (2) of the payout body (4) is inserted into the tubular portion (16) of the eraser receiver (9) so that the screw (1) of the screw shaft (2) and the screw of the eraser receiver (9). (1) 'is screwed. As shown in FIG. 2, when the handle portion (3) of the feeding body (4) is rotated with the eraser (7) completely retracted into the outer cylinder (6), the eraser receiver (9) causes the screw shaft (9) to rotate. The eraser (7) is sent forward by the part (2) and the tip end opening (1
The eraser (7) can be used by protruding from 4). If the handle portion (3) is rotated in the opposite direction, the eraser (7) will be retracted into the outer cylinder. Then, as shown in FIG. 1, when the eraser (7) is fed to the vicinity of the base end and the tip of the eraser receiver (9) is in contact with the stepped portion (5) in the outer cylinder, the eraser receiver (9) is removed. ) Screw thread (1) 'engages with the thread thread (1) having the tapered surface (11) at the tip of the screw shaft section (2), and the handle section (3) is further rotated. Even if it is done, the eraser receiver (9) cannot move forward, and conversely, the eraser receiver (9) expands its inner diameter by elastic deformation and changes its screw thread (1) 'into the screw thread (1) of the screw shaft (2). Since the screw thread (1) 'of the eraser receiver (9) gets over the taper surface (11) of the scraper shaft portion (2) and finally gets over the screw thread (1) having the taper surface (11) of the screw shaft portion (2). The screw shaft (2) will idle.
