(Problems to be solved by the invention) However, in the above-mentioned conventional one, the eraser body protruding from the tip of the holder wears and disappears as it is used, and it is necessary to further project the portion fitted inside the holder from the tip of the holder. If it becomes necessary to move the part protruding from the tip of the holder in the front-back direction, for example, the pressing of the chuck part by the tightening ring is released to release the grip of the rubber part of the chuck part. It is impossible to regulate the amount of movement to the amount required by the user only by allowing the portion to move in the front-back direction. In view of this, the present invention is intended to improve the drawbacks of the above-mentioned prior art, and to allow the amount of movement of the eraser in the front-rear direction to be freely set by the user's simple operation.

(Operation) With the above configuration, when fixing the eraser body fitted inside the holder shaft, the tightening ring is engaged and pressed with the chuck portion, and the eraser body is gripped and fixed by the inward bending of the chuck portion. At the same time, when moving the eraser body in the front-back direction, the tightening ring is moved backward to release the engagement between the tightening ring and the chuck portion, and the spring-shaped section tip button portion of the tightening ring is pressed,
The spring-shaped section is bent to directly contact the guide groove engaging part with the eraser body and clamp it, and in that state, move the tightening ring by the necessary amount to move the eraser body, then release the pressing of the button part. Moreover, by moving the tightening ring forward to engage the chuck portion and press the chuck portion, the core member can be gripped and fixed again by the inward bending of the chuck portion. As described above, the eraser body can be moved by an appropriate amount by a combination of the movement of the tightening ring fitted in the holder shaft in the front-rear direction and the pressing of the spring-shaped section tip button portion of the tightening ring.

(Example) This invention is further explained by the example shown in the figures.
(1) is an eraser holder according to an embodiment of the present invention, (2) is a holder shaft whose tip portion is made of a flexible material, (3) is a chuck portion, and holder shaft (2 ) At the tip, and the vertical cross section is approximately trapezoidal,
(4) is a hollow guide groove, which is provided symmetrically in the front-rear direction at the center of the holder shaft (2), and (5) is a tightening ring, which is fitted and inserted on the outside of the holder shaft (2). 6)
Is a chuck pressing portion, which is used when the eraser (11) is gripped and fixed by the chuck portion (3).
The chuck part (3) is bent by engaging with and pressing the chuck part (3) from the outside, and (7) is an engagement stopper, which is a step projection structure inside the tightening ring (5), and is located at the rear part of the chuck part (3). By engaging with the inclined surface, the tightening ring (5) itself defines the movable amount of the holder (1) forward, (8) is a pair of spring-like pieces, and one end is an engagement stopper (7).
The other end is perpendicular to the holder (1) itself, and the button portion (9) is vertically outward and the guide groove engaging protrusion (1) is inside.
0) and is movable in the vertical direction with respect to the holder (1) itself. In the normal state, the spring-shaped section (8)
The guide groove engaging projection (10) is substantially parallel to the holder shaft (2) and does not come into contact with the eraser (11).
