ずかしくなる。2. Description of the Related Art A side knock type sharp pencil is provided with a chuck mounting body (chuck top) having a chuck for gripping a core in a shaft cylinder, and an inclined surface is formed at a rear end of the chuck mounting body. The knocking member provided on the side surface of the shaft cylinder presses the inclined surface to advance in the axial direction.
As this knock member, a knock lever provided so as to be swingable in the axial radial direction with the rear end as a fulcrum and a knock button movable vertically along the axial radial direction of the shaft cylinder are generally used. Also in the case of, the chuck is attached to the chuck attachment body that is pressed in the axial direction by the knock member, so that when the attachment body is pressed, the chuck is also pressed in the axial direction at the same time and the axis of the chuck moves. There was a fear. When the knock operation is performed on the core held by the chuck,
Since the elastic core holder (breaker portion) provided in the die projects through the core insertion hole and projects from the tip of the die, the chuck core and the elastic core holder are as described above. If the axis of the core shifts, it becomes difficult to smoothly project the core.

した如き繰出不良の原因となることがあった。Moreover, since the chuck mounting body slides in the axial direction while being pressed against the inner surface of the shaft cylinder, the sliding surface is easily worn. Therefore, the position of the axis of the chuck mounting body may deviate from the initial fixed position depending on the amount of wear. Due to such a cause, the chuck mounting body and the elastic core holder (breaker portion) may be displaced. There is a case where the center of the sheet shifts and causes the feeding failure as described above.

なるからである。In Japanese Utility Model Publication No. 55-23900 and Japanese Utility Model Publication No. 60-78490, an engaging element having an inclined surface is formed as a separate body and is inserted into a center shaft or a core guide tube to attach a chuck. Side knock type chassis that is connected to
Puppencil is described. However, since these engaging elements can move freely in the axial length direction, it is necessary to work while holding the engaging elements in the front position with the mouthpiece direction of the shaft tube facing downward when assembling the knock member. Therefore, workability is not good, and it may be troublesome and useless. This is because if the above-mentioned engagement element is displaced toward the rear end of the axial length, it cannot be combined with the knock member.

簡単で無駄なコストが発生するおそれもない。The present invention is constructed as described above, and the chuck for holding the core is attached to the chuck mounting body, and the mounting body is pressed by the knock member provided on the side surface of the shaft cylinder so as to be capable of being pressed in the axial radial direction. In a side knock type sharp pencil in which a core is extended from a shaft cylinder, an inclined surface member having an inclined surface with which the knock member engages is provided on an outer surface, and a shaft is provided on either one of the chuck mounting body and the inclined surface member. A receiving groove that extends in the radial direction is formed, and an engaging projection that engages with the receiving groove is formed on the other side, and when the slope member is pressed by the knock member, the receiving member is moved in the pressing direction in the receiving groove. Since the slanting member is attached to the chuck mounting body by loosely fitting the engaging projection, when the knocking member is pressed, the slanting member is only sandwiched between the knocking member and the inner surface of the shaft cylinder, and the chuck mounting body has a shaft. Radial direction It is possible to prevent the pressing force from acting.Therefore, the centers of the core insertion holes of the chuck and the die are displaced so that the core is difficult to come out, or the chuck mounting body is greatly worn away from the fixed position to one side and It is possible to use it lightly without causing a failure such that the center of the core insertion hole is displaced. In addition, since the slope member does not move in the axial direction with the slope member attached to the chuck mounting body during assembly, the assembly work is simple and there is no risk of wasted cost.

However, since the present invention has a structure in which the slope member is separately formed and attached as described above, only the slope member needs to be made of such a special plastic material and can be economically manufactured. .
