When doing so, as shown in Fig. 4, both the pointed ends b',
b' and both outer sides of the base of the protrusion d of the knob c are tightly slid together, which not only makes the insertion operation troublesome, but also causes wear, especially on both apical ends b' of the split groove and both outer sides of the protrusion. There were some drawbacks such as the generation of dust.

In a knob made of hard synthetic resin that fits tightly into the shaft piece, two protrusions are provided parallel to each other with an interval along the axial direction on the inner peripheral surface of the shaft fitting hole of the cylindrical knob body. The thickness of the protrusions and the total width of their intervals are equal to or slightly larger than the width of the grooves on the shaft piece, and grooves are formed on the inside of the knob body along the outside of the base of both protrusions. It is characterized by

る。(Function) When the knob of the present invention is fitted onto the shaft piece a, as shown in FIG. fit inside,
At this time, the total width α of the thickness of the two protrusions 3, 3 and the interval 4 between the protrusions was formed to be equal to or slightly larger than the width of the split groove b, so that both protrusions 3, 3 and the split groove b were formed. In addition, since the shaft fitting hole 2 of the knob is generally made to have a slightly smaller diameter than the shaft diameter at the time of manufacturing, in that fitted state, the shaft piece will fit tightly as shown by the arrow in Figure 3. Both sides of the split groove b at a are pressed inward, thereby compressing the width of the split groove b and pressing the outside of both the protrusions 3, 3. The tight fitting between the shaft piece a and the knob body 1 becomes strong, and the integral connection between the shaft piece a and the knob body 1 becomes reliable, and the connection does not loosen due to vibrations, etc. without causing core runout or surface runout, and furthermore, the shaft piece a and the knob body 1 are tightly connected. In the insertion operation, both pointed ends of the split groove b of the shaft piece a
Since b' and b' face the concave grooves 5 and 5 provided along both outer sides of the bases of the protrusions 3 and 3, the pointed ends b' and b' are not affected by contact, and the insertion and binding operation is easy. It becomes smooth.

た。 In the drawings, 1 indicates a knob body, 2 indicates a shaft fitting hole, and two protrusions 3, 3 are provided in the axial direction along the inner surface of the fitting hole 2 with a spacing 4 therebetween. And the total width α of the thickness of the two protrusions 3 and 3 and the interval 4
is formed to be equal to or slightly larger than the width of the groove b of the shaft piece a, and grooves 5, 5 are formed inside the knob body 1 along both outer sides of the bases of both protrusions 3, 3, respectively.

得る効果を有する。(Effect of the invention) According to the invention, two protrusions are provided at an interval along the axial direction on the inner circumferential surface of the shaft fitting hole of the knob body, and the width of the protrusions is set by the dividing groove of the shaft piece. Because the width is equal to or slightly larger than the width of the protrusion, the reaction force against the tendency of both protrusions to be pushed toward the protrusion gap when the protrusion and the split groove of the shaft piece are engaged, and the close fit of the knob body to the shaft piece. At times, the shaft piece contracts in the split groove, and the action of pinching both protrusions with both sides of the split groove makes the connection between the shaft piece and the knob strong, and prevents problems such as center runout and surface runout due to loosening due to use. In addition, since grooves are formed on the outside of each base of both protrusions, when mating with the grooved shaft piece, the pointed ends of the grooves on both sides can be fitted without coming into contact with the inner surface of the knob. This has the effect of making it easier and smoother to insert the two, and preventing problems caused by wear of the contact portion between the knob and the shaft piece.
