A shallow annular lead groove 11 is cut at a predetermined interval S by a wide lead cutter 20.
and press a slit cutter 21 narrower than the lead cutter 20 against at least every other lead groove 11 using the lead groove as a guide to form a first slit 4 reaching the shaft hole 10. In the next step, by pressing the slit cutter 21 against the remaining lead groove by shifting it half a pitch in the circumferential direction, second slits 5 perpendicular to the first slit 4 are formed facing each other with respect to the axis. It is something to do.

Due to the presence of the slits 4.4..., 5.5..., the thin wall portion 6.6... between the slits, and the connecting portion 7.7..., there is a buffering effect, and therefore, there is a buffering effect during starting and stopping. It acts to cushion the impact.

図ｂ）。 The cylindrical body 3 has a smooth circumferential surface and a hole 10 at its axis. This is rotatably supported at both ends, and then a comb-shaped lead cutter 20 is applied to the circumferential surface of the cylindrical body 3. When the cylindrical body 3 is rotated, a shallow annular lead groove 11 is cut on the circumferential surface at a distance S. Figure 4b, 5th
Figure b).
リード溝１１はリードカツタ２０の各刃の幅Ｔ
と同幅T′のものが複数列平行に切設される。 The lead groove 11 has a width T of each blade of the lead cutter 20.
Multiple rows of pieces with the same width T' are cut in parallel.
次に、円筒体３を固定してその前方より間隔が
2Sのスリツトカツタ２１をリード溝１１の上に

に正確にスリツトを形成できる。 The slit cutter 21 is of a rotary type and is moved parallel to the axis while being pressed against it.
When the slit cutter 21 is narrower than the lead cutter 20, the lead groove 11 acts as a guide, eliminating troubles such as side run-out and allowing the slit to be formed accurately at the proper position.

切設される。 Once the first slit has been cut, the slit cutter 21 is then shifted in the direction of the half-pitch axis, and
Rotate the cylindrical body 3 by 90 degrees and fix it. In this state, when the slit cutter 21 is pushed in again and moved in parallel, the first slit 4 is placed above the remaining lead groove.
A second slit 5.5 .
スリツトカツタ２１の押入深さは円筒体３の芯
軸に達する少し手前とする。 The penetration depth of the slit cutter 21 is set slightly before reaching the core axis of the cylindrical body 3.

７．７′が形成される。 When the first and second slits 4.5 are cut so as to face each other with respect to the axis, a thin wall portion 6 is formed between the slits 4.5 in the axial direction, and the slits 4.4 are cut opposite to each other with respect to the axis. A connecting portion 7.7' is formed between the slits 5.5 and the slits 5.5.
円筒体３の外周面には、第１、第２のスリツト

深さや数を少なくできる効果を生じる。 Even after cutting the first and second slits 4.5 on the outer peripheral surface of the cylindrical body 3, the lead groove 1 remains.
A portion 11' of slit 1 remains, but since this is a shallow concave groove, it has almost no effect on strength, etc., and its presence has the effect of reducing the depth and number of slits. arise.
（効果） 本発明は次のような特有の効果を有する。(effect) The present invention has the following unique effects.
スリツトは螺旋でない為圧縮、引張り、或い
は捩りに対するばね反力が均一であり、緩衝カ
ツプリングとしての性能が高い。 Since the slit is not spiral, the spring reaction force against compression, tension, or torsion is uniform, and the performance as a shock-absorbing coupling is high.

ことができる。 In order to form a wide lead groove in advance on the outer peripheral surface of the cylindrical body using a lead cutter, and to cut first and second slits on the lead groove using a narrower slit cutter, The slit does not become misaligned or distorted, processing can be performed quickly and reliably with high precision, and a shock absorbing coupling of excellent quality can be obtained.
コイルばねを巻成するような特殊な機械や設
備を要せず、任意の間隔、深さ、幅を有するス

られる。 Since the first and second slits are formed above the lead groove, a portion of the lead groove remains as a shallow concave groove, which increases the overall springiness, and the existence of this concave groove also increases the springiness. Therefore, the depth and number of slits can be reduced. Therefore, particularly small and highly accurate products can be easily obtained at low cost.
さらに凹状溝が円筒体の全周に表われる為意
匠的、審美感、乃至は機能美が高められ、外観
上体裁がよい。 Furthermore, since the concave grooves appear around the entire circumference of the cylindrical body, the design, aesthetics, and functional beauty are enhanced, and the appearance is good.
