て絞り込んだテーパ面を介して連結されている。At the upper end of the bearing 6 inside the opening 8, a cylindrical locking portion 13 fitted into the annular groove 3 is provided coaxially. The inner wall surface of the locking portion 13 and the inner wall surface of the bearing portion 6 are connected via a tapered surface whose inner diameter is narrowed upward.

箇所の位置に設けている。Here, the feature of the reel receiver according to the present invention is that a plurality of V-shaped grooves 14 are provided on the peripheral surface of the locking portion 13 in parallel with the axial direction thereof. In this embodiment, the V-shaped grooves 14 are formed at equal intervals in the circumferential direction of the locking portion 13.
It is provided at the location of the location.

しを規制することになる。As shown in FIG. 3 (a), when the reel receiving body 5 is fitted into the reel supporting shaft 2 from above and integrated therewith, as shown in FIG. Receives a force that contacts the inner wall tapered surface of the locking portion 13 and pushes the locking portion 13 outward, breaking the thin portion at the bottom of the groove and moving the locking portion 13 outward. This facilitates elastic deformation. When the locking portion 13 gets over the head of the reel support shaft 2 due to this elastic deformation, FIG.
As shown in (b), the elastic return action fits into the annular groove 3 to restrict the reel receiving body 5 from coming off from the reel support shaft 2.

トを設けるようにすると、その成形加工時に円筒内径面
に素材がはみ出す、所謂バリが生じやすくなる。In place of the V-shaped groove 14, an elongated slit may be formed on the peripheral wall of the locking portion 13 in advance. However, since the locking portion 13 itself has a very small diameter, it is generally very difficult to integrally mold the reel receiving body 5 with synthetic resin with high accuracy. For example, if a slit is provided in the locking portion 13, the material protrudes from the inner diameter surface of the cylinder at the time of molding, so-called burrs are likely to occur.

とが可能となる。In this regard, in order to provide the V-shaped groove 14 on the peripheral surface of the locking portion 13, it is only necessary to form a projection corresponding to the V-shaped groove by, for example, electric discharge machining in the mold. Part 1
Since the inner diameter surfaces of the cylinders 3 are connected seamlessly, the above-described problem of the occurrence of burrs is eliminated. As a result, the reel receiving body 5 having the above-described shape can be integrally formed with high precision.
【0019】かくして上述した如く構成されるリール受

することができる。しかも円筒状の係止部13を環状溝
3の全周に亘って嵌合させることができるので、その抜
け止め強度を十分に高くすることができる。Thus, according to the reel receiver configured as described above, the reel itself can be formed easily and with high precision. Moreover, since the cylindrical locking portion 13 can be fitted over the entire circumference of the annular groove 3, the retaining strength thereof can be sufficiently increased.
【0020】また従来のようにリール支持軸に係止部を
設ける構造ではないので、リール支持軸2の径を小さく
し、これを回転自在に支持する軸受部6の内径も小径に
することができるので、そこでの回転接触抵抗を小さく
することができる。Since the reel supporting shaft is not provided with a locking portion as in the prior art, the diameter of the reel supporting shaft 2 is reduced, and the inner diameter of the bearing portion 6 for rotatably supporting the reel supporting shaft 2 is also reduced. As a result, the rotational contact resistance there can be reduced.
【0021】尚、本考案は上述した実施例に限定される

である。The present invention is not limited to the above embodiment. Although two V-shaped grooves 13 are provided in the embodiment,
It is also possible to provide three or more locking members 13 as long as the strength is not impaired. Further, here, a connecting portion 15 is provided between the locking portion 13 and the bearing portion 6 for facilitating the bending of the locking portion 13. What is necessary is just to determine according to specifications, such as. Further, the fitting shape between the annular groove 3 and the locking portion 13 can be variously modified.

できるので回転抵抗が少ないものとなる。According to the reel receiver having the above-mentioned structure, since the locking portion is cylindrical and has no slit as in the prior art, no burrs are generated at the time of forming, so that the formability is good. In addition, the entire circumference of the cylindrical inner diameter of the locking portion enters the annular groove, so that sufficient retaining strength can be obtained. Furthermore, the bearing can be mounted simply by pushing the bearing portion of the reel holder into the reel support shaft, and the diameter of the bearing hole fitted with the reel support shaft can be reduced, so that the rotation resistance is reduced.
