ているのが現状である。 When molding the reel casing of a fishing reel from aluminum die-casting, synthetic resin, etc., the fitting hole of the bearing that supports the handle shaft and the bearing that supports the rotor rotating shaft cylinder should be directly aligned with the bearing outer diameter using the mold. If molded in such a way, it may be difficult to remove the mold due to so-called galling, or the accuracy may be compromised. Currently, the bearing is reamed to match the outer diameter of the bearing.
しかしながらこの方法によるときは金型成型加

きない欠陥がある。 However, when using this method, molding and reaming are required, and it is troublesome to ensure dimensional accuracy such as centering, and there are also defects that prevent the use of the highly hard chilled layer, which is a feature of die-casting. be.
本発明はこれらの欠陥を改善するようにしたも
ので、リール筐体を型成型するに当り金型でベア
リング外径より大径のテーパー孔とその内周面に
適宜間隔で設けられたベアリング支承突部とを一
体に成型することを要旨とするものである。 The present invention has been made to improve these defects, and when molding the reel housing, a tapered hole with a diameter larger than the outer diameter of the bearing and bearing supports provided at appropriate intervals on the inner circumferential surface of the mold are used. The gist of this is that the protrusion and the protrusion are integrally molded.
本発明方法はリール筐体に金型でベアリング嵌

所謂カジリの発生を防止し、従来のようなリーマ
加工を必要とせず金型成型加工だけでベアリング
嵌着孔を形成でき、リールの製造工程を著しく簡
易化できる。 In the method of the present invention, when forming the bearing fitting hole in the reel casing with a mold, it is integrally formed with a tapered hole having a diameter larger than the outer diameter of the bearing and bearing support protrusions at appropriate intervals on the inner peripheral surface of the hole. The slope between the bearing bearing protrusions of the tapered hole acts as a relief part to prevent so-called galling, and the bearing fitting hole can be formed only by molding without the need for conventional reaming. The manufacturing process can be significantly simplified.
また本発明は金型成型加工だけであるためベア
リングが支承するハンドル軸、ローター回転軸筒
等に対する芯ずれを生ずることもなく寸法精度の
確保も容易であると共に金型成型加工の特徴であ

耐久性も向上することができる。 In addition, since the present invention involves only molding, there is no misalignment with respect to the handle shaft supported by the bearing, the rotor rotating shaft cylinder, etc., and it is easy to ensure dimensional accuracy. Durability can also be improved because the large chill layer can be used as is.

る。 An embodiment of the present invention will be described with reference to the drawings. A bearing 3 that supports a rotor rotating shaft cylinder 2 of a reel housing 1 made of aluminum die-casting, synthetic resin, etc.
When molding the fitting holes 4 and the fitting holes 4, 4 of the bearing 3 that supports the handle shaft 5 with the mold 6,
The bearing 3 is integrally molded with a mold 6 so that bearing support protrusions 8 are formed at appropriate intervals on the inner peripheral surface of a tapered hole 7 having a diameter larger than the outer diameter of the bearing 3, and the bearing 3 is fitted between the bearing support protrusions 8. I support it.

る。 FIG. 4 shows an example of molding the fitting hole 4 of the main body 9 of the reel housing 1. The mold 6 consists of a fixed mold 10, a movable mold 11, and a core 12. By injecting hot water such as synthetic resin through the gate 14, the fitting hole 4 is integrally molded with the main body 9, its front part and side parts at the same time.

ものである。 Therefore, in the present invention, the slope of the tapered hole 7 facilitates the removal of the mold 6 and prevents the occurrence of so-called galling, and the bearing 3 can be fitted as is between the bearing bearing protrusions 8, making the manufacturing process extremely easy. Moreover, there is no need for alignment of the rotor rotating shaft cylinder 2 and the handle shaft 5, and a chill layer can also be used, which has an excellent feature of improving durability.
