て連結するようにしたものがある。In recent years, as automobile wheels have become more sophisticated and the desire for high design has been achieved, there has been an increase in the use of full-face type wheels, as shown in FIG. 1, in which the outer flange portion of the rim 2 is formed from a portion of a disk. Conventionally, such a wheel is manufactured by forming a deformed rim 2a having a flange on one side in advance by spinning as shown in FIG. 9, and then welding it to the disc 1 as shown in FIG. There is one that is connected by 3.

、ひいては安全性にも影響する問題がある。However, in the above manufacturing method, the rim 2
When welding a, the welding heat is transmitted to the rim 2a, causing thermal distortion in the rim 2a, and the set shape of the rim may be deformed, resulting in large rotational runout of the wheel. This causes vibrations when the vehicle is running, leading to a worsening of ride comfort and, ultimately, the problem of affecting safety.

を特徴とするものである。In order to solve the above-mentioned problems, the present invention provides a full-face type wheel in which the outer flange of the rim is formed by a part of the disk, in which a cylindrical hoop material (2b) is welded and fixed to the inside of the disk (1). After that, the hoop material (2
b) is characterized in that it is formed into a rim shape by spinning.
〔実施例］
次に本発明の実施例を第１図乃至第８図に基づいて説明

。In order to manufacture the wheel shown in FIG. 1, the disc 1 shown in FIG. 2, which is manufactured in advance for a full-face type by forging or casting, and the hoop shown in FIG. 3 for forming the rim are required. Prepare material 2b. This hoop material 2b is made by rolling a flat plate of aluminum or the like into a cylindrical shape and welding the butt ends, or by cutting an extruded material into a predetermined width. The diameter is set to fit the outer peripheral surface of the rim attachment piece 1a. Note that the disc mounting side 2 of the hoop material 2b
c may not be a perfect circle as shown in Figure 4 (A), so it can be made as shown in Figure 4 (B) by preliminary processing by spinning.
As shown in the figure, it is best to make the inner diameter close to a perfect circle and increase the accuracy of the inner diameter.
次に、前記フープ材２ｂにおけるディスク取付側２ｃを

The rim is then spun to form a predetermined rim shape.
この成形により、第１図に示すようなホイールが形成
