下等の不都合を伴い勝ちである。Conventionally, this kind of wheel is known to have spoke plates made of steel plate or other metal plate around the outer periphery of a central drum made of steel plate or other metal plate, but originally this type of drum lacked rigidity. According to this, the vibrations of the brake shoes cannot be absorbed by the drum during braking, and tend to be amplified, resulting in inconveniences such as generation of squeal and deterioration of feeling.

させたことを特徴とする。The object of the present invention is to provide a wheel free of such inconveniences, which includes a rim 7, a drum 1 made of a steel plate or other metal plate disposed at the center of the rim 7, and a drum 1 made of a steel plate or other metal plate disposed at the center of the rim 7. In a vehicle wheel comprising a spoke plate 2 made of a steel plate or other metal plate connected to the rim 7, a flange 3 having a shaft hole 4 press-fitted to the outer periphery of the drum 1 is formed in the spoke plate 2 by bending. The bent side of the flange 3 is positioned on the open end side of the drum 1 and press-fitted into the drum 1, and the open side end of the flange 3 is bent on the bottom side of the drum 1. It is characterized by being welded onto the outer peripheral surface of the part.

The aforementioned welding or brazing of the end of the flange 3 was performed near the bent end in order to prevent distortion and sagging.

図面で７は外周のリムを示し、該リム７も鋼板その他の
金属板製とするが一般である。In the drawings, reference numeral 7 indicates an outer rim, and the rim 7 is also generally made of a steel plate or other metal plate.

果を有する。In this way, according to the present invention, the spoke plate 2 made of a metal plate has a bent flange 3 having a shaft hole 4 that is press-fitted to the outer periphery of the drum 1 made of a metal plate, and one end of the flange 3 is bent. Since the part side is positioned on the open end side of the drum 1 and press-fitted into the drum 1, the rigidity of the press-fit part is increased, brake squeal is prevented, and brake filling is improved. Since the end of the open end is welded to the outer circumferential surface of the bent part on the bottom side of the drum 1, deformation of the drum 1 due to welding of the plate 2 can be prevented, increasing welding strength, and the torch angle at the time of welding can be adjusted. It has the effect that workability is improved without any difficulty, and that the welded state can be observed from the outside, making inspection easier and quality stable.
