ブを提供することを目的とする。 This invention was made in view of the above circumstances,
A hub body 11 having a boss portion 11b extending along the axis via a radial rib portion 11a, and a connecting portion 12b disposed on the outer peripheral side of the boss portion 11b of the hub body 11 and facing toward the rib portion 11a. and a sprocket holder part 12 having a reinforcing part 12a protruding toward the boss part 11b, the hub body 11 and the sprocket holder part 12 are each formed by forging separately, The boss part 11
b, and the connecting portion 12b is welded to the rib portion 11a to connect the hub body 11 and sprocket holder portion 12.
For two-wheeled vehicles, the strength can be improved and the weight can be reduced by integrally molding the reinforcing part 12a, the boss part 11b, the connecting part 12b and the rib part 11a to form the hollow part A. The purpose is to provide a hub.
以下、図示の実施例を参照しながら本考案を詳
細に説明する。 Hereinafter, the present invention will be described in detail with reference to illustrated embodiments.
第２図において、ハブ１０はハブ本体１１とス
プロケツトホルダー部１２とで構成されており、
これらハブ本体１１とスプロケツトホルダー部１
２とは鍛造により各別に成形し、溶接１３により
一体に成形されている。 In FIG. 2, the hub 10 is composed of a hub body 11 and a sprocket holder part 12.
These hub body 11 and sprocket holder part 1
2 and 2 are formed separately by forging and integrally formed by welding 13.
ハブ本体１１は内側に向けて延出した半径方向
のリブ部１１ａを介して軸線上にボス部１１ｂを
延出したもので、このボス部１１ｂの外側にスプ
ロケツトホルダー部１２が熔着されている。スプ
ロケツトホルダー部１２はリブ部１１ａに向けて
筒状の接続部１２ｂを突設し、かつ内周面側に向
けて補強部１２ａを突設してある。 The hub body 11 has a boss portion 11b extending along the axis through a radial rib portion 11a extending inward, and a sprocket holder portion 12 is welded to the outside of the boss portion 11b. There is. The sprocket holder portion 12 has a cylindrical connecting portion 12b protruding toward the rib portion 11a, and a reinforcing portion 12a protruding toward the inner peripheral surface side.
