本考案は．例えば複写機等に使用され樹脂製のハブを備
えた電磁連結装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is... The present invention relates to an electromagnetic coupling device that is used in, for example, a copying machine and is equipped with a resin hub.
従来、この種の電磁連結装置のうち、例えば電磁クラッ

これを同図に基づいて概略説明すると、同図において、
（１）はコイル（２）を内蔵するステータであり、（３

）により被動軸（６）に固定されている。Conventionally, among this type of electromagnetic coupling device, the one shown in FIG. 4 has been adopted as an example of an electromagnetic clutch.
To briefly explain this based on the same figure, in the same figure,
(1) is a stator containing a coil (2), and (3
) is a rotor with a fixed lining (4) and a key (5).
) is fixed to the driven shaft (6).

は常時一定のギャップ（ｇ）が保たれている。(7) is a thermoplastic resin hub having a gear (8);
It is formed into a cylindrical shape and is rotatably provided on the driven shaft (6). The hub (7) is also provided with a plurality of screw holes (9) (only one is shown) in the circumferential direction. αQ is a leaf spring for return, and screw α is screwed into the screw hole (9).
It is fixed to the hub (7) by υ. An armature (self) is fixed to a portion of the leaf spring facing the lining (4) with a rivet Q3. A constant gap (g) is always maintained between this amateur α force and the rotor (3).
したがって、コイル（２）に電流を流すと同図に破線で

れる。Therefore, when a current is passed through the coil (2), a magnetic flux (Φ) is generated as shown by the broken line in the figure, forming a magnetic circuit, and the armature α resists the elastic force of the leaf spring α0 to rotate the rotor (3).
) is attracted to. And the rotation on the drive side is a gear (8),
It is transmitted to the driven wheel (6) via the leaf spring α0, armature (self), lining (4), rotor (3), and key (5).
一方、電流を切ると磁束か消失してアマチュアＱ２は板
ばねαＱの弾撥力によりロータ（３）から離間し回転が
遮断される。On the other hand, when the current is cut off, the magnetic flux disappears, and the armature Q2 is separated from the rotor (3) by the elastic force of the leaf spring αQ, and its rotation is interrupted.
ところが、従来の電磁クラッチにおいては、ハブ（７）

あった。However, in conventional electromagnetic clutches, the hub (7)
is made of synthetic resin that expands and contracts with a large degree, so the tightening force will be lost due to loosening of the screw αυ due to thermal changes, and the leaf spring αω will be damaged, or the elastic force of the leaf spring αO will be applied to the armature Oz. It doesn't work, it disappears,
There was an inconvenience that the rotor (3) and the armature 02 came into contact even though the coil (2) was de-energized.
そこで、ねじ０υの代わりに鉄系のリベットを使用して
板ばねαωをハブ（７）にかしめ固定することも考えら
れるが、この場合かしめ圧力によりハブ（７）側の部材
が破損するという問題がある。Therefore, it is possible to use iron-based rivets instead of screws 0υ to caulk and fix the leaf spring αω to the hub (7), but in this case, there is a problem that the components on the hub (7) side will be damaged due to the caulking pressure. There is.
本発明はこのような事情に鑑みなされたもので、板ばね

Since the cylindrical portion of the leaf spring is buried in the hub and the projection of the hub is thermally deformed, the leaf spring can be reliably fixed to the hub in both the rotational and axial directions. Furthermore, due to the embedding of the cylindrical portion, the adhesion between the two members is excellent, the joint strength is high, and the fixing ability is sufficiently guaranteed. In addition, since it is not fixed with screws as in the past, screw machining is not required and assembly can be streamlined. Furthermore, since the hub is made of synthetic resin, not only is the material cost low, but there is no need to provide a bearing between the hub and the driven wheel, and costs can be reduced by reducing the number of parts.
