HINGE MECHANISM

To enhance durability and reliability of a hinge mechanism having a drive source.SOLUTION: A hinge mechanism 20 connects a first housing and a second housing so as to be relatively rotatable. The hinge mechanism 20 includes: an electric motor 30 provided in the first housing; a coupling shaft 40 rotationally driven by the electric motor 30; and a torque transmitting member 50 that rotates integrally with the second housing and frictionally engages with the coupling shaft 40. When torque exceeding transmission torque capacity acts on the torque transmitting member 50, a slip occurs between the coupling shaft 40 and the torque transmitting member 50.SELECTED DRAWING: Figure 5 【課題】駆動源を備えるヒンジ機構の耐久性や信頼性を向上させる。【解決手段】ヒンジ機構２０は、第１筐体と第２筐体とを相対回転可能に連結する。ヒンジ機構２０は、前記第１筐体に設けられる電動モータ３０と、電動モータ３０によって回転駆動される連結シャフト４０と、前記第２筐体と一体的に回転するとともに、連結シャフト４０と摩擦係合するトルク伝達部材５０と、を有する。そして、伝達トルク容量を上回るトルクがトルク伝達部材５０に作用すると、連結シャフト４０とトルク伝達部材５０との間に滑りが生じる。【選択図】図５
