摘要： In a pendulum arrangement of a pendulum clock having a pendulum arm hanging a pendulum disc on one end and being pivotally and swingingly supported at a supporting portion of a base plate, an electromagnet fixed to the base plate and a permanent magnet arranged facingly to the electromagnet and swinging together with the pendulum arm for the purpose of swinging a pendulum by means of electromagnet force of the electromagnet and the permanent magnet, a pendulum arrangement further comprising a slip arm one end of which the permanent magnet is fixed and on the other end of which is loosely engaged with the pendulum arm at a little larger slipping torque than a driving torque which said permanent magnet receives from the electromagnet, and a pair of limit pins fixed on the both side of the swinging region of the slip arm on the base plate, wherein either one of the limit pins touches the slip arm to slip the slip arm away from the pendulum arm and the permanent magnet always swings so that it can center the electromagnet.
