Abstract: A record player includes a turntable, a drive motor, a non-contact transmission mechanism, a tone arm, and a housing. The non-contact transmission mechanism includes a drive-side rotor and a magnetic member. The drive-side rotor is rotated by a driving force of the drive motor. The drive-side rotor is formed of a permanent magnet. The magnetic member is constituted of a soft magnetic body. The turntable is rotated according to the rotation of the drive-side rotor by an attraction force acting on the magnetic member from the permanent magnet.

Abstract: A Bourdon tube pressure gauge includes: a Bourdon tube; a rotary piece rotatably attached to a first shaft arranged near a tip of the Bourdon tube; a pointer including a second shaft arranged on a side facing an outer periphery of the fan-shaped portion of the rotary piece; a first permanent magnet provided on an outer peripheral surface side of a fan-shaped portion of the rotary piece; a second permanent magnet provided at the second shaft. An outer peripheral surface of the first permanent magnet and an outer peripheral surface of the second permanent magnet each has N pole and S pole alternately magnetized at equal pitches. A magnetic member configured to relax force by which the second permanent magnet is attracted to the first permanent magnet is provided across the second permanent magnet from the first permanent magnet.
