A passive compliance gripper includes a passive compliance part, a displacement measuring element and a gripper mount. A first end of the passive compliance part is fixed, and a second end of the passive compliance part is configured to be transformed. The displacement measuring element is equipped to the passive compliance part, and measures displacement due to transformation of the passive compliance part. The gripper mount is connected to the second end of the passive compliance part, and has a gripper part gripping a component.

Disclosed is a magnetic bearing structure including a permanent magnet, levitating a rotation body without a bias current, and easily magnetizing the permanent magnet. The magnetic bearing structure includes a ring-shaped permanent magnet provided on a side of a rotation shaft and magnetized in a direction parallel with a shaft direction of the rotation shaft, a coil installed on a side of the permanent magnet, and a conductor installed on an external side of the coil and used to form a magnetic field path. According to the configuration, when an additional bias current is not supplied to the coil installed in the magnetic bearing, a rotation body levitates according to the magnetic field caused by the permanent magnet, and a magnetized direction of the permanent magnet is in parallel with a shaft direction of the rotation shaft thereby allowing easy magnetization and increasing productivity of the magnetic bearing.
