A catcher(30) is installed at the end of the arm, and includes a stopper formed at the inner center of a body, an electromagnet installed at the inner end of the body, and a spring. A holder is inserted into the catcher, and includes an electromagnet and a permanent magnet elastically supported by the spring. An oil-feeding tank(10) is installed at the holder and contains lubricant. And, the oil-feeding tank includes a nipple and a permanent magnet opposite to the electromagnet in the holder.
