A permanent magnet rotor includes: a rotor core of a laminated structure about a rotation shaft; a plurality of permanent magnet embedment slots provided to the rotor core at equally spaced positions from the rotation shaft; and permanent magnets inserted into the respective permanent magnet embedment slots. The permanent magnet embedment slots each have a magnet storing portion and a buffer and other members storing portion continuing to the magnet storing portion. One permanent magnet is stored in the magnet storing portion and a buffer member and a pushing member used to fix the permanent magnet are stored in the buffer and other members storing portion. It thus becomes possible to provide a permanent magnet rotor capable of not only preventing damage on a permanent magnet by reducing resonance even when the magnet resonates under a vibration condition, but also enhancing mass-productivity.

A transfer conveyor which prevents collisions between works to be conveyed when the works to be conveyed or stored are carried on a conveyer track by a work support having a length shorter than the length of works to be conveyed, which permits reverse traveling during maintenance operations and the like. The collision preventing mechanism includes a sensing element which is biased into a contact position where it engages a leading work support on the conveyor track and is deflected, a sensing lever 132, which mounts the sensing element and pivots in accordance with the contacting/deflecting operation of the sensing element, and a stopper lever downstream from the sensing element, which is connected to the sensing element to be displaced into the path of travel of the next trailing work support when the sensing element is in the contacting position, The stopper lever limits the travel of the trailing work support to a predetermined storage conveying interval.

The concentrated winding coil is mounted onto a tooth such that a coil end portion is housed inside a concave space that is formed by the trunk portion and first and second guide portions at two axial ends of the tooth. Third cover portions of an insulating sheet that is disposed on two circumferential sides of the tooth are folded over so as to overlap with each other and extend so as to cover the coil end portion of the concentrated winding coil, and a second leader line that projects outward from a radially inner end portion of the concentrated winding coil is bent and led radially outward parallel to the coil end portion that is covered by the third cover portions.
