PURPOSE:To facilitate the assembling and to improve the gap accurately between the pole teeth of a pole and the pole teeth of a stator by providing holes radially of a carriage and providing roller bearings intregrally at both ends. CONSTITUTION:A carriage 4 is formed with a central hole 5 for movably engaging a stator 1 at the center, with a hole 6 at the side, with a pair of side plates 7 extended at both ends to form holes 8 at the side plates 7, with a shaft 9 supported to the holes 8, and with roller bearings 10 at the shaft 9 to movebly contact the bearings 1 with guide slots 3 to movably support the carriage 4. When thus constructed, a moveble body 11 can be radially mounted from the hole 6, and the carriage 4 can be simply mounted as copared with the conventional one. Since the bearings 10 are provided in the carriage 4 without intermediary of a support, the accuracy of a magnetic gap between pole teeth can be improved. |
