PROBLEM TO BE SOLVED: To provide spherical bearings for a lock door, and the lock door provided with the spherical bearings for maintaining the smooth and accurate opening/closing operation of door bodies for a long period of time. SOLUTION: The non-powered type lock door 1 is provided with a pair of door bodies 2, the spherical bearings 6 for the lock door for supporting lower corner parts 4 of the door bodies 2, 3 respectively in a rotatable manner, and support parts 7 for supporting upper corner parts 5 of the door bodies 2, 3 respectively in a rotatable manner. The spherical bearing 6 is provided with a convex surface body 22 and a concave surface seat 24 coming in slidable contact with the convex surface body 22. The spherical bearing 6 is disposed downstream 16 of the support part 7 in a waterway 9 with respect to an X-direction to incline a rotating shaft C. COPYRIGHT: (C)2007,JPO&INPIT |
