Abstract
A first groove and a second groove are formed deep in the top surface of a stationary housing; the second groove being extended by a given angle circumferentially from both ends of the first groove. A lock screw is threadedly installed to a screw receiving portion of the movable housing, and the movable housing is rotatably connected to the center of the stationary housing. In the housing space defined between the two housings, a flexible cable is wound and housed. The movable housing is positioned in the neutral position of rotation with respect to the stationary housing. This state is kept by engaging the tip of the lock screw with the first groove. To perform rotation tests of the movable housing, the lock screw is turned back up to the position in which the lock screw contacts both ends of the second groove, and the movable housing can be turned within a range of less than .+-.180 degrees from the neutral position of rotation. After completion of the tests, the lock screw is engaged with the first groove to re-lock the movable housing in the neutral position of rotation.
