Abstract
PURPOSE: To maintain the accuracy and strength as a watch and achieve the simplification and miniaturization of the structure by fixing a receiving body which is formed of plastic material and has protrusions coaxial to bearings and a support plate which is formed of a metal plate and engages to the protrusions.
CONSTITUTION: A receiving body 3 which is formed of plastic material such as plastics, etc. has at least 1 or more bearings 3a and are disposed with coaxial circular cylindrical protrusions 3c and 3d on the opposite side. An upper receiving plate 4 which is formed of a metal plate is opened with holes 4a, 4b for fitting to the protrusions 3c, 3d of the receiving body 3 and the receiving body 3 and the upper receiving plate 4 are firmly integrated by means of fitting of the protrusions and holes thereof. By combining the bearing body of plastics and the metal plate effectively in this way, variations in the distance between bearing centers owing to temperature differences may be virtually eliminated, and the watch may withstand stress at the mounting of the hands, thus the bearing bodies provided with multiple bearings may be realized, hence the reduction in cost may be achieved as well
