Abstract

PURPOSE:To reduce overall length of the motor with a shorter rotary shaft while making it at a low cost by supporting one end of the rotary shaft with the bearing while the other end thereof is retained with an elastic shaft bearing being integrally constructed with the bearing base. CONSTITUTION:One end of the rotary shaft 1 is retained with the bearing running therethrough, the effective length of the bearing is set at more than twice the diameter of the shaft. The other end of the rotary shaft 1 is formed spherical at the tip thereof and retained with the elastic shaft bearing 10, which is composed of the elastic rib 11 integral constructed with the bearing base 4 and the concave surface 12 inside the elastic rib 11 is formed slightly larger than the spherical surface 13 of the shaft 1. With such an arrangement, overall length of the motor can be reduced with a shorter rotary shaft 1 while the motor can be less expensive as the number of the bearings is reduced to one. It can also stabilize the rotation and reduce the noise.
