Title:
CYLINDRICAL DC MOTOR
Document Type and Number:
Japanese Patent JP3192131
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To attach a cylindrical DC motor to a fixed location so as to reduce its occupation volume when mounting it on some portion and to make invariable its attachment position, by not using a holder which may make its outer diameter substantially large.
SOLUTION: Forming a housing H out of a cylindrical case 1 and an end bracket 2 fitted engagingly into the opening portion of the case 1, a step portion 1a having a smaller diameter than the outer diameter of the case 1 is provided in the end portion of a side opposite to the end bracket 2 for holding a cylindrical DC motor by an eccentric weight W squeezed into its centrally protruded output shaft S. In the step portion, using as a guide 3a an attachment ring 3 of its one portion being protruded outward, it is so mounted in the case 1 by its squeezing, etc., as not to protrude it from the outer diametrical portion of the case 1, except for its side of the guide 3a. Its attachment position is determined so as to receive the end surface of a magnet M by a stage portion 1b formed in the inside of the step portion 1a.
