Abstract

PURPOSE: To make motor structure thin and stabilize its magnetic circuit by forming different or same magnetic members in one body using joint forms.
CONSTITUTION: A convex is formed in either two different or same magnetic members to constitute the magnetic circuit section of a clock motor which is used in such compact watches as wrist watches, for example, in the magnetic member 1 of a winding section and a concave is formed in the magnetic member 2 to constitute a closed magnetic circuit. By punching both these convex and concave with a proper tightening margin, the magnetic circuit section in one body is formed. This permits two magnetic members to eliminate the need for their overlapping sections and to be made thin. Simultaneously, such troubles as the deterioration of magnetic characteristics due to contact failure can be removed.
