Claims

[Claims for Utility Model Registration] In a small motor in which two bobbins wound with coils are arranged coaxially on a stator yoke at a predetermined interval; the bobbin is a plastic part having integral flanges at both ends of a cylindrical part A terminal block is formed at a predetermined position on one flange, and a lead wire clamp section is formed at a position facing the terminal block on the other flange via a hinge section; The coil is connected to a terminal pin implanted in the terminal block, and a lead wire for external wiring is connected to the terminal pin; the two bobbins face the flange on the side having the terminal block. A structure in which the two lead wire clamp parts that are attached to the stator yoke and located on the outside in this state are combined with each other, and the lead wire connected to the terminal pin is sandwiched between the two clamp parts. The lead wire clamp portion has a groove into which the lead wire is press-fitted, and a convex piece for pressing the lead wire into the groove, and when the two clamp portions are combined with each other, one A terminal structure for a small motor, characterized in that the convex piece of the other clamp part fits into the groove of the other clamp part.
