Abstract
A terminal connection structure of an electromagnetic coupling device includes terminal housing unit, an extraction hole, a flat contact portion, a conductive mount member, and a conductive support member connected to a power source lead line. The terminal housing unit is formed integrally with a resin coil bobbin having an electromagnetic coil therein, and projects from a through hole formed in a yoke having an annular groove in which the resin coil bobbin is press-fitted. The extraction hole is formed in the terminal housing unit to extract one end of a winding of the electrogmagnetic coil. The flat contact portion is formed between a pair of grooves formed on two sides thereof in the terminal housing unit, and one end of the winding extracted from the extraction hole is brought into contact with the flat contact portion. The conductive mount member is press-fitted in one groove of the terminal housing unit to hold a portion of the winding brought into contact with the flat contact portion. The conductive support member is press-fitted in the other groove of the terminal housing unit to hold another portion of the winding brought into contact with the flat contact portion, and abuts against the mount member to hold press-fit states of the both.
