Abstract
Official abstract text for this publication.
An electromagnetic valve has: a coil; a casing encircling the coil and having a cylinder portion and nail portions; a movable core moving axially in the wound coil; a fixed core set at an opening end of the casing; a valve body fixed to the opening end of the casing together with the fixed core by bending inwards the nail portions; and a spool valve body moving axially in the valve body. The nail portion is provided with a wide width portion at a root side, a narrow width portion at a top side and a stepped portion between the wide width portion and the narrow width portion. The stepped portion is positioned at a substantially same position as an outer edge of one end portion of the valve body, or positioned at a cylinder portion side with respect to the one end portion outer edge of the valve body.
First claim
