Electromagnetic Valve and Fixing Structure

An electromagnetic valve comprising:

• an annularly-wound coil;
• a casing that encircles an outer peripheral side of the coil and has
• (a) a cylinder portion, at least one end side in an axial direction of which is open;
• and
• (b) a plurality of nail portions which are formed integrally with the opening end of the cylinder portion,
• a movable core that is housed movably in the axial direction in an inner periphery of the coil;
• a fixed core that is set at the opening end side of the casing;
• a hollow valve body that is fixed to the opening end of the casing together with the fixed core by bending inwards and deforming the nail portions;
• and
• a spool valve body that moves in the axial direction in the valve body according to the movement in the axial direction of the movable core, and
• the nail portion being provided with
• (c) a wide width portion formed at a root side of the nail portion;
• (d) a narrow width portion formed at a top edge side of the wide width portion;
• and
• (e) a stepped portion formed between the wide width portion and the narrow width portion, and
• the stepped portion being positioned at a substantially same position as an outer edge of one end portion of the valve body which abuts on the fixed core from the axial direction, or being positioned at a cylinder portion side with respect to the one end portion outer edge of the valve body.
