A projection of burr is provided by forming an appropriate gap to set a cast-in member to a cast-in mold, completely closing the gap when the cast-in mold is clamped, and correcting cast-in positioning (axis mating) to a die-cast component by a clamping operation of the die-cast mold, regardless of a dimensional precision of the cast-in member upon a manufacture. Steel plate cast-in member, wrapped cast except for a bonding portionto a steel plate bonding memberupon molding a die-cast component, has a mold contact portionat a boundary between a cast-in portionwrapped cast with a die-cast componentand the bonding portion. When a cast-in mold A is clamped, the mold contact portionis brought into butting contact with the cast-in mold A, gap S between the cast-in memberand the cast-in mold A, cavity a, is closed.

A door operating apparatus for a vehicle back door is comprised of a wire, a winding mechanism, a guide pulley, a tension mechanism and a stopper. The winding mechanism is installed at one of a vehicle body and the back door and is connected to an end of the wire. The winding mechanism winds and releases the wire according to a command signal. The guide pulley is installed at the other one of the vehicle body of the back door with respect to the winding mechanism and supports the wire. The tension mechanism is connected to the other end of the wire and always pulling the wire. The stopper prevents the wire from being sent from the tension mechanism at a predetermined point. Therefore, even if the back door is manually opened and closed, the wire is kept in a tensioned state by means of the tension mechanism to enable smooth opening and closing during manual operations.

Door operating apparatus for vehicle

Disclosed herein is an air spoiler device which comprises a base member; two rail members secured to the base member and extending in parallel with each other; two sliders slidably and respectively engaged with the rail members, so that each slider is slidable forwardly and rearwardly along the corresponding rail member; two supporting leg units respectively mounted on the sliders; a spoiler fin mounted on the two supporting leg units; and a drive for moving the sliders forwardly and rearwardly along the rail members.
