摘要： The invention is characterized in that, when protrusion parts 30 are raised from a substrate W and the protrusion parts 30 are formed into spacers 12 with a predetermined outer diameter D and height H, the protrusion parts 30 are temporarily formed so as to have a diameter larger than a predetermined outer diameter D and a height larger than a predetermined height H, and the protrusion parts 30 are crushed, and leading end portions 30b of the protrusion parts 30 are protruded in a radially outward direction so as to have a double-layered structure, and then through-holes 35 are opened at the leading end portions 30b. Accordingly, the leading end portions 30b have strength due to a double-layered structure, and side portions 30a also have high strength due to contraction by pressing, whereby the sleeve-integrated member includes the entirely high-strength spacers 12.

摘要： The torsion beam for a suspension is formed of a hollow shaft having a cross section substantially of the shape of an inverted letter U. It, therefore, can be manufactured simply and is enabled to enjoy light weight and improved torsional rigidity. This torsional rigidity can be adjusted and the amount of offset of the joined parts of opposite wheel supporting members from the other component parts can be freely adjusted. The end plates are constructed of a plurality of mutually joined end plates and the torsion beam is joined by welding to the surface for mounting the beam after the end plates have been machined. Thus, the torsion beam type suspension is manufactured with a relatively simple equipment, with the result that cost of equipment and the cost of production are lowered. The torsion beam can be manufactured with increased simplicity by subjecting a flat plate to the steps for swelling, folding and joining opposed of the flat plate or superposing a first and a second plate severally formed in a structure having a cross section substantially of the shape of an inverted letter U.

摘要： An independent suspension provided with a knuckle for rotatably supporting a wheel thereon and a sub-knuckle member pivotally supported on the knuckle, the knuckle connected to the leading terminal of a lower arm through a first ball joint and the basal terminal part of the lower arm is attached to an automobile body. The leading terminal of an upper arm is connected to the sub-knuckle member through a second ball joint and the basal terminal part of the upper arm is attached to the automobile body side. The leading terminal of a control link attached to the automobile body side is connected to the knuckle member through a third ball joint. The axis which passes the centers of the first ball joint and the second ball joint constitutes itself a steering axis. The center of the third ball joint is offset relative to the point of intersection between the horizontal plane passing the third ball joint and the steering axis. As a result, the knuckle members are allowed to produce a swinging motion around the second ball joint as the center to change the camber angle of the wheel while the automobile body is being steered.

摘要： 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 2, wrapped cast except for a bonding portion 2b to a steel plate bonding member 3 upon molding a die-cast component 1, has a mold contact portion 4 at a boundary between a cast-in portion 2a wrapped cast with a die-cast component 1 and the bonding portion 2b. When a cast-in mold A is clamped, the mold contact portion 4 is brought into butting contact with the cast-in mold A, gap S between the cast-in member 2 and the cast-in mold A, cavity a, is closed.
