が低下してしまう本部会があった。A conventional ball joint type piston is, for example, one in which a piston body (1) and a spherical bearing body (2) are integrated as shown in FIG. 1, or a piston body (15 and A structure in which the spherical bearing bodies (6) are separate is known.By the way, the spherical bearing bodies (2), (2) have pole studs (6) fitted into their spherical seats (3). 4) Oil hole (for 11m1t with ball part (5)
6), but in the case of the structure shown in Figure '41, the drilling process is extremely difficult, and in the case of the structure shown in Figure 2, the spherical seat There was a meeting where (2) had to be fixed to the piston/main body (15), which resulted in an increase in the number of modifications, resulting in a decrease in productivity.

ものである。The present invention has been made in view of the above circumstances, and the ninth aspect of the fitting process is to form one or more slits in the spherical seat before molding and then fit the ball part, thereby improving processing efficiency. This is what I did.
以下、実施例を示す図面に基いて本発明を説明する。EMBODIMENT OF THE INVENTION Hereinafter, this invention will be explained based on drawing which shows an Example.

）。Figures 3 to #15 show the main steps of the present invention, and show that the spherical bearing Q (I is cold-molded in advance, and the upper part has a cylindrical shape and is integrated with the piston body I). When forming the cold seal, a spherical surface 1 is formed on the upper side wall of the spherical bearing body.
m (two slits (xaa) that open on the upper surface α of 1G and face parallel to the axis of the piston body (11)
, (tab) are formed simultaneously. Next, after tightening the tip ball part a of the pole stud a fathom into the spherical seat a of the spherical bearing body, the upper cylindrical part a1 of the spherical bearing body part is formed into a ball part (c) using a compression molding method or the like. The upper ends of (13M) and (13b) touch each other or are close to each other and the upper ends of (131) (131)

の実用上火きな効果を奏することができた。As described above, the piston body and the spherical bearing body -1: By simultaneously forming a slit on the spherical bearing body during body molding, and then fitting the ball part of the cylindrical stud into the spherical seat by compression molding. , the slit part is filled with oil)
It goes without saying that the number of steps is reduced compared to the conventional method of drilling oil holes in a post-process.In addition, conventional oil-filled machining using integral molding was often done by electrical discharge machining, but with this method, The machining time used to be 30 to 60 seconds l/10
Furthermore, by forming the slit, it was possible to produce significant practical effects such as facilitating plastic working for fitting the ball part.
なお、上記実施例ではスリットを二本対向して設は九が
、これに限定されることなく一以上であればよい。In the above embodiment, the number of slits is nine, but the number of slits is not limited to this, as long as the number of slits is one or more.
