この発明は、二つの部材の一方に対しては圧入し、他方
に対しては揺動あるいは回動自在にピン連結、する回動
継手部などに用いられる圧入ビンに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a press-fit bottle used in a rotary joint, etc., which is press-fitted into one of two members and connected to the other with a pin so as to be swingable or rotatable. .
二つの部材を揺動あるいは回動自在に連結する、たとえ
ばヒンジ構造にあっては、連結手段と 。For example, in a hinge structure that connects two members in a swingable or rotatable manner, it is a connecting means.

可に遊嵌合されている。そして、圧入ピンとビン孔との
固着は一般にセレーション結合により行なわれている。In many cases, a press-fit pin is used, and this press-fit pin is fixed by press-fitting a part into a bottle hole drilled in one member, and is fixed in a bottle hole drilled in another member. Rotatably loosely fitted. The press-fit pin and the bottle hole are generally fixed by serration bonding.
しかしながら、セレーション結合にあっては、圧入ピン

から抜は出すおそれがある。However, in the case of serration connection, the process of forming fine serration grooves on the circumferential surface of the press-fit pin is relatively expensive, and the serration grooves formed on the circumference of the press-fit pin are parallel to the axis, so it is difficult to continuously process the serrations. Due to use, there is a risk that the press-fit pin and the bottle hole may become misaligned in the axial direction, or that the press-fit pin may come out of the bottle hole.

Articles, total 4
It is made up of rows. The press-fitting rib 3 extends over the entire length of the tapered shaft portion 2 from the continuous portion 4 of the perfectly circular shaft portion l and the tapered shaft portion 2 to the other end of the tapered shaft portion 2. The press-fitting rib 3 has one end 3a located at the continuous portion 4, and the other end 3b located at the large diameter end of the other end of the tapered shaft portion 2.
This reduces the press-fitting resistance at the initial stage of press-fitting when the press-fit pin is press-fitted into the pin hole 7 of the member 6 to be fixed (see FIGS. 9 and 10), and also reduces the inner circumferential surface of the pin hole 7 of the member 6. In order to smoothly press the press-fit rib 3 into the
It has relatively gentle arcuate slopes 3a' and 3b',
The phloem 3C of the press-fit rib 3 has circular arc-shaped inclined surfaces 3a', 3b'
It is substantially parallel to the tapered surface 2a of the tapered shaft portion 2 between them. Therefore, the press-fitting ribs 3 each converge at one end with respect to the axis 0 in synchronization with the tapered shaft portion 2, and gradually expand toward the large diameter portion at the other end.

It is. Further, the number of press-fit ribs 3 protruding from the tapered shaft portion 2 is not limited to four as in the illustrated embodiment, but may be provided in a plurality at equal intervals in the circumferential direction.

One converging side end 3', which is the starting point of the press-fitting rib 3, extends beyond the continuous portion 4 to the perfectly circular shaft portion l. That is, the press-fitting rib 3 extends from the large diameter end of the tapered shaft portion 2 to beyond the small diameter end thereof to the perfect circle shaft portion 1.

となり、圧入ピンは部材６に確実に固着される。9 and 10 show a state in which the press-fit pin according to the first embodiment of the present invention shown in FIGS. 1 to 4 is press-fitted into the bottle hole 7 of the member 6 to be fixed and fixed. When press-fitting the press-fit pin into the pin hole 7 of the member 6, the press-fit pin is first inserted into the pin hole 7 of the member 6, which has an inner diameter that is approximately the same as the outer diameter of the perfect circular axis fill of the press-fit pin. When press-fitting is performed from the right side in Fig. 9, the converging side end 3a of the press-fitting rib 3 first enters the inner circumferential surface of the bottle hole 7, and as the press-fitting progresses, the tapered shaft portion 2 and the tapered shaft portion 2 whose diameter gradually increases toward the larger diameter side. The press-fitting rib 3 gradually bites deeply into the inner circumferential wall of the bottle hole 7 (while obtaining the so-called wedge effect), and at the same time, each divided circumferential surface 5 of the tapered shaft portion 2
It also bites into the scrap surface inside the pin hole 70. The material pushed away by the press-fitting ribs 3 is pushed into each divided circumferential surface 5 that gradually expands between each press-fitting rib 3. When the press-fitting is complete, each press-fitting rib 3 and each divided circumferential surface 5 close to each other in the bottle hole 7. The press-fit pin is bitten into the inner circumferential surface, and the press-fit pin is securely fixed to the member 6.
