リング整形凹所23の円弧面24ａに沿って当接する。When the position of the O-ring 9 is determined, as shown in FIGS. 3 and 4, the shaping pressing members 14, 14 are moved in the directions toward each other, and the O-ring shaping recesses 23, 23 are moved. The O-ring 9 is sandwiched from the left and right so that a hole having the same diameter as the outer shape of the O-ring 9 is formed on the arcuate surfaces 24a, 24a, and the outer shape is surrounded. As a result, the outer shape of the O-ring 9 becomes O.
It abuts along the arc surface 24a of the ring shaping recess 23.
【００２８】従って、Ｏリング９の全体が非円形状に変
形していても、外径側に弯曲等した部位がＯリング整形
凹所23にて内径側へ押圧されるので、自動的に円形状に
整形（矯正）され、同時に、高精度で位置決めも行われ

の逃げ（反り）を防止できるので確実かつ安定した整形
が可能となる。Therefore, even if the entire O-ring 9 is deformed into a non-circular shape, a portion of the O-ring which is curved outward is pressed by the O-ring shaping recess 23 toward the inner diameter, so that the O-ring 9 is automatically circular. The shape is corrected (corrected), and at the same time, positioning is performed with high accuracy. At this time, since the inclined arc surface 24b can prevent the O-ring 9 from escaping (warping) upward, reliable and stable shaping can be performed.
【００２９】そして、Ｏリング９を整形押圧体14，14に
て挟みこんだ状態のままで、上記シャッタを開き、図５
に示すように、搬出部材４の保持部10をＯリング９内に
挿通し、Ｏリング９を保持部10に弾性保持する。Then, while the O-ring 9 is still sandwiched between the shaping pressing members 14 and 14, the shutter is opened, and as shown in FIG.
As shown in, the holding portion 10 of the carry-out member 4 is inserted into the O-ring 9, and the O-ring 9 is elastically held by the holding portion 10.
【００３０】このとき、海綿状体17に保持部10が接触し
