加熱後、支持棒３２を矢符５２の反対方向に変位させて
ヒータ１０を取外し、操作杆３０を矢符５１の方向に一
定角度だけ再度回動させる。After heating, the support rod 32 is displaced in the direction opposite to the arrow 52, the heater 10 is removed, and the operating rod 30 is again rotated by a certain angle in the direction of the arrow 51.

そうすることによって、分岐サドル２の融着部２ｂと分
岐管３の融着部３ａとが、前述と同様にほぼ一定の圧接
