Abstract
A forceps of endoscope comprises a clip that is provided with at least three arms and a base end portion. The arms are connected to the base end portion. Each of the arms has an open-close deforming portion located close to the base end portion. A core member is provided inside the clip to be in contact with an inner surface of the open-close deforming portion at least when the arms are open. A clip open-close ring is operated by remote control performed from the base end of the sheath. The clip open-close member is engaged with the open-close deforming portion to open and close the arms with a substantially equivalent angular interval and so as to prevent each of the arms from crossing each other.
