CLAMPER AND IN-WATER-CHAMBER OPERATION DEVICE

A clamper (23) includes a clamp mechanism (231) which inserts an insertion portion (2311a) into a tube member and clamps the tube member and a lifting and lowering mechanism (232) which lifts and lowers the clamp mechanism (231) in the insertion direction of the insertion portion (2311a). The clamp...

Beschreibung
Zusammenfassung:	A clamper (23) includes a clamp mechanism (231) which inserts an insertion portion (2311a) into a tube member and clamps the tube member and a lifting and lowering mechanism (232) which lifts and lowers the clamp mechanism (231) in the insertion direction of the insertion portion (2311a). The clamp mechanism (231) includes a clamp body (2311) which has the insertion portion (2311a), a cotter (2312) which protrudes from the insertion portion (2311a) to come into friction-contact with the tube member and is movable in a reciprocating manner in the insertion direction of the insertion portion (2311a), a piston rod (2313) which presses the cotter (2312) so that the cotter protrudes from the insertion portion (2311a) when being pulled toward the opposite side to the insertion direction of the insertion portion (2311a), and a rod cylinder (2315) which is integrated with the clamp body (2311) and pulls the piston rod (2313).
