This invention reduces the amount by which members protrude to the outside
of a forceps for endoscope that can perform an oscillating operation, and
reduces the amount of contact between an organism and parts other than
the surgical instruments, thereby maintaining the visual field of the
endoscope. The forceps for endoscope comprises an insertion section that
is inserted inside a body cavity, an openable and closable forceps
section provided at the tip of the insertion section, and a operation
section for controlling the forceps section. The forceps section
comprises a first forceps member, and a second forceps member, which
faces the first forceps member and can rotate with a first pivotal
supporting member as a fulcrum; the second pivotal supporting member
supports the first forceps member from vertically above it so that it can
rotated freely around an oscillating operation axis member, and is
provided between the oscillating operation axis member and an
opening-closing operation axis member. A third pivotal supporting member
supports the first forceps member from vertically outside, so that it can
rotate around the oscillating operation axis member.
