Claim:
An insert rapier that is used for a both-side rapier loom and transfers a weft to a carrier rapier, the insert rapier comprising: a rapier head having a bottom portion; and a weft-holding portion provided at the bottom portion of the rapier head, wherein the rapier head includes hill-like rear and front walls provided at a distal side of the rapier head with respect to the weft-holding portion and protruding upward from both sides of the bottom portion of the rapier head, and a tongue piece extending from a position closer to the weft-holding portion than the rear and front walls to a region between the rear and front walls, wherein the front and rear walls partly overlap with one another in a side view of the rapier head, wherein a distal tip of a distal portion of the tongue piece is located in the overlapping region; an upper ridge of the distal portion of the tongue piece gradually ascends from the distal tip of the tongue piece toward a proximal side of the tongue piece; and the front wall, the rear wall, and the tongue piece define a warp-dividing portion, and wherein the tongue piece of the insert rapier is movable from a standby position to a retracted position, which is above the rapier head or at a distal side of the rapier head, in the side view of the rapier head; and the tongue piece is moved to the retracted position before the weft passes the distal tip of the tongue piece.
