An assembly jib (70) for assembling a phase-modulation-type optical fiber gyro has a reel support area (80) for supporting a fiber coil reel (100) with an elongate optical fiber (10) wound therearound and a coupler reel (200) with optical fibers (16, 20) from a coupler (22) wound therearound, the fiber coil reel (100) and the coupler reel (200) being rotatably supported on a base plate of the assembly jig (70) through a support shaft (74). The assembly jig (70) also has a chip support base (76) disposed on the base plate for temporarily supporting thereon the optical IC chip (24) optically connected to the optical fibers (10, 16), a package housing support base (78A) disposed on the base plate for supporting a package housing (52) of a package to encase the optical IC chip (24) therein and substantially packaging the optical IC chip (24) with the package housing (52), and a lid support base (78B) disposed on the base plate for supporting a lid (58) to cover the package housing (52). The assembly jig (70) allows the optical fiber gyro to be assembly easily at a reduced cost. <IMAGE> |
