AXIALLY CENTERING APPARATUS FOR FUSION-BONDING OPTICAL FIBERS ABSTRACT OF THE DISCLOSURE An axially centering apparatus for fusion-bonding optical fibers comprising a pair of guides having long grooves on the upper surfaces thereof for engaging optical fibers, a pair of fulcra formed in parallel with the long grooves of the guides for supporting the guides, a pair of centering stands having substrates for supporting the fulcra, a pair of centering mechanisms having load imparting mechanism sections having telescopic output ends, load imparting mechanism sections, and transmitting mechanism sections for the adjusting mechanism sections so that the long grooves of said centering stands are disposed adjacently to each other to align in a rectilinear line, said centering mechanisms are associated with the centering stands to contact the output ends of the centering mechanisms with the guides of the centering stands, wherein said one centering stand satisfies the conditions that the fulcrum 3A and the long groove 4A are relatively positioned so that the crossing angle a (alpha) between a line segment AL1 and a perpendicular AL2 becomes 45°, where AO1 is the center of the fulcrum as seen from the plane perpendicular to the long groove, AO2 is the center of the long groove, AL1 is the line segment passing the centers AO1 and AO2, and AL2 is a perpendicular passing the center AO1 of the long groove, and similarly, the other centering stand satisfies the conditions that the crossing angle .beta. (beta) between a line segment LB1 and a parpendicular AL2 becomes 45°, where BO1 is the center of the fulcrum, BO2 is the center of the long groove, BL1 is the line segment passing the centers BO1 and BO2, and BL2 is a parpendicular passing the center BO1 of the long groove, and the pair of centering stands disposed adjacent to each other are perpendicularly crossed at both line segments AL1 and BL1, and the output ends of the pair of centering mechanisms are disposed on the same plane to be contacted with the guides of the centering stands.
