1. An optical fiber fusion splicer which aligns tips of a pair of optical fibers and butts the tips each other, and fusion-splices core wires of the pair of optical fibers by discharge heating, comprising:
a pair of right and left V-grooved stands comprising V-grooves for butting the tips of the pair of optical fibers each other while positioning the tips of the pair of optical fibers; a pair of elastic members respectively supporting the pair of V-grooved stands, each of the elastic members comprising two elastically deformable plate-shaped members provided parallel to each other; a fixed base on which the pair of elastic members is mounted, whereby the pair of V-grooved stands is fixed thereto through the pair of elastic members, and which is long in a right-left direction; and a pair of micrometers aligning the tips of the pair of optical fibers by finely moving the pair of V-grooved stands with respect to each other while elastically deforming the pair of elastic members by pressing the pair of V-grooved stands from forward and backward directions, wherein: the pair of elastic members is provided so as to extend upward from fixing base portions of the fixed base while being respectively inclined in the forward and backward directions, and is disposed at positions shifted in the right-left direction of the fixed base; the pair of V-grooved stands is disposed such that the V-grooves provided therein communicate with each other; and when viewed from the right and left end portions of the fixed base, a distance L1 between first end portions of the pair of elastic members fixed to the fixing base portions is narrower than a distance L2 between second end portions of the pair of elastic members on which the pair of V-grooved stands is mounted. |
