Claim:
1. A mechanical splice unit comprising: a cable grasping member that grasps an optical fiber cable; a mechanical splice having an optical fiber guide groove that is formed at matching surfaces of both a base and a lid in a two-part-divided structure, the mechanical splice being capable of grasping an extended optical fiber at one end side of the lid, the extended optical fiber being drawn from a terminal of the optical fiber cable; a grasping member holding portion that movably holds the cable grasping member along a longitudinal direction of the mechanical splice; a first splicing tool comprising a first wedge that allows one end side of the lid of the mechanical splice to be in an opened state; a second splicing tool comprising a second wedge that allows the other end of the lid of the mechanical splice to be in an opened state; and an optical fiber splice auxiliary tool used for splice of the extended optical fiber that is grasped by the mechanical splice, wherein the optical fiber splice auxiliary tool includes: a mechanical splice grasping portion that holds the mechanical splice; and a guided portion that is slidable along a guide portion formed at a splicing tool to which an inserted optical fiber to be spliced to the extended optical fiber is fixed, and wherein the first splicing tool comprises a spacer that stops movement of the cable grasping member of the mechanical splice along the longitudinal direction thereof by a predetermined distance with respect to the mechanical splice; a front-end portion of the extended optical fiber is sandwiched between the base and the lid so as to be grasped and fixed therebetween by removing the first wedge from between the base and the lid of the mechanical splice; and the mechanical splice unit is capable of forming flexural deformation at the extended optical fiber between the cable grasping member and one end side of the mechanical splice in the longitudinal direction thereof as a result of causing the cable grasping member to further come close to one end side of the mechanical splice in the longitudinal direction thereof.
