To provide a target installation jig capable of accurately attaching targets to be used when measuring creepage to upper surfaces of rail and sleeper.SOLUTION: A target installation jig for creepage measurement mounted on a railway track sleeper and used to attach a plurality of targets in a state having prescribed offsets at positions distanced from an upper surface of the sleeper and an upper surface of a flange on a lower part of a rail, includes: a body (31) arranged so as to straddle the rail; a protruded part (31d) extending from the body to a side of the rail next to the sleeper; and a positioning part (33) that abuts a prescribed part of the sleeper and provides a reference for positioning at least in a longitudinal direction of the sleeper. The body has a pair of legs in contact with the upper surface of the sleeper, and openings (31b, 31c, 35a) each having a shape corresponding to a target having a prescribed shape are formed in at least one of the pair of legs and a prescribed part of the protruded part.SELECTED DRAWING: Figure 4

    【課題】ふく進を測定する際に使用するターゲットをレール及び枕木の上面に精度よく貼付することができるターゲット取付け用治具を提供する。【解決手段】鉄道軌道の枕木上に載載され、枕木の上面およびレール下部のフランジの上面の枕木から離れた位置に所定のオフセットを有した状態に複数のターゲットを貼付するためのふく進測定に用いるターゲットの取付け用治具において、レールの上を跨ぐように配置される本体部(31)と、この本体部から枕木の横であってレールの側方へ延設する張出し部(31d)と、枕木の所定部位に当接して少なくとも枕木の長手方向に対する位置決めの基準を付与する位置決め部(33)とを備え、本体部は枕木の上面に接する一対の脚部を有し、当該一対の脚部の少なくとも一方及び張出し部の所定部位に、所定の形状を有するターゲットに対応する形状を有する開口部(31b,31c,35a)を形成した。【選択図】図4
