PURPOSE: A contact-type roll arrangement angle measuring apparatus used in a hot rolling mill is provided to measure a real arrangement angle and a dynamic displacement of a roll by installing displacement measuring sensors in a strip proceeding direction. CONSTITUTION: A contact-type roll arrangement angle measuring apparatus includes a hollow cylindrical moving rod(30), a hollow cylindrical upper casing(31), a hollow cylindrical intermediate casing(33), a hollow cylindrical fixing rod(38) and a lower casing(34). A probe(29) is detachably assembled to an upper end of the hollow cylindrical moving rod(30). The hollow cylindrical upper casing(31) is fixed to a housing through an outer bush(37). The hollow cylindrical intermediate casing(33) is detachably connected to the upper casing(31) and has a spring(41) therein for upwardly supporting the moving rod(30). The hollow cylindrical fixing rod(38) makes contact with an inner bush(36). The lower casing(34) is detachably coupled to a lower end of the hollow cylindrical intermediate casing(33).
