PURPOSE:To provide a center position measuring apparatus capable of measuring the fluctuations of the center position of an upper mold attaching member in the stroke of said member. CONSTITUTION:A center position measuring apparatus is constituted of the hollow cylindrical member 1 concentrically provided to an upper mold attaching plate 11 in a suspended state, the columnar member 2 concentrically erected on a lower mold attaching member 13 and having height H equal to or more than the stroke S of the upper mold attaching member 11 from the holding position (1) of a green tire due to upper and lower molds to the closing position (2) of both molds and inserted in the hollow part 1a of the hollow cylindrical member 1, the non-contact type distance sensors 3, 4 attached to the hollow cylindrical member 1 with respect to the columnar member 2 and a recorder 5 recording the fluctuations of the measured values of the non-contact type distance sensors 3, 4 when the upper mold attaching member 11 is raised and lowered. |
