ABSTRACT:
A tire building drum includes a hollow main shaft, a pair of bead lock sections arranged concentric with the main shaft and respectively holding a bead core of a tire, and a radially expansible/contractible carcass-supporting body defining an inner shape of a carcass member extending between the bead cores. The carcass-supporting body is composed of a pair of core bodies which are concentric with the main shaft and have a plurality of expansible/contractible rigid segments circumferentially abutting on and engaging with each other. The tire building drum is provided with a pair of sliders on which the core body and the bead lock section are mounted on a single side in the axial direction, slider-moving means for moving these sliders to any required radial position and segment-expanding/contracting means for expanding/contacting the segments of each core body to any required radial position.
