Pressure device for tire constituent member which easily performs the individual pressure control of the plurality of pressure rolls while restraining the structure of the pressure device pressurizing the tire constituent member by the plurality of pressure rolls from becoming complicated. Each of a plurality of pressure rolls (12) is displaced around the shaft member (20) and pressurizes the tire constituent member (2) . Each of a plurality of supporting parts (14) supports the pressure roll (12) rotatably from the inside of the pressure roll (12) and is displaced integrally with the pressure roll (12). A plurality of pressure holes (21) are formed in a plurality of points of the shaft member (20) corresponding to positions of the plurality of pressure rolls (12) so as to extend in the pressurization direction (P) for the tire constituent member (2). Each of a plurality of moving members (15) projects in the pressurization direction (P) from the pressure hole (21) so as to pressurize the pressure roll (12). Each of a plurality of supply pipes (17) is arranged in the inside space (30) around the shaft member (20) so as to each supply the pressurizing medium for pressurizing the moving member (15) into the pressure hole (21). |
