PURPOSE:To accurately attach an upper press-member in an easily detachable manner. CONSTITUTION:The title bonding device is provided with a retaining surface 51 formed on the upper surface of a retaining stand 50, a fixing piece 53 which is fixed to one side of the retaining surface, a press lever 57 which presses the upper press member 49 which is pivotally supported on the opposite side of the fixing piece on the retaining surface in a freely rotatable manner, a retentive strength energizing device 66 with which retentive strength is energized to the press lever 57, inclined surfaces 42 and 43 formed on both side faces of the upper side press member 40, and inclined surfaces 54 and 59 formed on the fixing piece and the press members. Accordingly, when the press lever 57 is energized by the retentive strength energizing device, the upper side press member 40 is press-connected to the retentive surface 51 and the fixing piece 53 by the component force generated on the inclination surface, and the upper side press member 40 is fixed to the retaining stand 50. The above-mentioned state of fixing is removed by the removal of energization of the retentive strength energizing device. As a result, the exhange operation of the upper side press member can be simplified when compared with the case where the upper side press member is screwed. |
