On a front edge plane of the above mentioned the other mirror-surface plate, the bush (55) is arranged inner than an area for forming a clamp area in a diameter direction. In this case, since an area of a front edge plane of the bush (55) becomes small, molding object cooling performance is prevented from deteriorating.
