The cross-sectional shape shown by the arrow AA line in FIG. 1 forms a cross shape as shown in FIG. ing. Since the operating shaft 21 has a cross-shaped cross section, when the knob 2 is rotated, both the moderator 5 and the movable platen 3 can be rotated in conjunction with the operation of the knob 2. And, when the knob 2 is tilted, only the movable platen 3 can be moved on the pole plate 4 in conjunction with the operation of the knob 2, and the cross-sectional shape is a cross structure. The mechanical strength of the movable platen 3 can be ensured even if the thickness of the operation shaft 21 is set to such a small thickness that sink marks do not occur during molding. Further, the operation shaft 21 has two projecting portions 22, 22 projecting to the side, and the support 6 described later is fixed to the operation shaft 21 with one touch by using the projecting portions 22.
