PURPOSE:To well fix and held a flange by providing a flange by which elastic pieces provided in the both edges of a drum are brought into pressure-contact and fixed in the inwall of the drum and providing a means which adjusts the pressure-contact power and the direction of the elastic pieces. CONSTITUTION:A drum heater 2 is contained inside the drum 1, and the flange 3 is fitted inside the edging part of the drum 1. Then, the elastic piece 8 is inserted into the through hole 6b of the circumferential part 6 of the flange 3 and an assembling screw 9 is inserted into a fitting hole 8a and screwed lightly in a female screw part 4. In the next place, an adjustment screw 10 is screwed in a screwing hole 8b and the tip of the adjustment screw is abutted on the peripheral wall part of an embossed part 5. Thus the elastic piece 8 is moved in an arrow direction and the edging part is brought into pressure- contact in the inwall part of the drum 1. After that, the screw 9 is clamped tightly. Thus, since a screw 10 is prepared, the pressure-contact power of the elastic piece 8 with respect to the inwall surface of the drum 1 is adjusted by screwing amount, and also the directionarity can be adjusted compulsorily. |
