PURPOSE:To obtain the titled rotary drum high in the reliability by using an annular partition body capable of sticking tightly to the rotary drum in a join part of both the rotary drum and the annular partition body stuck to the rotary drum. CONSTITUTION:In a crosssectional shape of an annular partition body 2 tightly stuck to the inside surface of a rotary drum 1, an outside periphery part namely the part tightly stuck to the inside surface of the rotary drum is thick-walled in comparison with the inside periphery part as the wall thickness in the direction of a rotating shaft 1a. As a result, since the deformation of the annular partition body 2 can be followed to the deformation of the radius direction of the rotary drum 1 in a period of the rotation, such the trouble can be prevented that the excessive load is charged on the rotary drum 1 or adversely that a clearance is caused between the rotary drum 1 and the annular partition body 2 or that the partition body 2 is separated. Therefore the rotary drum made of a composite material of a centrifugal separator having the high reliability is obtained.
