PROBLEM TO BE SOLVED: To provide a rotating drum for a washing device by which a spiral plate can be fixed in a cylindrical body without using welding and also the fixing operation can be easily performed.SOLUTION: A rotating drum provided in the present invention comprises a cylindrical body 2 having many water passage holes and a spiral plate 3 fixed in the inner peripheral surface of the cylindrical body 2 by a fixing fitting 4. The fixing fitting 4 has a cylindrical body abutting surface 4a which abuts on the inner peripheral surface of the cylindrical body 2 and a spiral plate abutting surface 4b which abuts on the side surface of the spiral plate 3. The spiral plate 3 is fixed in the cylindrical body 2 by fasteners 12 and 13 for fastening both the cylindrical body 2 and the spiral plate 3.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】溶接を使用することなく、円筒体内に螺旋板を固定することができ、しかも、その固定作業を容易に行うことができる洗浄装置用回転ドラムを提供すること。【解決手段】多数の通水孔を有する円筒体2と、円筒体2の内周面に固定金具4により固定された螺旋板3と、を備える。固定金具4は、円筒体2の内周面に当接する円筒体当接面4aと、螺旋板3の側面に当接する螺旋板当接面4bとを有し、締結具12,13にて円筒体2および螺旋板3の双方に締結されることにより、円筒体2内に螺旋板3が固定される。【選択図】図3
