PROBLEM TO BE SOLVED: To advance/retreat an apparatus for washing the inside in a roll shell without relying on manpower of a worker, when washing the inside of a cylindrical body such as the roll shell of an existing suction roll, with a simple structure.SOLUTION: A support plate 5 is turnably provided on a direction change shaft 4 (illustrated in Fig.2) on a trestle plate 2, and paired rollers 7 are rotatably supported on a roller shaft in a direction parallel to a surface of the trestle plate 2 by the support plate 5. A support object bar body 8 is placed on and supported by the paired rollers 7 and 7, and the support object bar body 8 and the direction change shaft 4 are crossed at a right angle in this case. When the direction of the roller shaft exists in a torsional position with the support object bar body 8, since a direction of component force by rotation of the rollers 7 and 7 becomes the axial direction of the support object bar body 8, the support object bar body 8 moves in the axial direction by this force. The movement direction of the support object bar body 8 is changed by the direction of the roller shaft. |
