PROBLEM TO BE SOLVED: To automate cleaning work of an air element for an engine, and reduce human burden.SOLUTION: A slide part 2 slides an air jetting arm part 1 in cleaning an air element E, and one of a pair of arm members 11Aa, 11Ab, 11Ba, 11Bb arranged at a predetermined interval is positioned on an inner side of the air element E, and automatically performs the same work as the work that an operator cleans the inner side of the air element E by a predetermined air gun. At the same time, the other of the pair of arm members 11Aa, 11Ab, 11Ba, 11Bb cleans an outer side of the air element E; thus, the air element E can be cleaned at low cost with high efficiency.SELECTED DRAWING: Figure 1 |
