PURPOSE:To prevent the abnormal noise and the breakage of subject machine which will be generated by the vibration of metals which come in contact eath other by a method wherein the packing of an elastic substance is inserted between the cylindrical material of the air filter and the member to be detachably press-fitted to the end section of said cylindrical material. CONSTITUTION:The base plate 3a, which has been formed in such manner that it is covering the inspection hole 1a provided at a section on the frame of a motor 1, and the air filter 2, having the inner cylinder 3b standing upright on the base plate 3a and cylindrical material 3c, are detachably installed at the inspection hole 1a using a hook 2a. Then, the elastic packing 11 is fitted in between the cylindrical material 3c of the air filter 2 and a wire netting 6, to be detachably press-fitted to the end section of the cylindrical material 3 on the entire circumference of the upper edge of the cylindrical material 3c. Through these procedures, the entrance of waste paper and the like from the gap between the wire netting 6 and the cylindrical material 3c can be prevented, thereby enabling to eliminate the generation of the abnormal noise and the breakage of the machine due to the vibration caused by the motor in operation. |
