A lever assembly holds a wiper strip, which directly wipes a wiping surface. The lever assembly includes a plurality of levers, which are connected together in tournament style. An axial length of the lever assembly is shorter than an axial length of the wiper strip. A cover member receives the lever assembly, and opposed ends of the cover member hold the wiper strip. The cover member includes a plurality of cover portions, which are formed separately from one another.

A rotating shaft of a rotating machine is supported at its both ends by bearing bushes which are held in a frame of the rotating machine. The outer periphery of the bearing bush is rounded and held with a rounded surface formed on the frame, so that the rotational axis of the shaft and the bearing are self-aligned by rotation of the bearing bush. The inner bore of the bearing bush rotatably supporting the shaft therein is shortened by forming a relief bore, the diameter of which is larger than that of the inner bore. Because of this bearing structure, a natural vibration frequency of the shaft varies less, and, therefore, the rotating machine can be easily designed so that harmful noises due to the natural vibration are sufficiently suppressed.
