ABSTRACT:
A grease supply confirming device confirming the supply of a grease into a bearing, according to the present invention includes a detecting member an elastic supporting member and a movable body. The movable body such as a metal spherical body is movably provided in a piping through which a grease to be supplied flows. The elastic supporting member is provided in the piping for supporting the movable body. The detecting member such as an eddy current type displacement sensor detects to see whether or not the grease is supplied in accordance with the displacement of the movable body. The grease supply confirming device further includes an abnormality judging circuit connected to the detecting member for judging the abnormality in grease supply, and an outputting portion for outputting an alarm according to the instruction from the abnormality judging circuit.
