摘要：
A lubricant deterioration detecting device has a light emitting unit and a light receiving unit so arranged as to define a gap therebetween for accommodating a lubricant forming an object to be detected, and a determining circuit for determining a light transmittance of the lubricant in reference to an output from the light receiving unit to thereby detect a status of deterioration of the lubricant.
