PURPOSE:To measure endurance property readily from the magnitude of noise voltages, by compressing the sliding piece of a slider to the resisting body of a sample, reciprocally turning the sliding piece by a turning device, and measuring the sliding noises with the sliding piece being slidden after a specified sliding times are reached. CONSTITUTION:A sliding-noise measuring device 1 comprises a slider 2 and a noise measuring device 3. The slider 2 has the following parts: an attaching plate 41, to which a sample is attached; a digital counter 33, which can set a sliding piece (not shown) up to the maximum sliding times of 9,999; a running and stopping switch 34; a reset button 35; a sliding speed switch 36, which can changes the sliding speed into three stages of 1,800, 1,000, and 600 times per hour; and the like. The measuring device 3 has the following parts: a voltmeter 53; a voltage selecting switch 54; a noise voltmeter 55; a measuring range selecting switch 56, which sets the voltmeter 55 to the full scales of 1,000, 100 and 10mV; and the like.
