Abstract
The present invention provides a reciprocating abrasion tester capable of conducting an abrasion test that exhibits small variations in evaluation even when conducted with respect to an automobile windshield glass using a wiper blade so as to conform to the actual abrasion conditions. This tester includes: a motor; reciprocating abrasion devices connected to the motor, and a loading member for applying load to the sliding member. Each of the reciprocating abrasion devices includes a crank, a reciprocating arm, and a sliding member for causing abrasion of a sample surface. Reciprocation cycles of the reciprocating abrasion devices differ from each other in phase.
