BLADE RUBBER FOR WIPER PERFORMANCE EVALUATION AND PERFORMANCE EVALUATION METHOD OF WIPER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a blade rubber for wire performance evaluation which enables reproducible pressure measurement.;SOLUTION: Evaluation rubber 30 comprises: a base part 31 held by a holding part 14a (a yoke lever 14); and an elastic contact part 35 which is integrally formed with the base part 31 and is formed so as not to incline relative to the base part 31. The elastic contact part 35 is vertically placed in press contact with a pressure sensor S and the pressing force is measured. Then, the wiper performance, that is, the appropriateness of the pressing force to a sweeping surface G of a blade rubber for sweeping is evaluated based on the measurement result.;COPYRIGHT: (C)2014,JPO&INPIT
