摘要:
A probe (20) has a holder (21) with a small-diameter portion- (25) and a stepped surface (33) at a base end of the small diameter portion (25). The stepped surface (33) is recessed over the entire circumference of a base end of a small-diameter portion (25) to form a groove (40) and an inner corner of the groove (40) is rounded. The probe (20) is mounted by resiliently pressing the stepped surface (33) against the edge of a mount hole (15) in a base plate (13) of a brake shoe (12). A bending force acts on the small-diameter portion (25) of the holder (21) due to the sliding contact of the brake drum (10). However, the rounded portion (41) at the bottom of the groove (40) avoids a stress concentration on an inner corner of the base end of the small diameter portion (25).
