<p>PURPOSE: To provide the device which neither deforms large nor wears away much even when colliding or abutting against a string strike point adjustment part and sliding. CONSTITUTION: When a rod 2 is slid backward on the top surface 50a of a shelf plate 50 after maintenance to put the rod 2 back to its regular position, the peak surface 70b of a screw 70 collides against a wear-resistance abutting part 60, but the wear-resistant abutting part 60 is made of polyester and is recessed little. Even when a player steps in a soft pedal while the rod 2 is thus set to move the rod 2 as shown by an arrow R or releases the soft pedal to put the rod 2 back as shown by an arrow L, the surface 60b of the wear- resistant abutting part 60 is not recessed, so the friction between the peak surface 70b of the screw 70 and the surface 60b of the wear-resistance abutting part 60 is not large. The wear-resistant abutting part 60 itself has high wear resistance, so even when the soft pedal is operated repeatedly, the surface 60b never wears away.</p> |
