<P>PROBLEM TO BE SOLVED: To provide an antiskid plate, which is improved in mounting strength and a sound absorption (a damping) effect. <P>SOLUTION: A rubber antiskid plate 1 is stretched on a steel walking surface or working surface such as a passage or a floor for a working vehicle. The antiskid plate includes a surface side sheet 10 formed with antiskid protrusions 12, and a rear side sheet 20 mixed with permanent magnet powder 22 throughout a whole area. Since the antiskid plate is made of rubber, impact during walking is mitigated and walking noise is suppressed by its elasticity. In comparison with the antiskid plate partially with an attraction face, since the attraction face is on the whole area of the rear face, the mounting strength is improved, and since magnet powder exists on the whole area of the rear face and the whole area contacts the walking surface, sound generated from a steel plate is transmitted to a whole area of the antiskid plate, and it is effectively absorbed by vibration of the magnet powder (metal powder). Both sheets are vertically joined together throughout a whole area, and since a whole circumference end face of the rear side sheet is covered by a whole circumference of the surface side sheet, risk of a circumferential edge of the rear side sheet 20 peeling off becomes small, and separation of both sheet rims is minimized. <P>COPYRIGHT: (C)2013,JPO&INPIT |
