Claims

[Scope of utility model registration request]

Consisting of grooves arranged in the rail perpendicular direction on the part body and extending in the longitudinal direction of the rail, and pressure-receiving protrusions formed between adjacent grooves,
The pressure-receiving ridges at the ends in the direction perpendicular to the rail are arranged more densely than the pressure-receiving ridges in the center, and the pressure-receiving ridges are arranged on the pad body so that they are intermittently continuous in the direction perpendicular to the rail. A groove is provided on the lower surface, and the pressure receiving protrusion on the upper surface of the pad faces the groove on the lower surface of the pad, and the groove on the upper surface of the pad faces the pressure receiving protrusion on the lower surface of the pad in the vertical direction. In addition, the width of the pressure-receiving protrusion is made smaller than the width of the concave groove vertically facing the pressure-receiving protrusion, and a concrete slab or sleeper is provided on the side end surface of the pad body in the direction perpendicular to the rail. A recessed portion that fits with a gap between a protruding shoulder provided on the seat surface of the pad device, and locking portions for the protruding shoulder at both ends facing each other in the longitudinal direction of the rail across the recessed portion. A vibration-proof track pad characterized by being provided with.
