Claims

[Scope of utility model registration request]

A first protrusion having a wavy longitudinal section, and a second protrusion having a waveform longitudinal section having the same wavelength and shorter amplitude as the first protrusion.
Protruding stripes are integrally formed on the surface of a sheet-like base made of an elastic body alternately in the same direction with a phase shift of 1/2 of a wavelength, and the width of the cross section of the second protruding strip is equal to the width of the cross section of the first protruding strip. A third protrusion that is formed wider than the width of the surface and has a wavy longitudinal section, and a fourth protrusion that has a waveform longitudinal section that has a wavelength equal to that of the third protrusion and has a shorter amplitude,
They are integrally formed alternately in the same direction with a phase shift of 1/2 of a wavelength on the opposite surface of the base, and the width of the cross section of the fourth protrusion is made wider than the width of the cross section of the third protrusion. , wherein the protrusion of the first protrusion and the recess of the fourth protrusion are opposed to each other, and the protrusion of the second protrusion and the recess of the third protrusion are opposed to each other. Shake it.
