[Problems to be solved by the device]

従来の技術で述べたものにおいて、Ｖ型レールと金属戸車とのものより転動による騒音及び振動は少しは軽減されるが、著しく防振と防音を必要とする戸車の場合には、硬質合成樹脂の車輪では、不適当であると云う問題点がある。本考案は、上記従来の欠点を改良したものであつて、その主たる目的とする所は、従来のＶ型レールにおける防音戸車の諸問題を解決するものであつて、Ｖ型レールに対応する戸車の内輪部の外周に設けたＶ凹溝部に弾性環体を嵌装して、防音効果と緩衝効果を確実に実施すると共に、該弾性環体を強固に保持するＶ型レール用防音戸車を提供するものである。 Although the noise and vibration due to rolling can be reduced a little as compared with those of the V-shaped rail and the metal door roller in the one described in the prior art, in the case of the door roller that requires significant vibration and sound insulation, Synthetic resin wheels have the problem of being unsuitable. The present invention is an improvement on the above-mentioned conventional drawbacks, and its main purpose is to solve various problems of the soundproof door wheel in the conventional V-type rail, and to cope with the V-type rail. Provided is a V-type soundproof door roller for rails, in which an elastic ring body is fitted into a V-shaped groove provided on the outer periphery of the inner ring part to surely perform a soundproofing effect and a cushioning effect, and which firmly holds the elastic ring body. To do.

[Means for Solving the Problems]

上記目的を達成するために、本考案のＶ型レール用の防音戸車は、戸車本体の車輪を硬質合成樹脂製の内輪部と、その外周に軟質弾性体の弾性環体を以て一体成形される。この内輪部には、外周全体にＶ凹溝部を形成すると共に、このＶ凹溝部の両側に支持側片を各々突設して形成する。また、該Ｖ凹溝部の内部にＶ型の該弾性環体を一体的に形成すると共に、該弾性環体の外周を該Ｖ凹溝部より突設した形成となつている。従つて、本考案によると、騒音の激しい金属製のＶ型レールに使用すると、騒音を確実に防止する効果と、弾性環体が押圧されて外部に押し出されて破損する等の憂いがない効果がある。 In order to achieve the above object, a soundproof door roller for a V-shaped rail according to the present invention is formed by integrally forming a wheel of a door roller main body with an inner ring portion made of hard synthetic resin and an elastic ring body of a soft elastic body on the outer periphery thereof. In this inner ring portion, a V-shaped groove portion is formed on the entire outer circumference, and supporting side pieces are formed on both sides of the V-shaped groove portion so as to project. Further, the V-shaped elastic ring body is integrally formed inside the V concave groove portion, and the outer periphery of the elastic ring body is formed to project from the V concave groove portion. Therefore, according to the present invention, when it is used for a noisy metal V-shaped rail, it has the effect of reliably preventing noise, and there is no fear of the elastic ring body being pressed and pushed out to the outside to be damaged. effective.
