このものは、ブレーキドラム１のドラム摺動部
２の外周面に弾性材３を弾圧させて、保持リング
４で保持させ、これによりブレーキドラムの固有
振動数を低下させ、振動の防止を図つていた。 In this device, an elastic material 3 is pressed against the outer circumferential surface of a drum sliding portion 2 of a brake drum 1 and held by a retaining ring 4, thereby lowering the natural frequency of the brake drum and preventing vibration. was.
しかし、この構造のものはブレーキドラム１の
回転による遠心力により弾性体３がずれ落ちる欠
点があり、しかも別部材である保持リング４を必
要とするなどの欠点があつた。 However, this structure has the drawback that the elastic body 3 slips off due to the centrifugal force caused by the rotation of the brake drum 1, and furthermore, a retaining ring 4, which is a separate member, is required.
「考案の目的」
この考案は、部品点数が少なく、極めて簡単且
つ迅速に取付けることができ、しかも弾性体が離
脱することのないブレーキドラムの防振装置の提
供を目的とする。``Purpose of the invention'' The object of this invention is to provide a brake drum vibration isolator that has a small number of parts, can be installed extremely easily and quickly, and does not cause the elastic body to come off.

の防振装置である。``Structure of the invention'' The gist of this invention is to interpose elastic materials at multiple locations on a concentric circle between the vertical wall of the brake drum and the disc wheel, and to fasten the disc wheel to the brake drum with a tightening member. This is a brake drum vibration isolating device in which an elastic material is clamped and clamped between the disc wheel and the vertical wall of the brake drum.

ることもない。``Effect of the invention'' According to this invention, a plurality of elastic materials are interposed between the vertical wall of the brake drum and the disc wheel, and the elastic materials are tightened and compressed, and are held between the vertical wall of the brake drum and the disc wheel. Therefore, it is possible to reliably lower the natural frequency of the brake drum and suppress vibration with a small number of components. In addition, it can be installed extremely easily and quickly, the elastic material is firmly held, and the rotation radius of this elastic material is smaller than when it is provided on the outer peripheral surface of the drum sliding part of the brake drum. Therefore, the centrifugal force is small and this elastic material will not come off.
「実施例」
この考案の一実施例を、以下図面に基づいて詳
述する。"Embodiment" An embodiment of this invention will be described below in detail based on the drawings.
尚以下の実施例は本考案の具体的一例にすぎ

５の回転半径が小さいのでその遠心力が小さく、
弾性材１５が離脱することがなく、さらに部品点
数を少なくすることができる。 As shown in the figures and the embodiment, a plurality of elastic members 15 are interposed between the vertical wall portion 17 of the brake drum 16 and the disc wheel 11, and are tightened and compressed, and are held between the vertical wall portion 17 and the disc wheel 11. Therefore, the natural frequency of the brake drum 16 decreases. In addition, the installation can be done extremely simply, quickly, and firmly, and the elastic material 1 according to the structure of this embodiment can be installed more easily than when the elastic material 15 is provided on the outer peripheral surface of the drum sliding portion of the brake drum 16.
Since the rotation radius of 5 is small, the centrifugal force is small,
The elastic material 15 does not come off, and the number of parts can be further reduced.
