しかしながら、このような回転数検出装置の構造は、該歯付ローター（７）及 び回転数検出センサー（９）を取り付ける専用のスペースを必要とし、さらにシ ール装置（Ａ）の併設配置など複雑構造にならざるを得ないものであり、また、 その検出精度の確保からその圧入部の精密な研磨仕上げを要する。 本考案はこのような欠点に鑑み、装着スペースを削減せしめ感知性能を飛躍的 に向上せしめた車輪回転検出装置を持つシール装置を提供することを目的として いる。 However, the structure of such a rotation speed detection device requires a dedicated space for mounting the toothed rotor (7) and the rotation speed detection sensor (9), and further, a side-by-side arrangement of the seal device (A), etc. It is inevitable that the structure will be complicated and that the press-fitting part must be precisely polished to ensure its detection accuracy. In view of such drawbacks, the present invention has an object to provide a seal device having a wheel rotation detection device which has a significantly reduced mounting space and dramatically improved sensing performance.

本考案を図面に基づいて説明すると、図１に示すように、自動車のホィール軸 受部の密封をなす補強環（１）と合成ゴムまたは合成樹脂等の弾性体のシールリ ップ（２）からなったシール装置（３）であって、前記補強環（１）が交互に磁 極を有する複数個の永久磁石の配列を持つ金属で形成され、その表面を前記弾性 体またはコーティング材で被膜（４）したことを特徴としている。 The present invention will be described with reference to the drawings. As shown in FIG. 1, a reinforcing ring (1) for sealing a wheel bearing portion of an automobile and a seal lip (2) made of an elastic material such as synthetic rubber or synthetic resin are used. In this sealing device (3), the reinforcing ring (1) is formed of a metal having an array of a plurality of permanent magnets having alternating magnetic poles, and the surface thereof is coated with the elastic body or the coating material ( 4) It is characterized by doing.
【０００６】 また、補強環（１）と弾性体のシールリップ（２）からなったシール装置（３ ）であって、前記補強環（１）へ交互に磁極を有する複数個の永久磁石の配列を 持つ磁石リング（５）を配設せしめ、その表面を前記弾性体またはコーティング 材で被膜（４）したことを特徴としている。Further, a sealing device (3) comprising a reinforcing ring (1) and a seal lip (2) made of an elastic body, wherein a plurality of permanent magnets having magnetic poles alternately arranged on the reinforcing ring (1) are arranged. It is characterized in that a magnet ring (5) having the above is arranged, and the surface thereof is coated with the elastic body or the coating material (4).

本考案は、上記した構造をもって下記に示す優れた作用をなす。 すなわち、回転する軸受に固定されたシール装置（３）は図１に示すように補 強環（１）そのもの、あるいは図２に示すように該補強環（１）に密着した磁石 リング（５）が交互に磁極を有する配列となっており、回転検出センサー（図示 せず）を直接該シール装置（３）に近接設置せしめその回転を検知せしめる。従 って、極めて狭い空間にて回転検出を実施可能とする。 The present invention has the above-described structure and has the following excellent effects. That is, the seal device (3) fixed to the rotating bearing is the reinforcing ring (1) itself as shown in FIG. 1 or the magnet ring (5) closely attached to the reinforcing ring (1) as shown in FIG. Are arranged so as to have magnetic poles alternately, and a rotation detecting sensor (not shown) is directly installed close to the sealing device (3) to detect the rotation. Therefore, rotation detection can be performed in an extremely narrow space.
【０００８】 前記磁極を有する該補強環（１）あるいは磁石リング（５）の回転を感知する 回転検出センサー（図示せず）としては、交互に配置された磁石による磁気をパ ルスとして感知する磁気センサーが適当である。The rotation detecting sensor (not shown) for detecting the rotation of the reinforcing ring (1) or the magnet ring (5) having the magnetic poles is a magnet for detecting the magnetism of alternately arranged magnets as a pulse. The sensor is suitable.

本考案を実施するに、図１及び図２に示すように前記補強環（１）あるいは磁 石リング（５）を弾性体あるいはコーティング材で覆うことにより、錆、変質、 損傷等から守られるが、被膜（４）の厚みは薄膜状のものが磁力の減少を少なく しその感知能力に大きな影響を及ぼさないので好ましいものとなる。 In implementing the present invention, as shown in FIGS. 1 and 2, by covering the reinforcing ring (1) or the magnet ring (5) with an elastic material or a coating material, protection from rust, deterioration, damage, etc. can be achieved. As for the thickness of the coating film (4), a thin film-like one is preferable because it reduces the decrease in magnetic force and does not significantly affect the sensing ability.
