従来、自動車のスキッドを防止するためのアンチスキッド用回転数検出装置と しては次のような構造が多く用いられている。 すなわち、前記回転検出装置は歯付ローターと感知センサーからなっており、 その際軸受を密封するシール装置よりそれぞれ離間させて配置し、一つの独立し た回転数検出装置を構成しているものが一般的である。 以下、図面を参照しつつ詳述する。 Conventionally, the following structure is often used as an anti-skid rotation speed detection device for preventing skid of an automobile. That is, the rotation detecting device is composed of a toothed rotor and a sensor, and at that time, the rotation detecting device is arranged separately from the seal device for sealing the bearing, and constitutes one independent rotation speed detecting device. It is common. Hereinafter, a detailed description will be given with reference to the drawings.
【０００３】 このような従来例を示すと、図４のように回転軸（５）に嵌合された金属製の 焼結体か板金加工体からなる歯付ローター（６）を、ナックル（７）に取付られ た回転検出センサー（８）で感知検出する構造を示している。 ここで軸受（９）はその側部に独立して設けられたシール装置（Ａ）によって 水分あるいは異物の侵入から守られている。To show such a conventional example, as shown in FIG. 4, a toothed rotor (6) made of a metal sintered body or a sheet metal processed body fitted to a rotating shaft (5) is attached to a knuckle (7 The structure for detecting and detecting by the rotation detection sensor (8) attached to () is shown. Here, the bearing (9) is protected from intrusion of moisture or foreign matter by a seal device (A) provided independently on its side.

しかしながら、このような回転検出装置の構造は、該歯付ローター（６）及び 回転検出センサー（８）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、歯付 ローター（６）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 に向上させた車輪回転検出のための回転検出装置を有したベアリングシールを提 供することを目的としている。 However, the structure of such a rotation detecting device requires a dedicated space for mounting the toothed rotor (6) and the rotation detecting sensor (8), and has a complicated structure such as a side-by-side arrangement of the seal device (A). In addition, the press fit portion of the toothed rotor (6) needs to be precisely polished. In view of such drawbacks, the present invention aims to provide a bearing seal having a rotation detection device for wheel rotation detection, which has a significantly reduced sensing space and dramatically improved sensing performance.
