The present invention addresses the problem of providing a bearing cap for a wheel bearing device with a rotational speed detection device and a wheel bearing device with a rotational speed detection device, the bearing cap being capable of efficiently discharging foreign matter intruding into a sensor support part to the outside of the sensor support part and ensuring the rigidity of the sensor support part. In the bearing cap (11), a sensor support part (21) is formed on a bottom surface part (15c) of a cap main body (15), an insertion hole (21a) for a rotation speed sensor (19) is formed in the sensor support part (21), a recess part (15d) for accommodating a front end part of the rotation speed sensor (19) is formed in a part of the bottom surface part (15c) where the sensor support part (21) is formed, the sensor support part (21) comprises a first wall part (21b) and a second wall part (21c), and the first wall part (21b) is provided with a first opening (21c) and a second opening (21c). And a first wall section (21b) and a second wall section (21c) which are disposed so as to face each other with an imaginary line (L) passing through the axis (G1) of the bottom surface section (15c) and the axis (G2) of the insertion hole (21a) interposed therebetween, and which are formed along the peripheral edge of the recess (15d), and on the outer peripheral surface of each of the first wall section (21b) and the second wall section (21c), a protruding section (21d) protruding from the bottom surface section (15c) is continuously provided.

    本发明的课题在于提供能够将侵入到传感器支承部的内部的异物向该传感器支承部的外部效率良好地排出、且确保了传感器支承部的刚性的带转速检测装置的车轮用轴承装置用的轴承盖及带转速检测装置的车轮用轴承装置。轴承盖(11)在盖主体(15)的底面部(15c)形成有传感器支承部(21),在传感器支承部(21)形成有转速传感器(19)的插入孔(21a),其中,在底面部(15c)的形成有传感器支承部(21)的部分,形成有对转速传感器(19)的前端部进行收容的凹部(15d),传感器支承部(21)包括第一壁部(21b)及第二壁部(21c),该第一壁部(21b)及第二壁部(21c)将通过底面部(15c)的轴心(G1)和插入孔(21a)的轴心(G2)的假想线(L)夹在中间而对置配置、且沿着凹部(15d)的周缘部形成,在第一壁部(21b)及第二壁部(21c)的外周面,分别连续设置有从底面部(15c)突出的凸部(21d)。
