<P>PROBLEM TO BE SOLVED: To provide a sealing structure and a bearing device that are convenient for use in the case that a lid member is easy to be attached and detached and in which the lid member hardly falls off even after a long time use. <P>SOLUTION: Two grooves are formed at the outer end with respect to the axial direction of the inner circumference surface of an oil shield 4 that is stationary relative to the axle with an interval therebetween along the circumferential direction. The lid member 50 has an annular portion 70 and a sealing portion 71 for sealing one opening that opens in the axial direction of the annular portion 70. The annular portion 70 has two projections 72 formed with an interval therebetween along the circumferential direction. The lid member 50 is engaged with and fixed to the oil shield 4 by fitting the projections 72 of the lid member 50 to the grooves 62 of the oil shield 4 and making them engaged with each other. <P>COPYRIGHT: (C)2010,JPO&INPIT |
