<P>PROBLEM TO BE SOLVED: To provide a damper bearing device which eliminates a squeeze effect by oil within slit, in which oil leakage from slit side section is prevented without constantly supplying oil to the inside of the slit from the outside, the squeeze effect is prevented from reducing by the oil leakage and vibration damping action is prevented from reducing, a normal vibration damping action can be always performed, and the damper bearing device is made simple and lightweight. <P>SOLUTION: A ball bearing supported in an inner circumferential side of damper bearing body 2 is constructed by a bearing structure of self-lubricating type and includes seal members 5, 5 which are arranged in a circumferential direction along slits 6a, 6b so that the end surface of the damper bearing body 2 of the slits 6a, 6b of fine width may be covered and consist of elastic boy, and seal pressers 7a, 7b which fix the seal members to the damper bearing body 2. <P>COPYRIGHT: (C)2011,JPO&INPIT |
