るのである。For example, the steering shaft of a car passes through the dash panel in front of the driver's seat, and at the penetration part, a sealing member is used to prevent the entry of underwater dust and noise from the engine compartment. One seat rubber l as shown in the figure is attached. That is, this seat rubber is made of an elastic material such as rubber, and is attached to the 7 langes SP attached to the dash panel 2.
and a cylindrical portion j through which the steering shaft 3 is inserted. Annular lip? , f protrude from the periphery of the opening 1 on the front and back sides, p, and KIIi2.
As shown in the figure, a sealing agent 10 such as grease is filled in the space between the pair of annular lips and the circumferential surface of the shaft 30. The presence of the sealant io ensures smooth sliding between the ll-shaped lip 9.9 and the shaft 3, and perfects the sealing effect.

Due to the lack of the *-shaped sputter, problems such as wear of the tips of the *-shaped sputters and an increase in sliding resistance occur relatively quickly.

シール部材を提供することにある。This invention was made in view of the current situation as described above.
The aim is to
- A shaft that can more reliably retain the sealant (- prevents the sealant from flowing out due to the movement of the shaft and provides a smooth and smooth seal over a long period of time). An object of the present invention is to provide a sealing member.

There is 51 sealant such as grease between this pair of annular lips and the shaft surface! In the sealing member of the shut which is laid horizontally, a sealant retaining part is formed in the shape of a circumferential groove on the inner periphery of the branching part of the above-mentioned two threads.

状に密封剤留りＩｓ／／が凹設されているものである。FIG. 8 is a book that shows only the seal part 7 of Seatrano (-) related to this armor, so this seal part 7 has an opening l through which the shaft 3 passes through, and the seal part 7 has the shape of Teno (-). A pair of annular lips 1; protrudes from the periphery of the opening to the front and back sides, respectively. A sealant retainer Is// is recessed in a groove shape.

るため、密封剤１０の麺ａｉＦｉ極めて少ない。According to the configuration in which the sealant retaining portion l/ is provided, the filling amount of the sealant io such as crease filled in the connection between the annular lip fi and the circumferential surface of the shaft 3 increases accordingly. ? ,? It becomes possible to hold a large amount of sealant IO in advance. Also, even if the shaft 3 is in the eccentric state KTo with the annular lip 'I'KN, the sealant/(N

It can be applied to various seal members.
