Abstract
A grommet which is formed from a self-lubricating rubber, and can be fixed by means of a wire such as electric wires and an adhesive tape. The rubber grommet (10) is fixed to the electric wire (14) with the adhesive tapes (12, 12) and inserted into a through hole (22) penetrating through a partition (20) to provide sealing between the electric wire (14) and an inner wall of the through hole (22). Rubber forming the grommet (10) is a self-lubricating rubber containing an oily polyalkyl carbonate, which is represented by the following chemical formula: Ri—O—CO—O—[CH2CH2C(CH3)HCH2CH2—O—CO —O]n—Ri wherein n is an integer of 1 to 8, and Ri represents (i—C7H15).
Claims9
A rubber grommet fixed to a wire with an adhesive tape and providing hermetical sealing between the wire passed through a through hole penetrating through a partition and an inner wall of said through hole, in which the rubber forming the grommet is self lubricating rubber containing an oily polyalkyl carbonate lubricative component which bleeds out on a surface of the grommet to allow a reduction in frictional resistance with the inner wall of the through hole, said grommet receiving an adhesive tape that can be adhered to an oil bleeding surface of said grommet.
