PROBLEM TO BE SOLVED: To provide a seal washer 10 inseparable from a washer body 11 even when a seal lip 12 is subjected to compressive deformation. SOLUTION: The seal washer 10 comprises the seal lip 12 of a rubber elastic material integrally formed on the inner periphery of the washer body 11. Recessed portions 111a, 111b are formed on both sides of an inner peripheral portion 111 of the washer body 11 in the axial direction. A plurality of through-holes 113 communicating the recessed portions 111a, 111b with each other are opened at preset spaces in the circumferential direction. Parts 121-123 of the rubber elastic material for the seal lip 12 are filled in the recessed portions 111a, 111b and the through-holes 113. COPYRIGHT: (C)2005,JPO&NCIPI
