A lip type seal is provided with an outer ring part ( ) which is tightly fitted to a seal installation part ( ) of a housing ( ); a seal main body ( ) which is fixed to the outer ring part ( ) and whose inner circumferential part extending in a bent state to the side of a sealed space (A) is sealably brought into slidable contact with an outer circumferential surface of a rotary shaft ( ) inserted in the housing ( ); a rear surface support plate ( ) which is arranged on the rear side of the seal main body and whose outer circumferential part together with the seal main body ( ) is fixed to the outer ring part ( ); and a movable support plate ( ) which is engaged movably in a radial direction between the seal main body ( ) and the rear surface support plate ( ) and whose inner diameter is clearance fitted to the outer circumferential surface of the rotary shaft ( ). Therefore, such a gap in which the seal main body ( ) enters is not formed between the inner circumferential surface of the movable support plate ( ) and the outer circumferential surface of the rotary shaft ( ).
