Abstract
A resin lip type seal has first and second inner peripheral seal lips and an outer peripheral seal lip slidably contacting an operation member and a fixed member. The second inner peripheral seal lip is formed in a plate-shape to extend obliquely in an inner peripheral direction toward a second sealed fluid side so that an inner peripheral side end portion slidably contacts with a shaft and an outer peripheral side end portion contacts with a tapered surface formed on a housing or an installation member of the housing, whereby contact surface pressure in the inner peripheral direction acts on the inner peripheral side end portion.
