Abstract
An apex seal of a rotary piston engine comprising a sealing groove formed in each apex portion of the rotor, a sealing piece and a support piece disposed in the sealing groove with a superposed relationship. A corner seal at each end of the apex seal including a corner seal member formed with a longitudinally extending slit for receiving an adjacent end of the apex seal pieces. The slit in the corner seal member is generally wider than the sealing groove of the apex seal but has a minimum width portion that is narrower than the sealing groove. The minimum width slit portion is disposed against only one of the sealing and support pieces of the apex seal so that the sideward movement of the other piece is not disturbed by the corner seal member.
