Abstract: In a gas turbine engine, an annular intermediate-temperature space is formed by a first partition member extending from an inner platform radially inward and a second partition member having a radially inner end portion fixed to the first partition member and a radially outer end portion facing the inner platform, the inner platform being connected to radially inner ends of nozzle guide vanes of a turbine, and the intermediate-temperature space overlapping with the inner platform over substantially its axial entire length. The low-temperature space, supplied with a low-temperature air from a compressor, is formed on a radially inside of the second partition member. Therefore, a temperature of the intermediate-temperature space is maintained at an intermediate temperature between those of a combustion gas and the air, reducing a temperature difference of the inner platform from an outer platform and the vanes to reduce a thermal stress.

Abstract: In a torque transmitting mechanism of a starter, there is provided a shock absorbing arrangement having an input member and output member. When an abnormal torque appears, the members slip on each other to absorb such shock.
