Device for axially supporting the strut of a stator ring of the high-pressure turbine of a turbomachine

The device includes a longitudinally-extending sheet metal piece (46) constituting a heat shield arranged upstream from the upstream radial wall (18) of a spacer sector (16) against the inner surface of a casing (14). The sheet metal piece bears axially against the upstream radial wall of spacer sector and is secured to the casing to hold the spacer sector axially.
