摘要： The invention relates to a device for immobilizing blades in the peripheral slot of a turbomachine disk. Said blades comprise roots of the hammer head type adapted to be introduced into said slot through a loading window and held in said slot by collaboration of shape with the sidewalls thereof. Said immobilizing device is adapted to be introduced into said slot through said loading window and comprises a locking element arranged in a space separating two adjacent blade roots. Said locking element is adapted to be raised up into a lock housing formed in the sidewalls of said slot under the action of a radial manipulating screw the head of which rests against the bottom of the slot, a radial clearance being provided between the bottom of the slot and the underside of the blade roots, and said screw head being restrained in a radially outward direction by said two adjacent blade roots.
