PCT No. PCT/FR87/00509 Sec. 371 Date Aug. 23, 1988 Sec. 102(e) Date Aug. 23, 1988 PCT Filed Dec. 22, 1987 PCT Pub. No. WO88/04599 PCT Pub. Date Jun. 30, 1988.The present invention relates to an apparatus for translatory manipulation of an element, such as an axle. Apparatus characterized in that it comprises a displacement device (2) for each direction in space in which the axle (1) is to be manipulated, each displacement device (2) comprising two blades (3) prestressed in opposition, constituted by an alloy which is pseudoelastic or has shape memory, disposed on opposite sides of heating and/or cooling means (4) giving rise to a thermal gradient between the two blades (3) and thus their martensitic transformation causing their deformation.
