An apparatus for converting linear motion into rotary motion or vice versa comprising a shaft ( 12 ) which is rotatable about a fixed axis ( 14 ) and carrying a circular cam ( 16 ) mounted eccentrically relative to that axis ( 14 ), the cam ( 16 ) being rotatably mounted within a disc ( 22 ) which is in turn rotatably mounted within a housing ( 24 ) mounted for linear reciprocating motion along a rectilinear axis ( 26 ) in a direction transverse to the axis ( 14 ) of the shaft ( 12 ) whereby reciprocating motion of the housing ( 24 ) along the rectilinear axis ( 26 ) is converted into rotation of the shaft ( 12 ), or rotation of the shaft ( 12 ) is converted into reciprocating motion of the housing ( 24 ) along the rectilinear axis ( 26 ).
