A rocking mechanism ( 12 ) through which linear reciprocating movement of a piston ( 14 ) of an internal combustion engine ( 10 ) can be transferred, from the remote end of a connecting rod ( 22 ) on which the piston is mounted, to a crankshaft ( 20 ). The mechanism includes: a rocking member ( 28 ); Mountings ( 40 ) by which the rocking member is mountable in relation to the crankcase ( 18 ) for the engine, for reversible rocking movement on a first axis (X 1 ); A link member ( 30 ) pivotally connected at one end, to the rocking member so as to be pivotable relative to the rocking member on a second axis (X 2 ) between two extreme positions; and Holding means (32
