A transmission mechanism (1) comprises a rotating shaft (2) having an axis of rotation (3), a reciprocating member (4), which is displaceable with respect to the axis of rotation (3), a ring (9) which is rotatably mounted to the rotating shaft (2) and rotatable about a ring axis (11) extending parallel to the axis of rotation (3), a first rod (22) which is pivotally coupled to the reciprocating member (4) at a first reciprocating member pivot axis (28) and to the ring (9) at a first ring pivot axis (18), and a second rod (23) which is pivotally coupled to the reciprocating member (4) at a second reciprocating member pivot axis (29) and to the ring (9) at a second ring pivot axis (19). A circular member (7) is attached to the rotating shaft (2) and located eccentrically with respect to the axis of rotation (3). The ring (9) is rotatably mounted about the circular member (7) such that the centre line of the circular member (7) coincides with the ring axis (11), and wherein the outer circumference of the circular member (7) extends beyond the outer circumference of the rotating shaft (2) in at least one direction of the axis of rotation (3). |
