Mechanism for interconverting rotary motion and oscillating motion without slider comprises two parallel crankshafts (310) at the input of mechanism. The crankshaft (310) comprises two co-axial shafts (322) in-between of which is a crank (320), and the crank (320) consists of two arms (321) being connected with firmly fixed pin (323) parallel to the shaft (322). The Crankshafts (310) are coupled to the piston rod (350). The piston rod (350) comprises two levers with a groove (351) at the endings of which are firmly fixed two bearings (333) the axles of which are parallel, and in which are set pins (323) of the two cranks (320). Between the crankshafts (310) there is an outlet crankshaft (300) and its axle is parallel to the axle of crankshafts (310). The crankshaft (300) comprises two co-axial axles (302) between these there is a crank (305) which consists of two arms (301) being coupled to firmly fixed pin (303) parallel to the axle (302). The pin (303) is set inside the groove (351) of the piston rod (350). On one of both shafts (310) there are firmly fixed gear wheels (500) coupled in the engagement with the intermmediate gear (510). Length (L1) of an arm (321) of two cranks (320) at the entry is smaller than the length (L2) of the arm (301) of the crank (305) at the output which enables interconversion of rotary motion and oscillating motion with equal angular turning and equal torque at the input and output of the mechanism.
