A nip roller direction conversion device of a contraction film maker is provided to reduce the failure rate by simply manufacturing the device and by keeping the film thickness uniform. A nip roller direction conversion device of a contraction film maker comprises: an extruder fusing the synthetic resin material to extrude; an elongation unit drawing a tube(4) not extended in order to have the necessary shrinkage ratio; a transfer winding unit transferring the extended tube and reeling; a nip roller installed between the extruder and the transfer winding unit to change a transfer path of the tube; and a nip roller direction changing unit(60). The nip roller direction changing unit includes: a frame(61) fixing all kinds of tools; a rotation latency(63) freely rotating within the flame inside with a bearing(64); a rotatable actuating motor(66) compulsorily running a small gear(65) going in gear between a toothed gear of the rotation latency; a fixed nip roller(67) fixed to the rotation latency; a variable nip roller(68) location-controlled by the advance and reverse of a cylinder(71); and a nip roller driving motor transferring of a tube.
