An extrusion device, for tubes, includes: an accommodation member having pushing holes formed through both sides facing each other and a discharge hole formed in the upper end thereof and connected to an internal space thereof; and a pressing member installed inside the internal space and having a pair of pressing bodies arranged symmetrically with each other, each including a compression portion provided on the opposite side of a pushing portion exposed through each pushing hole to discharge contents in the deformable tube accommodated between the compression portions through the discharge hole by pressing of the pushing portions, wherein a plurality of fine adjustment pieces that protrude from the compression surfaces of the compression portions may vary in the degree of elastic deformation according to the pressing force of the pushing portions, thus adjusting the surface of contact with the tube and adjusting the discharge amount of the tube contents.
