The structural complexity of conventional transfusing devices is eliminated, and it is made possible to supply a minute amount of liquid medicine with high accuracy with a simple structure, whereby a portable transfusion pump is realized. A cylindrical rotary drive member (24) equipped with a rotation shaft (23) is arranged opposite to a support plate (22), and a liquid supply tube (16) is arranged between the support plate (22) and the rotary drive member (24). On the outer peripheral surface of the rotary drive member (24), a pressing protrusion (24a) extending spirally around the axis is formed integrally. A flexible sheet (25) is provided between the rotary drive member (24) and the liquid supply tube (16). The upper and lower ends of this sheet (25) are directly or indirectly fixed to a base (10) and the support plate (22).
