A tubing pump apparatus is provided. In the tubing pump apparatus, bearing members are integrally formed through engagement, whereby a first shaft of a support plate is rotatably supported by a first bearing portion of one bearing member, and a second shaft of the support plate is rotatably supported by a second bearing portion of another bearing member arranged side by side with the bearing member. By further adding a bearing member, the first shaft of the support plate provided adjacent thereto is rotatably supported by the first bearing portion of the bearing member, and the second shaft is rotatably supported by a second bearing portion of the other bearing member. In this construction, it is possible to arrange side by side a plurality of tubing pumps in the axial direction of the support plates so that it is possible to achieve a reduction in the size of the whole.
