<p>Disclosed is a material pumping apparatus (10) provided with: a container (12) that contains a bag (11) containing a cohesive material (M); a pressing member (13) that applies a pressing force to the material; a pumping means (15) that pumps the material (M), which is suctioned by the pressing force of the pressing member (13), to the outside; and an annular member (16) that is located at the outer periphery of the pressing member (13). A support space (S) is provided on the outer of the pressing member (13), and a ring section (40) constituting the annular member (16) is supported by the support space (S) in a relatively moveable state. As a result of this configuration, even if the pressing member (13) is inclined, the annular member (16) will not be affected by the incline, and a gap will not occur on the inner peripheral surface of the container (12).</p> |
