Abstract
Provided is a roller pump that can easily install/remove an elastic tube and appropriately control a discharge flow rate. The roller pump includes a pump slide that is connected to a pump block cover via two slider links and restricts an arrangement of the elastic tube by an inner peripheral surface; a pump block cover that operates an opened state and a closed state of the pump slide; a first slider link that has a substantially circular contact surface in contact with the second slider link, having one end rotatably connected to the pump slide using a support pin and the other end rotatably connected to the pump block cover using a support pin; and a second slider link that has a substantially circular contact surface in contact with the first slider link and is rotatably connected to a fixed part of a base using a support pin.
