1. An eccentric sliding assembly in accordance with the present invention comprising:
a first sliding component formed in an annular shape and having a sliding surface, wherein
a second sliding component having a sliding surface; and
an eccentric driving device configured to cause the sliding surface of the first slide component to slide relative to the sliding surface of the second sliding surface such that a center of the first sliding component imaginarily draws a circle which is eccentric with respect to a center of the second sliding component while keeping non-rotation state of the first sliding component with respect to the center of the first sliding component in a plan view,
the sliding surface of at least one of the first sliding component and the second sliding component is provided with a plurality of grooves each of which is open to a fluid space on at least one of an inner diameter side and an outer diameter side and which are arranged in a circumferential direction, and
a side wall surface of each of the grooves is configured by a wall surface continuous in a circular arc shape in a plan view.
