Pushing structure and relay

The utility model relates to the technical field of electronic control devices, in particular to a pushing structure and a relay. The pushing structure comprises a pushing rod, the pushing rod is provided with a first end and a second end, and an annular groove is formed in the circumferential surface of the pushing rod and used for installing a check ring; in the axial direction of the push rod, the vertical distances between the groove bottom of the annular groove and the axis of the push rod are not completely equal; the check ring can abut against the set position of the groove bottom of the annular groove, and a gap is formed between the set position and the groove wall, close to the second end, of the annular groove. When the check ring abuts against the set position of the groove bottom, the distance between the surface, close to the first end, of the check ring and the groove wall, close to the first end, of the annular groove is small, the inclination degree of the check ring can be reduced as much a
