5. An automatic analyzer comprising:
a container that has a lid openable and closable by a rotation fulcrum, the container accommodating a reagent or a specimen;
an analysis unit that analyzes a reaction solution aspirated from a reaction container, the reaction solution including the specimen or the reagent dispensed from the container; and
a lid closing guide, which upon relative movement of the lid closing guide with respect to the container, a side edge of the lid contacts the lid closing guide thereby closing the lid,
wherein upon closing the lid, the lid closing guide is in contact with the side edge of the lid to close the lid,
wherein, in a bottom view, a contact angle between the lid closing guide and the lid is an acute angle with respect to a rotation axis of the rotation fulcrum and a line tangential to the lid closing guide when the lid closing guide is in contact with the edge,
wherein the automatic analyzer further comprises a cover that covers the container and moves relative to the container, and
wherein the lid closing guide is provided on the cover.
