Substrate container and its door assembly, support assembly, and elastic buffer element

A support assembly of a substrate container, comprising:

• a supporter, disposed on one side of the storage space of the substrate container, the supporter having at least one protrusion, the protrusion facing an inner wall surface of the substrate container;
• and
• at least one elastic buffer element, disposed at the protrusion, the elastic buffer element comprising a sleeve, the sleeve having two sleeve abutting surfaces, the two sleeve abutting surfaces connected to form a sleeve space and a sleeve opening in communication with the sleeve space, wherein the protrusion is placed into the sleeve space from the sleeve opening, and the two sleeve abutting surfaces are used for tightly abutting between the supporter and the inner wall surface.

An elastic buffer element, used in a substrate container, the substrate container provided with a first part and a second part, the first part having a protrusion;

• the elastic buffer element comprising:
• a sleeve, sleeved at the protrusion and for tightly abutting between the first part and the second part.
