A OPENS THE DOOR WHICH USES AN ELASTIC SUPPORT SYSTEM AND THE SYSTEM WHICH CLOSES

摘要

An elastic support and a door opening/closing apparatus using the same are provided to absorb an impact occurring at an oil injection port when the oil injection port is closed. A door opening/closing apparatus comprises a protrusion(210) having a coupling member(212) and an elastic support(200) fixed to the protrusion. The protrusion has a space therein. The protrusion is provided at an inner portion of an oil injection port(100) and one side of the protrusion is open. The elastic support supports the oil injection port such that the oil injection port is automatically open. The elastic support is provided in opposition to a hinge bracket. A coupling slot(222) is formed at an outer circumferential portion of the elastic support and a guide hole(224) is formed in the elastic support.
