The present invention relates to a manhole cover, in which a cover is installed to be rotationally opened and closed with respect to a cover support and is installed so that elastic force is generated in a direction of being opened by a torsion spring, thereby easily opening and closing the cover with respect to the cover support. In addition, the manhole cover mitigates impact force applied to the cover support and the cover by the vehicle so that a locking member is prevented from being damaged, thereby allowing a locking function to be maintained so that the cover is prevented from being arbitrarily opened. Therefore, collision accidents of the vehicle can be prevented. Also, the manhole cover prevents abrasion of and damage to a hinge part and the torsion spring, thereby allowing the cover to be easily opened and closed and coupling the locking member locking the cover with respect to the cover support in a one-touch manner with respect to the cover.
본 발명은 뚜껑을 뚜껑받침에 대하여 회동개폐 가능하게 설치함과 아울러 토션스프링에 의하여 개방되는 방향으로 탄성력이 발생하도록 설치함으로써 뚜껑을 뚜껑받침에 대하여 쉽게 개폐할 수 있도록 하면서도 차량에 의하여 뚜껑받침과 뚜껑에 가해진 충격력을 완화하여 잠금부재가 파손되는 것을 방지함으로써 잠금 기능을 유지하여 뚜껑이 임의로 개방되지 않도록 하여 차량의 충돌 사고를 방지할 수 있도록 하며, 힌지부와 토션스프링의 부식과 파손을 방지하여 뚜껑의 개폐가 용이하게 되도록 하고, 뚜껑받침에 대하여 뚜껑을 잠그는 잠금부재를 뚜껑에 대하여 원터치식으로 결합할 수 있도록 한 맨홀뚜껑에 관한 것이다.
