[Claims for Utility Model Registration] (1) A lock having a structure in which a hook member 4 that engages with an inner protruding edge 3 of a frame 2 that receives a cover 1 of an underground structure is pivotally supported on the periphery of the back surface of the cover. The mechanism has a contact surface 5 on the outside near the pivot point of the hook member 4, and the lid opening arm 6 is pivotally supported on the back surface of the lid so that its tip faces the small opening 1a of the lid 1. A pressing portion 7 is provided in the vicinity of the tip portion to abut against the abutment surface 5 and push the hook member 4 in a direction away from the inner protrusion 3, and a member 8 for regulating the hook member 4 to the locked position when the lid is closed is provided. A locking mechanism for an underground structure characterized by being provided at the other end of a lid arm 6. (2) The hook member 4 has a bifurcated shape with a hollow space 10 between the support shafts 9, 9 through which the tip of the lid opening arm 6 passes, and has two contact surfaces 5 on the outside thereof. A locking mechanism for underground structures according to registered claim 1. (3) The locking mechanism for an underground structure according to claim 1, wherein the regulating member 8 is a weight that pushes the hook member 4 from the back in the locking direction.
