摘要： A lid for an underground structure is constituted of a lid body (10) and a reception frame (20). An inclined surface (11) on an outer periphery of the lid body is fitted in and supported by an inclination surface (21) of an inner periphery of the reception frame. The inclination surfaces (11, 21) of the lid body outer periphery and the reception frame inner periphery have upper inclination surfaces (11a, 21a) and lower inclination surfaces (11b, 21b), respectively. The inclination of the lower inclination surfaces (11b, 21b) is made sharper than that of the upper inclination surfaces (11a, 21a). The lid body (10) is fitted in and supported by the reception frame (20) at the upper inclination surfaces (11a, 21a) and the lower inclination surfaces (11b, 21b), and this prevents the lid body from excessively biting into the reception frame and also prevents the lid body from obliquely biting into the reception frame or from being obliquely placed in the reception frame.
