摘要

PROBLEM TO BE SOLVED: To provide an opener of a lid for a buried chamber in the ground surface allowing a stable and easy rotating operation when the closely fitted lid is open, and preventing deformation of a rod-shaped body during the rotating operation. SOLUTION: A flat bar piece 3 is joined with a tip of the rod-shaped body 2 and a bulge 4 is provided on the upper side of the bar piece 3. A support seat 5 is provided near the lower root of the bar piece 3. The bar piece 3 is inserted into a bar hole 14 in the peripheral edge of the lid 13 supported against a lid receiving frame 12 and the bulge 4 is fitted into a recess 15 in the bar hole 14, with the support seat 5 forced to abut on the upper surface of a lid receiving frame 12.
