Abstract

PURPOSE: To provide a manhole lid, which comprises a sliding door(s) capable of being housed into a housing portion arranged to a holding frame, so that the working space around the manhole will not be narrowed and the sliding door can be lightly handled.
CONSTITUTION: The present manhole lid comprises a rectangular holding frame 1 having at one side thereof a housing portion 3 with an opening through which a sliding door 2 of plate can be withdrawn into the housing portion 3. Locking of the sliding door 2 can be effected when one end of the sliding door 2 is secured to the portion of the holding frame 1 which can overlap the end or when an anchor piece 5 rotatably attached to the underside of the sliding door 2 is anchored to an anchor edge 7 on the underside of the holding frame 1. Therefore when the sliding door is opened it is neatly arranged and the working space around the manhole will not be narrowed. The sliding door can adopt the locking mechanism so that the sliding door cannot be accidentally opened by mischief of a child though it is lightly handled when necessary.
