To provide a manhole cover for a passenger conveyor and a passenger conveyor which can prevent a lid body from being lifted, while at the same time preventing the lid body from being unable to be lifted.SOLUTION: A manhole cover 1 of a passenger conveyor has a lid body 2 and a locking mechanism 3 provided on the lid body 2. The locking mechanism 3 has a locking member 40 which prevents the lid body 2 from being lifted, and a transmission mechanism 30 which mechanically transmits an operating force from outside the lid body 2 to the locking member 40. The locking member 40 has a hooking part 401, and is movable between a locked position where the hooking part 401 protrudes outward from an outer periphery of the lid body 2, and a released position where the hooking part retracts inward from the lid body 2. The transmission mechanism 30 is a mechanism capable of transmitting a tensile force and a compressive force to the locking member 40.SELECTED DRAWING: Figure 3
【課題】蓋本体の浮き上がりを防止しつつ、蓋本体を持ち上げることができなくなることを抑制することができる乗客コンベアのマンホール蓋及び乗客コンベアを得ることを目的とする。【解決手段】乗客コンベアのマンホール蓋1は、蓋本体2と、蓋本体2に設けられているロック機構3とを備え、ロック機構3は、蓋本体2の浮き上がりを防止するロック部材40と、蓋本体2の外側から操作力をロック部材40に機械的に伝達する伝達機構30とを有している。ロック部材40は引っ掛かり部401を有しており、引っ掛かり部401が蓋本体2の外周から外側に突出したロック位置と蓋本体2の内側に後退した解除位置との間にて、移動可能である。伝達機構30は、ロック部材40に対して引張力及び圧縮力を伝達可能な機構である。【選択図】図3
