が設けられている。2. Description of the Related Art Generally, a passenger conveyor is constructed so that the outward side of a circulating handrail is guided along the periphery of the balustrade and the return side enters the inside of the lower part of the balustrade. A safety device is provided at the entrance of the moving handrail below the balustrade.

いる。このため、前記従来技術は、実際には乗客コンベ
アへの適用がなされていない。In the prior art described above, a part of the safety device is supported via a spring, and the spring is deformed so that the front of the safety device sinks. Once the hand or the like enters the gap between the handrail and the safety device, the spring is deformed, and the gap is further widened, so that the hand or the like easily enters. For this reason, the above-mentioned prior art is not actually applied to passenger conveyors.

することにある。The object of the present invention is to solve the above-mentioned problems of the prior art, prevent the operator from inadvertently pressing a finger or the like that has accidentally entered the gap between the entrance of the safety device and the moving handrail, and
A further object of the present invention is to provide a safety device for a passenger conveyor which can prevent further intrusion and promptly pull out a hand or the like with less malfunction.

けて構成することにより達成される。According to the present invention, the above object is to provide a protective member provided at an entrance of a circulating moving handrail, and a passenger when the protective member displaces in the traveling direction of the moving handrail. In the passenger conveyor having means for stopping the operation of the conveyor, the protective body is provided with a plurality of rod-shaped protective pieces facing the outer periphery of the moving handrail and protruding in a direction opposite to the traveling direction thereof, and This is achieved by providing a space maintaining means for maintaining the space between the plurality of protective pieces in a part of its longitudinal direction.

を防止することができる。As described above, according to the present invention, since the rod-shaped protective piece protruding forward of the protective body is provided, for example, when a finger or the like intrudes into the protective body, a gap is generated between the rod-shaped protective pieces. The protective pieces do not come apart, and the intruder such as a finger is not strongly pressed against the moving handrail.Also, the protective piece is maintained at a part of its longitudinal direction by the space maintaining means. Therefore, it is possible to prevent a problem in which the protective piece itself comes into contact with the moving handrail due to aging or is deformed to cause the detecting means to operate erroneously.
