Abstract

Provided is a drip-proof device for a passenger conveyer, which is capable of improving working efficiency of maintenance work performed in a machine room. The drip-proof device for a passenger conveyor includes gutters, which are provided to a floor plate for opening and closing an opening portion of a machine room, and are each configured to receive water passing through a gap between wall surfaces of the opening portion and the floor plate, and a gutter displacement device configured to displace the gutters. Each of the gutters is displaced between a water-receiving position for receiving the water passing through the gap and a receiving position for allowing removal of the floor plate through the opening portion. The gutter displacement device includes a rotary member configured to rotate through an operation of the rotary member- and rods configured to displace the gutters through the rotation of the rotary member.

Claims (10)

1. A drip-proof device for a passenger conveyor, comprising:

a gutter, which is provided to a floor plate for opening and closing an opening portion of a machine room, and is configured to receive water passing through a gap between a wall surface of the opening portion and the floor plate,

wherein the gutter is displaced between a water-receiving position for receiving the water passing through the gap and a receiving position for allowing removal of the floor plate through the opening portion.
