A pair of left and right drive sprockets 13 and 13 are fixed to both ends of the rotating shaft 32, and a power sprocket 41 is fixed to one drive sprocket 13 (the right sprocket in FIG. 2) with a bolt or the like. The pair of left and right drive sprockets 13 and 13 and the power sprocket 41 rotate integrally with the rotary shaft 32. A power transmission chain 42 is stretched between the power sprocket 41 and the drive device 14.

  The driving device 14 is driven and controlled by a control device (not shown) that controls the entire passenger conveyor 1, so that the driving force generated by the driving device 14 is passed between the power sprocket 41 and the driving device 14. Is transmitted to the rotary shaft 32 through the power transmission chain 42, and the rotary shaft 32 and the pair of left and right drive sprockets 13 and 13 rotate integrally. As the driving sprockets 13 and 13 rotate, the driving force is transmitted to the step chain 12 meshing with the driving sprockets 13 and 13, so that the plurality of steps 3 connected by the step chain 12 are connected to the front wheel side guide rail 9 and While being guided by the rear wheel side guide rail 10, it is structured to circulate between the entrance / exit on the upper floor side and the entrance / exit on the lower floor side.

  As shown in FIG. 2, the skirt portion 5 is disposed opposite to the widthwise end portion 3 a of the step 3 and protects the user's feet, and is fixed to the upper end portion of the skirt guard panel 20 and secured to the balustrade. The inner deck 22 arranged on the side of the panel 4 close to the step 3 (ie, the inside of the balustrade panel 4) and the position away from the step 3 of the balustrade panel 4 (ie, the outside of the balustrade panel 4) And an outer deck 23 sandwiching the balustrade panel 4 with the deck 22.

  In the present embodiment, the inner deck 22 and the outer deck 23 disposed on the balustrade panels 4 and 4 have the same shape on the left and right.

  The handrail belt 6 synchronizes the peripheral portion of the balustrade panel 4 with the step 3 by a handrail belt driving device 35 disposed inside the skirt portion 5 defined by the skirt guard panel 20, the inner deck 22 and the outer deck 23. Cycle around.

  That is, at the time of driving in the upward direction in which the step 3 moves from the lower floor side to the upper floor side, the handrail belt 6 on the road side from the inside of the skirt portion 5 appears on the entrance side of the lower floor and appears on the outside, and the entrance of the upper floor The handrail belt 6 on the return side passes through the inside of the skirt portion 5 and moves to the entrance / exit side of the lower floor. In addition, during the downward movement in which the step 3 moves from the upper floor side to the lower floor side, the handrail belt 6 on the side of the road from the inside of the skirt portion 5 appears outside at the entrance / exit side of the upper floor, and the lower floor floor The handrail belt 6 enters the skirt portion 5 on the mouth side and moves to the entrance / exit side of the upper floor through the inside of the skirt portion 5.

  The handrail belt 6 on the road side slides on the guide rail 16 disposed on the upper end portion of the balustrade panel 4 via the handrail deck 15, and thus travels on the upper end side of the balustrade panel 4 so that the user's hand. Used to grab with.

  The handrail belt 6 on the return path side is sandwiched between a driving roller 36 and a narrow pressure roller 37 that are paired up and down with the handrail belt driving device 35. Power from the drive device 14 is transmitted to the drive roller 36 via a handrail sprocket 38 fixed to the rotating shaft 32 of the drive sprocket 13 and a chain 39 wound around the handrail sprocket 38. As a result, the handrail belt 6 sandwiched between the drive roller 36 and the narrow pressure roller 37 runs endlessly in synchronization with the step 3.

  In the passenger conveyor 1 of the present embodiment as described above, as shown in FIG. 2, the length along the step width direction W from the handrail belt 6 to the side frame 2a of the adjacent truss structure 2 is different on the left and right. Yes. Specifically, the step width direction W from one handrail belt (for example, the right handrail belt in FIG. 2) 6a to one side frame (for example, the right side frame in FIG. 2) 2a of the truss structure 2 is described. Is a step width direction from the other handrail belt (for example, the left handrail belt in FIG. 2) 6b to the other side frame (for example, the left side frame in FIG. 2) 2a of the truss structure 2 The truss structure 2 and the handrail belt 6 are disposed so as to be larger than the distance b of W.

  In other words, the center position P1 of the distance between the left and right side frames 2a corresponding to the center position of the truss structure 2 in the step width direction W is different from the center position P2 of the distance between the left and right handrail belts 6a, 6b. Left and right handrail belts 6 a and 6 b are arranged asymmetrically with respect to the structure 2.

  Further, the step 3 is disposed in the truss structure 2 so that the center position P3 of the step 3 in the step width direction W coincides with the center position P2 of the distance between the left and right handrail belts 6a, 6b, and the step. The left and right front wheels 7 and 7 are arranged on the step 3 so that the center position P4 of the interval between the left and right front wheels 7 and 7 attached to 3 coincides with the center position P2 and the center position P3 described above.

  As described above, in the passenger conveyor 1 of the present embodiment, the width of the truss structure 2 is varied by changing the length along the step width direction W from the handrail belt 6 to the side frame 2a of the truss structure 2 on the left and right. While the space for disposing the power sprocket 41 on one side in the direction can be secured, an unnecessary space on the other side can be set small, so that the width dimension of the truss structure 2 can be reduced. Installation space can be reduced.

  Moreover, in the passenger conveyor 1 of this embodiment, the truss installed in the building so that the center position P3 of the step 3 in the step width direction W coincides with the center position P2 of the interval between the left and right handrail belts 6a and 6b. Handrail belts 6 a and 6 b and steps 3 are arranged with respect to the structure 2. Therefore, even if the left and right handrail belts 6a and 6b are arranged asymmetrically with respect to the truss structure 2, the left and right handrail belts 6a and 6b can be arranged symmetrically with respect to the step 3. The passenger conveyor 1 can be used without the user feeling uncomfortable.

  In addition, in the present embodiment, the left and right outer decks 23, 23 disposed on the balustrade panels 4, 4 have the same shape, so that the left and right handrail belts 6 a, 6 b are asymmetric with respect to the truss structure 2.
