装着されこれを介して主枠１に固定されている。 In the figure, the same reference numerals as in FIGS. 1 to 5 indicate the same parts, and 6 is a guide body placed above the shaft 2c and near the footboard 3, and is fixed to the main frame 1 by a support body 6a. In addition, the shaft 2c corresponds to at least the engagement range between the drive chain 5 and the toothed link 2a, and the longitudinal axis is arranged along the moving direction of the tread chain 2.
The facing surface is made of a low-friction material such as fluororesin, and an introduction section 6b consisting of a slope is provided at the longitudinal end.
Reference numeral 6' denotes a guide body similar to the guide body 6, which is disposed below the shaft 2c opposite to the guide body 6, and is mounted on the rail 4' and fixed to the main frame 1 via the rail 4'.

る。 That is, the treadle 3 is connected to the drive chain 5 and the toothed link 2a.
When the shaft 2c moves through the engagement range of the guide body 6,
6' in a sliding state. As a result, the engagement between the drive chain 5 and the toothed link 2a causes the shaft 2 to
Even if a vertical force Fa is applied to the shaft 2c, the locus of movement of the shaft 2c is restricted to a straight line by the guide bodies 6, 6'. Therefore, unnecessary vertical movement of the treadle 3 does not occur, and a passenger conveyor with good riding comfort can be obtained.

駆動装置を実現するものである。 As explained above, the present invention is applicable to a device driven by the engagement of both a toothed link and a drive chain.
A guide body is provided to linearly restrict the locus of movement of the axis of the tread chain to which the tread plate is connected, corresponding to the range of engagement between the two, thereby preventing vertical movement of the tread plate caused by the engagement of the two. be. As a result, a driving device for a passenger conveyor with a comfortable ride that does not cause passengers to feel discomfort is realized.
