も容易になり、つまずきは低減される。According to the above construction, since there is no convex portion at the tip of the comb plate which meshes with the tread cleats, with respect to the toes of passengers and passengers moving from the tread to the boarding / alighting floor, the vehicle has a relatively small force. However, it is possible to ride on the tip of the comb plate, and once riding, it can move to the boarding / alighting side as it is due to its inertia. Similarly, the passenger's toes can easily get on the comb plate, and tripping can be reduced.

る。In the above structure, when it is attempted to move the carrier from the tread plate 5 to the boarding / alighting side, conventionally, as shown in FIG. 1 (b), the surface of the comb portion 21 'is convex as shown by a chain double-dashed line. Because it is in a shape, its inclination is large. Therefore, if the front wheel 28 'of the carrier collides with the comb 21',
Since the inclination is large, the collision occurs from the top of the cleat 5C of the tread 5 at a high position P ', so that a considerable force and reaction force are generated to ride the front wheel 28'. However, according to the present embodiment, since the inclined surface 24 is a gently inclined flat surface, the position P at which the front wheel 28 of the carrier collides with the comb portion 21 is
It is in a low position close to the top of the cleat 5C of the tread 5. Therefore, the front wheel 28 can be ridden on the comb plate 14 with a small reaction force only by pushing the carrier with a small force.

故をなくすことができる。Further, the fact that the inclined surface 24 is a flat surface having a gentle inclination can prevent the occurrence of a fall accident even for passengers. That is, if the passenger reaches the boarding / alighting floor 7 without raising his / her foot, the passenger can ride on the gentle slope 24 at the tip of the comb plate by inertia, and therefore, the passenger will not fall down without riding. On the other hand, although it is dangerous to slide on the comb plate 14 forever due to inertia, there is an inclined surface 25 that is steeper than the inclined surface 24 in the traveling direction of the inclined surface 24. To be prevented. Therefore, the tripping of the comb plate 14 when the passenger moves to the floor 7 is eliminated, and a fall accident due to the tripping of the comb plate 14 can be eliminated.
【００１７】尚、緩い傾斜面２４に連続させて急傾斜の

ての機械的強度を確保することができる。The purpose of forming the steeply inclined surface 25 continuously with the gentle inclined surface 24 is as follows. That is,
As shown in FIG. 1B, when the inclined surface 24 is originally extended to the side of the base 20 as shown by the chain double-dashed line, the plate thickness t ′ of the base 20 facing above the comb plate mounting portion 16 is thin. When the load is applied to the comb portion 21, the strength cannot be ensured and there is a risk of breaking. Therefore, by providing the inclined surface 25 on the extension of the inclined surface 24, the reduction of the plate thickness t of the base portion 20 is prevented as much as possible and the reduction of the strength is eliminated. In addition, the mounting surface 15 of the comb plate mounting portion 16
Is inclined at an inclination angle θ2, and the top surface of the base portion 20 of the comb plate 14 is inclined at an inclination angle θ5 that is gentler than the inclination angle θ2. Therefore, the base portion 20 of the comb plate 14 follows the tip. The plate thickness t becomes thick, and the mechanical strength from the base portion 20 to the tooth portion 21 can be secured.

を奏することができる。Further, the plate thickness t of the base portion 20 of the comb plate 14 can be secured without providing the inclined surface 25. The structure is such that the top end of the comb teeth 22 to the base portion 20 having a plate thickness t.
The flat inclined surface 24 is formed to reach the end. In this configuration, since the inclined surface 25 is not provided, the inclination angle of the inclined surface 24 becomes steeper than that in the above-described embodiment. However, as compared with the convex curved surface of the conventional comb portion 21 'shown by the chain double-dashed line in FIG. 1 (b), the inclination angle θ is shown in the drawing.
Since it is close to 3, the same effect as that of the comb plate according to the above-described embodiment can be obtained.

与できる。In addition, since the illuminating light near the entrance / exit is dispersed at different angles by making the inclined surfaces 24 and 25 adjacent to each other, the presence of the boundary portion between the getting on / off floor and the tread, which often causes a fall accident, is given to the passenger. It can be recognized and can contribute to the improvement of safety.

In particular, it is intended to prevent the soft sole from being caught, and has a great safety effect as a whole structure of the comb plate 14.

転倒を回避できることを意味する。(2) As can be seen from Table 2 regarding the riding distance to the comb plate, when the rider rides forward regardless of the inclination angle of the comb plate, the shoes are riding on the comb plate. Looking at the distance, the product of the present invention having a small inclination angle is long, and the time until the product stops is also long for the product of the present invention. However, in the case of riding backward, the product of the present invention, which has a small comb plate inclination angle, is long in the riding distance and the time until stopping. As a result, the product of the present invention has a small impact force of the shoe on the comb plate,
This means that you can avoid falls.
