  As shown in FIG. 2, the step 2 includes a tread plate 2a on which the passenger rides, and a number of cleat grooves 2b are formed on the surface of the tread plate 2a.

  As shown in FIG. 3, tips 4a (shown in FIG. 7) of comb teeth 4 attached to the floor board of the entrance / exit are engaged with the cleat groove 2b of the tread board 2a. This prevents passengers from being pulled in when getting on and off the entrance and exit, thereby ensuring the safety of the passengers.

  As shown in FIG. 4, the step 2 according to the present embodiment sets the cleat groove 2b of the tread 2a to a shape in which the upper end 2f is wider than the vicinity of the bottom 2e, and the cleat groove 2b is located near the bottom 2e. It has a space part into which the tip 4a of the comb tooth 4 can be inserted.

  Further, the cleat groove 2b has a restricting portion, for example, a step portion 2g, that restricts foreign matter that has entered the cleat groove 2b from falling in the direction of the bottom 2e of the cleat groove 2b.

  The cleat groove 2b has a first space portion 2c above the step portion 2g, and forms a space portion into which the tip 4a of the comb tooth 4 described above can be inserted below the step portion 2g. Two space portions 2d are provided.

  Furthermore, the entire cleat groove 2b is set to have a shape that gradually widens from the bottom 2e side to the upper end 2f side. That is, in the second space 2d, the shape gradually increases from the bottom 2e side toward the step 2g, and in the first space 2c, from the step 2g side to the upper end 2f side. The shape is gradually widened as you go. Note that the cross-sectional shape of the bottom 2e is set, for example, in a semi-elliptical shape.

  In the step 2 according to the present embodiment configured as described above, as shown in FIG. 5, foreign matter 5 such as pebbles and dust enters the cleat groove 2b and is stepped on by the passenger and pushed in the direction of the bottom 2e. When this occurs, it is locked by the step 2g and is sandwiched in the first space 2c. As shown in FIG. 6, the same applies to the case where a foreign material 6 larger than the foreign material 5 has entered the cleat groove 2b. The large foreign material 6 is reliably locked to the step portion 2g, and in the first space portion 2c. It is in a state of being pinched strongly.

  Thus, even when the foreign objects 5 and 6 enter the cleat groove 2b of the step 2 and get caught, when the step 2 moves and reaches the entrance / exit, it is provided on the floor board of the entrance / exit as shown in FIG. The tip 4a of the comb tooth 4 engages with the cleat groove 2b.

  That is, in this embodiment, the tip 4a of the comb tooth 4 enters the second space 2d of the cleat groove 2b as the step 2 moves. As a result, the foreign matter 5 or the large foreign matter 6 sandwiched between the cleat grooves 2 b is pushed up along the upper surface of the comb teeth 4, and these foreign matters 5 and 6 are automatically and reliably removed by the movement of the step 2. be able to.

  In the step 2 according to the present embodiment configured as described above, even when the foreign matter 5 or 6 enters from the upper end portion 2f of the cleat groove 2b and is caught in the middle portion of the cleat groove 2b that becomes gradually narrower, When the step 2 reaches the entrance / exit, the foreign objects 5 and 6 can be removed from the cleat groove 2b as described above. That is, in this embodiment, even when the foreign matter that has entered the cleat groove 2b is a foreign matter 5 as well as the foreign matter 5, the comb teeth that engage with the cleat groove 2b as the step 2 moves. 4 can be easily removed from the cleat groove 2b. Therefore, according to this embodiment, the discomfort experienced by the passenger due to the foreign objects 5 and 6 sandwiched between the cleat grooves 2b can be reduced. Further, the work for removing the foreign matter caught in the cleat groove 2b is not required, and the maintenance management of the step 2 is simplified.

  Further, in the present embodiment, the space where the tip 4a of the comb tooth 4 can be inserted is controlled by the restriction portion for the foreign matter 5 and 6 that has entered the cleat groove 2b, that is, the drop in the bottom portion 2e direction by the step portion 2g. 2e can be surely formed, and a highly accurate removal performance for the foreign substances 5 and 6 sandwiched between the cleat grooves 2b can be ensured.

  That is, in the present embodiment, the tip 4a of the comb tooth 4 can be inserted into the second space 2d in a state where the foreign objects 5 and 6 that have entered the cleat groove 2b are held in the first space 2c. The foreign substances 5 and 6 can be reliably removed.

  Further, in the present embodiment, the cleat groove 2b is set to have a shape that gradually widens from the bottom 2e side to the upper end 2f side, so that relatively large foreign matter 6 on the tread 2a also positively increases the cleat groove 2b. Can be kept in the middle of the cleat groove 2b, and relatively large foreign matter 6 can be reliably removed by the comb teeth 4 inserted in the vicinity of the bottom 2e. .

  Further, in the present embodiment, since the cross-sectional shape of the bottom 2e of the cleat groove 2b is set to be semi-elliptical, that is, the bottom surface of the bottom 2e is set to a curved surface, small foreign matters such as dust collect on the bottom 2e of the cleat groove 2b. Even in such a case, the accumulated foreign matter can be easily removed.

  The present invention is not limited to the above-described embodiments, and can take various forms. For example, the cleat groove 2b may be configured not to have the step portion 2g. Further, the first space portion 2c forming the cleat groove 2b may be formed in a cylindrical space in which the diameter dimension from the step portion 2g to the upper end portion 2f is constant. Further, for example, the restricting portion may be constituted by a plurality of protrusions arranged at predetermined intervals in the circumferential direction instead of the step portion 2g.
