That is, in order to remove foreign substances introduced into the recessed and recessed grooves 12 during cleaning, foreign substances are swept away in the longitudinal direction of the grooves 12 by using a brush or a broom to clean the foreign substances. At this time, The foreign matter sticking to the deep corner of the right angle jaw 14 is difficult to remove and is pointed out as a main factor for contaminating the step 13 as well as making it difficult to clean because it is caught by the right angle jaw 14 formed in the portion there was.

3, when the step 18 is made of stone, a plurality of grooves 15 are directly formed on the surface of the stone tread 17 by using a tool such as a disk-shaped diamond grinder There is also a non-slip material to be processed. The grinder shape is maintained at the end of the groove and the gentle slope 16 is formed naturally, which facilitates cleaning. However, when the stair tread is made of concrete, There was a limitation in that the grooves could not be directly processed in the concrete due to the fear of breakage.

In consideration of this point, it is also conceivable to form the soft ridge only in the soft ridge 10 shown in FIGS. 1 and 2, but it is not possible to perform extrusion molding in which a constant section is continuously formed, It can be formed by casting and cutting. However, since the manufacturing cost is greatly increased as compared with the extrusion molding, it is difficult to apply and it is required to improve the rice cultivation with a structure that can be manufactured more easily.
