[0011]
Then, by welding the required portions of the left and right side edges 5a, 5a and the rear edge 5b of the mounting piece 5 to the back surface of the groove cover 6, a plurality of positions are provided at predetermined positions on both side edges of the groove cover 6. The splash prevention device 1 is fixed.
[0012]
In this configuration, as shown in FIGS. 2 and 3, when the groove cover 6 is placed on the cover receiving frame 9 of the groove 8, the elastic pressure contact piece 3 folded upward from the lower end of the vertical piece 2 is formed. By elastically contacting the inner surface 10 of the groove 8, a holding action of the groove lid 6 can be obtained, and jumping up due to impact can be prevented.
[0013]
On the other hand, when cleaning the groove 8 or the like, as shown in FIG. 4, when the groove lid 6 is removed from the lid receiving frame 9 and placed on the road 11, the pressure is applied from above by accidentally stepping on. Thus, the pressure is supported by the vertical reinforcing wall portions 4 and 4 that substantially coincide with the vertical dimension of the vertical piece portion 2, and deformation of the vertical piece portion 2 is prevented. Here, the reinforcing wall portions 4, 4 are coupled to the side portions of the vertical piece portion 2, and the reinforcing wall portions 4, 4 are provided so as to be substantially orthogonal to the vertical piece portion 2. , 4 and the vertical piece 2 have an effect of supporting each other against both deformation forces in the front-rear direction and the left-right direction, so that strong robustness can be obtained.
