る構造になつている。(Prior art) When installing a floor mat on the floor of an automobile, especially on the floor of the driver's seat, the floor mat is secured using a locking device to prevent it from shifting in the horizontal direction, especially in the longitudinal direction. It is fixed to the floor. The locking tool used here involves inserting a hook-shaped locking part into a locking hole drilled in the floorboard, and then horizontally locking the locking part to the lower edge of the locking hole. The structure is such that an opening of an eyelet fitting provided on the floor mat is fitted into the mat locking portion that projects upward.

る。(Problem to be solved by the invention) However, most of the above-mentioned locking devices are mainly molded from plastic, and when a large horizontal force is applied to the floor mat, for example,
When a driver presses his/her foot down to perform a driving operation, the shearing force applied to the mat locking portion through the eyelet fitting becomes excessive, which may cause problems such as breakage. Therefore, it is conceivable to increase the size of the eyelet fittings and thicken the mat locking portions that are engaged with the eyelet fittings, but this causes another problem in that the eyelet fittings stand out and spoil the appearance of the floor mat.

An automobile configured to lock the floor mat 5 by fitting an opening 6A of an eyelet fitting 6 provided in the floor mat 5 into a mat locking part 4C protruding from the locking tool 4. In the locking structure of the floor mat, the locking tool 4 has a locking mechanism that is attached to the outer peripheral edge 6B of the eyelet fitting 6 in a state where the opening 6A of the eyelet fitting 6 is fitted into the mat locking part 4C. An engaging edge 4E that engages in the direction of the plane of the floor mat 5 is formed.

In the figure, reference numeral 1 is the floor surface of the automobile, and an interior covering material 1B is laid on the floorboard 1A. A locking hole 2 is bored in the floor surface 1, into which a rubber grommet 3 is fitted if necessary. Locking portion 4 fitted into the locking hole 2
The locking tool 4 having A is made of, for example, hard synthetic resin, and has a flat body portion 4B that extends along the floor surface 1.
It has a locking portion 4C that projects upward at a position away from the locking portion 4A. The locking portion 4C has a columnar shape, and a forward-facing retaining beat 4D is formed at its upper end. It is desirable that the outer shape of the beat 4D is an ellipse with the longer diameter extending in the pulling direction as shown in the drawing.

It is configured in the shape of a split hook with vertical grooves 7 on the sides. By forming the split hook into such a shape, the tensile force can be effectively absorbed, and the thickness of the locking portion 4A can be made close to the diameter of the locking hole 2. Thereby, it is possible to ensure sufficient strength to receive the horizontal force applied to the floor mat 5. In the figure, reference numeral 4H is an engagement beat formed at the lower end of the locking part 4A to prevent it from coming off, and when the locking part 4A is inserted into the locking hole 2, the bottom surface of the floorboard 1A It is engaged with the edge of the locking hole 2.
