なことがない。[0009] With the above-described structure, the short leg 3 with the locking plate 4 is normally provided in the deformed long hole 12 provided near the edge of the speaker hole 11 of the mounting board 10 from the front side. The fitted speaker grille 1
The small projection 6 provided on the inner surface of the locking plate 4 outside the short leg 3 is engaged with the engaging small hole 13 provided outside the locking narrow portion 12b at one end. In this state, the up end 5a side of the inclined inner surface 5 of each locking plate 4 is attached to the mounting board 1.
Since the speaker grill 1 is closely attached to the back surface of the mounting board 10, the speaker grill 1 is held in a state without rattling with respect to the mounting board 10. Therefore, even if the number of fixed portions is reduced, the speaker is rattled by running vibration. It does not come and go.

The speaker grill 1 is pushed in with the locking plate 4 corresponding to the plate loading portion 12a of the deformed elongated hole 12 provided at the inner side of the locking plate 12 and the speaker grill 1 is provided on the inner surface of the locking plate 4. The hemispherical small projection 6 is rotated only to a position where it engages with the small engaging hole 13 provided outside the narrow narrowing portion 12b at one end of the deformed long hole 12, and the plate for locking is formed. The inner surface 5 of the piece 4 is brought into close contact with the back surface of the mounting board 10 due to its own elasticity, and the assembly is completed. After that, full-scale fixing such as screwing or crushing welding of the boss portion is performed as necessary. Good,
Thus, even in the case of performing full-scale fixing, the small holes 13 for engagement are used.
The work can be simplified by being held by the engagement of the small projections 6 with the small projections 6 and the close contact of the inner surface 5 of the locking plate 4 with the mounting board 10 on the up end 5a side. Since the attaching operation is extremely easy, it can be provided at low cost.

相俟ち実用的価値極めて大なものである。As is apparent from the above description, the present invention provides a mounting board having a deformed elongated hole and an engaging small hole, one end of which has a wide plate-piece insertion portion and the other end has a narrowing portion for locking. A speaker grill in which an inner surface is formed as an inclined surface at an end of a short leg portion arranged at a required interval on the back surface, and a locking plate piece provided with a small projection on an outer portion from the short leg portion is stretched. By simply turning the speaker grill in a state where the locking plate is fitted in the plate insertion portion of the deformed elongated hole of the mounting board, a full-scale operation such as screwing or crushing welding of the boss portion is performed. Even if the fixed portions are eliminated or reduced, rattling due to running vibration does not occur. Therefore, the present invention solves the problems of the conventional car stereo speaker of this type, and has a very large practical value in combination with the advantage that the structure is simple and the assembling operation is easy. It is.
