み止めの為に凸起３が設けられていた。(Prior Art) Conventionally, for example, when a speaker unit is attached to a baffle plate of a speaker box, a fixing nut 1 with a substantially cylindrical protrusion having a collar portion 2 and a protrusion 3 as shown in FIG. 3 is previously attached to the baffle plate. The speaker unit is mounted by inserting the mounting bolt from the front side of the speaker unit through the mounting frame of the speaker unit from the rear side and screwing it into the screw 4 of the fixing nut 1 with the protrusion. It was A protrusion 3 was provided around the fixing nut with a protrusion to prevent loosening.

In the drawing, a fixing nut 10 with a steel projection has a collar portion 2, and a protrusion 5 having elasticity is provided on the back surface side of the jaw portion 2 in a direction in which a cylindrical portion is press-fitted.
This protrusion is formed to have elasticity by, for example, punching shaping. The other parts are the same as those in FIG. 3, and therefore the same reference numerals are given and detailed description thereof is omitted.

が回転して緩み始めてしまう。In order to mount the speaker unit using such a fixing nut with a projection, as shown in FIG. 2, a fixing nut 10 with a projection is provided on a wooden baffle plate 11 having a prepared hole 8 so that the collar portion is raised. Hit until 5 is stuck. On the other hand, the mounting bolt 6 is inserted through the prepared hole 9 of the frame 7 of the speaker unit and screwed into the fixing nut 10 with the projection. The frame 7 of the speaker unit is clamped together with the wooden baffle plate 11 between the collar portion 2 of the fixing nut 1 with a protrusion and the head of the bolt 6, and the wooden baffle plate 11 receives pressure in the plate thickness direction by this clamping. . The bolt 6 is held by the repulsive force due to the tightening of each component, the frictional resistance force at the contact surface between the head of the bolt 6 and the frame 7 of the speaker unit, and the screw portion of the fixing nut 1 with protrusions. Is fixed. However, the wooden baffle plate 11 is compressed by the tightening pressure for a long period of time and contracts in the plate thickness direction. In the case of the conventional fixing nut, since the positional relationship with the bolt does not change, the tightening force of the frame 7 on the wooden baffle 11 is significantly reduced, and the bolt rotates due to the vibration when driving the speaker unit. Start to loosen.

み始めるのを防止することができる。Therefore, if the fixing nut 1 with a protrusion of the present invention is used, it is possible to prevent the tightening force of the frame 7 on the wooden baffle 11 from being greatly reduced by the spring effect of the protrusion 3, and the bolt is generated by the vibration when the speaker unit is driven. It is possible to prevent 6 from rotating and starting to loosen.

る。(Effect) As described above, according to the present invention, since the flange of the fixing nut with the protrusion is provided with the elastic protrusion, it is firmly fixed to the wooden part and the wooden baffle plate is arranged in the plate thickness direction. It is possible to prevent the tightening force of the bolt from being significantly reduced and prevent the bolt from starting to loosen even if the bolt contracts due to the compression force.
