By the way, in this embodiment, the nail driving hole 3 is used.
5 are provided, and the wall surface 34 of the wall portion 34 is provided.
The distance from a is different. Therefore, among a plurality of nailing tools 32 prepared, those in which the distance between the protruding portion 44 and the sliding portion 47 is the same from the wall surface 34a of the wall portion 34 to the nail 23 this time (for example, FIG. 3, FIG. 5 and 6, in FIG.
(The nailing tool 32 shown in (a) is used).

Next, the sliding portion 47 of the selected nailing tool 32.
Is engaged from the opening of the guide groove 31 on the upper surface side of the wall portion 34. Then, as shown in FIG. 4B, the housing portion 31a of the guide groove 31 and the rib 47b of the sliding portion 47, and the opening portion 31b of the guide groove 31 and the sliding groove 47a of the sliding portion 47 are engaged with each other. Accordingly, the sliding portion 47 can slide along the guide groove 31 in the extending direction (vertical direction) of the guide groove 31. At this time, the engagement recess 46 of the thrust surface 45 of the nailing tool 32 is located so as to face the nailing hole 36.

Then, as shown in FIG. 5, by sliding the sliding portion 47 along the guide groove 31, the nailing tool 32 is hung, and the engaging recess 46 on the thrust surface 45 of the nailing tool 32 is removed. The head 23a of the nail 23 is engaged, and the thrust surface 45 and the head 23a of the nail 23 are brought into contact with each other. At this time, the nailing tool 32

In this state, as shown in FIG. 6, a hammer 40
When the hammer surface 41 of the nailing tool 32 is hit with the nailing tool 32, the impact of the hammer 40 through the nailing tool 32 makes contact with the thrust surface 45.
It is transmitted to 3. At this time, since the rubber plate 42 is attached to the mallet surface 41, the rubber plate 42 can reduce the impact of the hammer 40 and prevent the hammer surface 41 of the nailing tool 32 from cracking.

When the hammer surface 40 is repeatedly hit on the hammer surface 41, the sliding portion 47 slides along the guide groove 31, and the nailing tool 32 moves to mount the nail 23 on the mounting surface 21 (bottom plate 3
5) Press in the vertical direction, which is the driving direction.

In this driving operation, since the moving direction of the nail driving tool 32 is guided (restricted) by the guide groove 31, the outer frame installer is not accustomed to handling the hammer 40 and taps the same portion accurately and repeatedly. Even if it is not possible, the nail 23 can be easily driven in the vertical direction simply by repeatedly striking the hammer surface 41 of the nailing tool 32 with the hammer 40.

Further, in the present embodiment, the speaker box 19 and the wall portion 34 which occupy a large installation space in the lower side portion 33 are arranged in the vicinity of the driving position of the nail 23 to the outer frame 11. The nail 23 is driven in via the nailing tool 32. Since the sliding groove 47a of the sliding portion 47 is notched and the groove 47a is not formed up to the mallet surface 41, when the nail 23 is driven, the mallet surface 41 of the nail hitting tool 32 has the wall portion 34 (speaker). Located above box 19). Therefore, the members around the nail 23 do not hinder the driving operation of the nail 23 in terms of space.

Further, a male type or female type engaging portion is formed,
Due to the engagement relationship between the sliding portion 47 and the guide groove 31, both of which are formed in a T shape, the movement of the nailing tool 32 in the direction intersecting the vertical direction (horizontal direction) is restricted. As a result, in order to regulate the moving direction, for example, the outer frame installer manually operates the nailing tool 3
2 and the installation surface 21 (3
Since it is not necessary to move it toward 5), it is possible to improve the efficiency of the work of driving the nail 23.

Further, since the engaging recess 46 having a cross-sectional shape corresponding to the shape of the head 23a of the nail 23 is formed on the thrust surface 45 of the nailing tool 32, the nail 23 is removed from the thrust surface 45 during the work.
The head 23a of the head does not slip off. In this way, the driving of the nail 23 can be completed easily, and the lower side 33
The (outer frame 11) can be fixed to the installation surface 21.

When the nail 23 is struck, the nailing tool 32
The (sliding part 47) is removed from the guide groove 31. Then, the length from the sliding portion 47 to the protruding portion 44 as shown in FIG. 7 or 8 is made to correspond to the other nailing holes 36 (nails 23) having different distances from the wall surface 34a of the wall portion 34. The nail driving tool 32 is replaced with a different nail driving tool 32, and the nail 23 is driven again. In this way, the position separated from the guide groove 31, that is, the driving position of the nail 23 on the bottom plate 35 can be changed, and the plurality of nails 23 are brought close to each other to fix the outer frame 11 (lower side portion 33), It is possible to appropriately select the driving position according to the state of the installation frame 22.
