     At the same time of this temporarily fixing, the bag body  27  of the air bag  25  is folded and inserted into the concave storage portion  15  in the fixing portion  11 . 
     Then, as shown in FIG. 8, the respective fixing holes  29 b in the mounting piece  29  located at the end of the air bag  25  are made to correspond to the fixing holes  14 e in the mounting plate  14  of the fixing portion  11 . Successively, the respective fixing legs  33 b of the pressing plate  33  are inserted into the respective fixing holes  29 b,  14 e and fixed by peripheral parts around the respective fixing holes  14 e. As shown in FIG. 2, the fixing legs  14 c of the mounting plate  14  are inserted into the fixing holes  28 b in the mounting piece  28  of the airbag  25 . Further, the respective brackets  17  are bent so as to cover the mounting plate  14  of the fixing portion  11  such that the respective fixing legs  14 c are inserted into the respective fixing holes  18 b in the connecting plate  18  and the respective fixing legs  14 c are fixed by a peripheral part around the fixing holes  18 b. Consequently, the bag body  27  of the air bag  25  is temporarily fixed to the fixing portion  11 . 
     Next, the fixing legs  20 b,  21 b of the respective garnish bodies  20 ,  21  are inserted into the fixing holes  14 b in the fixing plates  14  of the corresponding fixing portion  11  such that they are fixed by a peripheral part around the respective fixing holes  14 b. Consequently, an assembly A 1  (see FIG. 5) in which the air bag apparatus M is contained in the garnish members  10  is formed. 
     When the garnish members  10  are installed and fixed to the body  1  for assembly work for vehicles or the like reason, the respective fixing legs  20 b,  21 b are removed from the fixing holes  14 b and then the garnish bodies  20 ,  21  are opened. As shown in FIG. 3, the four bolts  42  are engaged with the mounting holes  1 a in the body  1  via the mounting holes  18 a in the respective brackets  17 , then, the mounting holes  28 a in the respective mounting pieces  28  and finally the respective mounting holes in the mounting plates  14  of the fixing portion  11 . As shown in FIG. 7, the single bolt  43  is engaged with the mounting hole  1 b in the body  1  via the mounting hole  33 a in the pressing plate  33 , then, the mounting hole  29 a in the mounting piece  29  and finally the mounting hole  14 d in the mounting plate  14  of the fixing portion  11 . Further, as shown in FIG. 5, the two bolts  44  are engaged with the mounting holes  1 c in the body  1  via the mounting holes  36  in the respective clamps  35  and the mounting holes  14 f in the mounting plates  14  of the fixing portion  11 . Consequently, the garnish members  10  and the air bag apparatus M can be installed and fixed to the body  1 . 
     Then, the respective garnish bodies  20 ,  21  are closed such that the respective fixing legs  20 b,  21 b are inserted into the fixing hole  14 b in the mounting plate  14  of the fixing portion  11  and fixed by a peripheral part around the fixing holes  14 b. Consequently, installation and fixing of the garnish members  10  and the air bag apparatus M to the body  1  is completed. Meanwhile, a lead wire for inputting a predetermined activation signal is connected to the inflator  31 . 
     After that, if the activation signal is input to the inflator  31 , gas is injected from the gas injecting port  31 a. Then, the bag body  27  of the air bag  25  ruptures the rupture part  19 d of the respective brackets  17  so that the respective garnish bodies  20 ,  21  are opened. Then, the bag body  27  is inflated as shown by a two-dots-and-dash line in FIG. 1,  2  and FIG.  10 . 
     With the garnish members  10  according to a first embodiment of the present invention, as described above, before the garnish members  10  are fixed to the body  1 , the air bag apparatus M is temporarily fixed to the mounting plate  14  of the fixing portion by utilizing the fixing legs  33 b in the pressing plate  33 , the clips  40  for fastening the clamps  35  which connect the air bag  25  with the inflator  31 , and the fixing legs  14 c. Thus, by disposing the fixing portion  11  of the garnish members  10  on the body  1 , it is possible to dispose the air bag apparatus M at a predetermined position. As a result, the installation and fixing of the air bag apparatus M and the garnish members  10  can be achieved easily. 
     The garnish members  10  according to the first embodiment can be handled as the assembly A 1  containing the air bag apparatus M by such a temporary fixing. Thus, it is convenient for transportation, storage and the like until this assembly is installed and fixed to vehicles. 
     Further, according to the first embodiment, the bolts  42 ,  43 ,  44  as means for fixing the air bag  25  and the inflator  31  of the air bag apparatus M to the body  1  are utilized commonly as means for fixing the garnish members  10  to the body  1 . Thus, it is possible to reduce a number of parts necessary for the fixing work and a number of working steps. 
     Further, according to the first embodiment, the folded bag body  27  of the air bag  25  is pressed by the brackets  17  located at a plurality of positions. Thus, there is never a situation when the garnish bodies  20 ,  21  are opened so that the bag body  27  drops into the cabin.

     Then, an assembly A 2  (see FIG. 15,  13 ) in which the air bag apparatus M is temporarily fixed to the respective fixing portions  51 ,  65  of the garnish member  50  is formed. 
     When the garnish member  50  is installed and fixed for assembly work of vehicles, first the garnish bodies  60 ,  61  are opened. Then, as shown in FIG. 13, the four bolts  42  are engaged with the fixing holes  1 a of the body  1  via the mounting holes  18 a in the respective brackets  17 , the mounting holes  28 a in the respective mounting pieces  28 , and the respective mounting holes  54 a in the mounting plates  54  of the respective fixing portions  51 . Further, in FIG. 7 where the mounting plate  14  is used, the single bolt  43  is engaged with the mounting hole  1 b of the body  1  via the mounting hole  33 a in the pressing plate  33  and the mounting hole  29 a in the mounting piece  29 . Still further, as shown in FIG. 15, the single bolt  44  is engaged with the mounting hole  1 c of the body  1  via the mounting hole  71 a in the clamping portion  69 , and the mounting hole  68 a in the mounting plate  68  of the fixing portion  65 . Consequently, the garnish members  50  and the air bag apparatus M can be installed and fixed to the body  1 . 
     Then, the respective garnish bodies  60 ,  61  are closed and the respective fixing legs  60 b,  61 b are inserted into the fixing holes  1 d provided in the body  1  and fixed in a peripheral part around the fixing holes  1 d. Consequently, installation and fixing of the garnish members  50  and the air bag apparatus M to the body  1  can be achieved. Meanwhile, a lead wire for inputting a predetermined activation signal is connected to the inflator  31 . 
     After that, if the activation signal is input to the inflator  31 , gas is injected from the gas injecting port  31 a. Then, the bag body  27  of the air bag  25  ruptures the rupture part  19 b of the respective brackets  17  so that the respective garnish bodies  60 ,  61  are opened. Then, the bag body  27  is inflated as shown by a two-dots-and-dash line in FIG.  11 .
