移動可能な大きさに設定されている。FIGS. 1 and 2 show a main part of an exhaust passage of an automobile according to an embodiment of the present invention. A mounting plate of a passage switching valve 25 is provided at a branch 7 between the exhaust passage 2 and the bypass passage 4. A base 8 of the mounting plate 8 is fixed by a screw 12 to a rotating shaft 11 that is rotated by an intermediate arm 10 that is interlocked with an actuator 9 described later. Bolts 17 and 18 are provided in the middle of the mounting plate 8.
Through holes 8a and 8b are formed. Numerals 15 and 16 denote valve bodies mounted on both sides of the mounting plate 8.
a, 16a are tapered or spherical in accordance with the tapered or spherical seating surfaces of the valve seats 20, 19 provided on the inner peripheral surfaces of the bypass passage 4 and the exhaust passage 2; ,
Bolt insertion holes 15b and 16b and bolt through holes 15c and 16c are formed in accordance with the number of bolts, respectively. The bolt insertion holes 15b and 16b are set to a size that allows the valve bodies 15 and 16 to move relative to the mounting plate 8 with the heads of the bolts 18 and 17 inserted.
ここで流体切替バルブ25の取付プレート８に対する各
弁体15、16の取付けは次の通りである。Here, the mounting of each valve element 15, 16 to the mounting plate 8 of the fluid switching valve 25 is as follows.
まず、取付プレート８に一方の弁体15を取付ける場合
