In the present invention, a notch or a convex part protruding inward is formed in the cylindrical part, and the inner diameter of the cylindrical part or the diameter of the arc where the inner end of the convex part of the cylindrical part is located is determined by the diameter of the exhaust pipe. Since the diameter is smaller than the outer dimension, when an exhaust pipe whose diameter is larger than the inner diameter of the cylindrical part is inserted into the cylindrical part, the diameter of the cylindrical part expands. Therefore, even if there is slight variation in the inner diameter of the cylindrical portion and the outer dimension of the exhaust pipe, the exhaust pipe can be reliably fitted into the cylindrical portion.
以下、本考案の詳細を図面に示す実施例につい
て説明する。
Hereinafter, details of the present invention will be described with reference to embodiments shown in the drawings.

ることとなる。 In the finisher having the support member configured as described above, the notch 39 is formed in the cylindrical portion 35, so that the cylindrical portion 35 can elastically expand in diameter. Therefore, the exhaust pipe 33 having an outer diameter larger than the inner diameter of the cylindrical portion 35 is connected to the cylindrical portion 3.
5, the cylindrical portion 35 elastically expands in diameter. As a result, even if there is slight variation in the inner diameter dimension of the cylindrical portion 35 and the outer dimension of the exhaust pipe 33, the exhaust pipe 33 can be reliably fitted into the cylindrical portion 35.

る。 That is, the external dimensions of the exhaust pipe 33 are the same as the cylindrical portion 35.
Since the exhaust pipe 33 can be easily inserted into the cylindrical part 35 even when the inner diameter is larger than the inner diameter of the
By setting the outer dimension of the exhaust pipe 33 to be larger than the inner diameter dimension of the cylindrical portion 35 in advance, the cylindrical portion 35
This eliminates the formation of a gap between the exhaust pipe 33 and the exhaust pipe 33, making it possible to reliably prevent chatter noise and the finisher from falling off the exhaust pipe 33.

A cylindrical fixing portion 45 is formed. A cylindrical portion 47 is formed in the center of the support member main body 41.
An inner flange 49 is formed at the end.

実に嵌合されることとなる。 In the finisher having the support member configured as described above, the convex portion 51 is formed on the cylindrical portion 27, so that it is possible to elastically expand the diameter of the arc where the inner end of the convex portion 51 is located. Therefore, when an exhaust pipe 53 having an outer dimension larger than the diameter of the arc where the inner end of the convex portion 51 is located is inserted into the cylindrical portion 47, the diameter of the arc where the inner end of the convex portion 51 is located elastically expands. As a result, even if there is some variation in the inner diameter dimension of the cylindrical portion 47 and the outer dimension of the exhaust pipe 53, the exhaust pipe 53 is reliably fitted into the cylindrical portion 47.
この結果、筒状部４７と排気管５３との間に間

美観を向上することができる。 As a result, no gap is formed between the cylindrical portion 47 and the exhaust pipe 53, and it is possible to reliably prevent chatter noise and the finisher from falling off the exhaust pipe 53. Further, in the support member configured as above, the terminal end of the exhaust pipe 53 is completely hidden by the inner flange 49, so that
The aesthetic appearance can be improved.

As described above, according to the present invention, a notch or a convex portion protruding inward is formed in the cylindrical portion, and the inner diameter dimension of the cylindrical portion or the inner end of the convex portion of the cylindrical portion is located. Since the diameter of the arc is smaller than the external dimensions of the exhaust pipe, even if there are slight variations in the internal diameter of the cylindrical part and the external dimensions of the exhaust pipe,
There is an advantage that the exhaust pipe can be reliably fitted into the cylindrical part.
