It is not necessary to support special parts such as wiring harnesses and cables, but can help reduce the number of parts. Further, a secondary air filter 63 for purifying the secondary air of the exhaust system supplied to the engine E is arranged on the outside of the vehicle body frame 25 and supported by the rear frame pipe 29 on the left side. To make maintenance of the secondary air -22- (18) (18) 593042 air filter 63 easy. The downstream end of the suction pipe 64 is connected to the suction port of the secondary air air benefit 63. The upstream end of the suction pipe 64 is such that the sound insulation material 65 is interposed with the right rear skeleton pipe 3. Is inserted into the rear end opening 30c of the rear skeleton tube 30 between the inner surfaces of the rear frame. Therefore, the suction pipe 64 can be connected to the rear frame pipe 30 without the need to install extra parts to reduce the cost. In addition, between the upstream end of the suction pipe 64 and the inner surface of the rear frame pipe 30, a The sound-insulating material 65 that allows air to circulate, so that the echo of the inhalation sound can be suppressed in the rear skeleton pipe 30 to achieve a sound-extinguishing effect. In addition, the secondary air control valve 66 installed between the engine E and the secondary air filter 63 and supported by the vehicle body frame 25 is a part of the vehicle body frame 25, that is, after being clamped. The upward skeleton portion 29 a of the skeleton tube 29 is disposed on the side opposite to the secondary air filter 63, so the secondary air filter 63 and the secondary air control valve 66 are disposed adjacent to each other, and It can be used to simplify the structure of the connection between the secondary air filter 63 and the secondary air control valve 66. Furthermore, the 'body frame 25 is provided with a pair of left and right rear skeleton tubes 29 and 30 which open and close each other at the rear end, and either of these rear skeleton tubes 29 and 30 is the rear skeleton. The rear end of the tube 30 is open, and the upstream end of the suction pipe 64 is inserted. Therefore, it is not necessary to apply extra processing to the rear framework pipe 30 in order to connect the suction pipe 64 to the rear framework pipe 30, and the cost can be further reduced. Moreover, the rear end of the other rear skeleton tube 29, which is a pair of left and right rear-facing openings that are opposite to each other and opened, is inclined (19) (19) 593042. The surface 29c and the suction pipe 64 are arranged along the inclined surface 29c, so that the suction pipe 64 can be inserted into the rear opening 30c of the rear frame pipe 30 without increasing the bending of the suction pipe 64, and the suction pipe The inspiratory flow within 64 is good.
