An exhaust device (20) for a saddle-type vehicle having a pipe section (19) with respect to a vehicle body and housing a catalyzer (C) therein, and a muffler (26) connected to a rear end of the pipe section (19) includes an upstream oxygen sensor (U) positioned upstream of the catalyzer (C) and a downstream oxygen sensor (D) positioned downstream of the catalyzer (C). The downstream oxygen sensor (D) is disposed in either a position overlapping a main stand (22) for supporting a motorcycle (1) as viewed from below the vehicle body when the main stand (22) is stored, or a position overlapping a stand receiver (90) for abutting against the main stand (22) as viewed from below the vehicle body when the main stand (22) is stored. The pipe section (19) includes a larger-diameter portion (61) having an increased diameter for housing the catalyzer (C) therein.
