WIPO Patent Application WO/2020/012989

A1

Through the present invention, a satellite signal of a QZSS satellite is readily received even in a work machine having a GNSS positioning device. A work machine (1) is provided with a first GNSS positioning device (31) capable of positioning on the basis of a first satellite signal transmitted from a GNSS satellite (101), a QZSS positioning device (32) capable of outputting correction information on the basis of a second satellite signal transmitted from a QZSS satellite (102), a first support bracket (141) to which the first GNSS positioning device (31) is attached, and a second support bracket (142) to which the QZSS positioning device (32) is attached and which is connected to the first support bracket (141). The work machine (1) is also provided with a fastener (131f) for fixing the first support bracket (141), the first support bracket (141) and the second support bracket (142) are disposed so as to at least partially overlap, and the fastener (131f) jointly fastens the first support bracket (141) and the second support bracket (142).
