Abstract
Provided is a working machine having an expanded range of a working device posture which permits information on an attachment of the working device to be transmitted from the attachment to a machine body through wireless communication. The working machine includes: a transmitter disposed in the attachment so as to be displaced together with the attachment relatively to the machine body and configured to send an information signal containing information on the attachment; a receiver disposed in the machine body and configured to receive the information signal; a controller which acquires information on the attachment based on the information signal received by the receiver; and a relay device disposed in the working device main body to receive the information signal sent by the transmitter and transmit the information signal to a position at which the information signal can be received by the receiver.
