Claim 3:
4. A remote operation device for remotely operating a construction machine having an attachment from a remote place distant from the construction machine, the remote operation device comprising:
a vibration detector configured to detect a plurality of vibration components in a plurality of directions different from each other, the vibration components being included in a vibration caused on the attachment;
a transmission device that transmits vibration information on the vibration of the attachment to an operator in the remote place; and
a transmission control section that controls an operation of the transmission device,
wherein a vibration determination condition for determining whether the vibration of the attachment is a vibration caused by the attachment's coming in contact with a different object is set in advance,
the vibration determination condition includes a condition that an amplitude of a maximum vibration component largest in amplitude among the plurality of vibration components detected by the vibration detector is equal to or larger than a preset amplitude threshold,
the transmission control section controls an operation of the transmission device to allow the vibration information to be transmitted to the operator only when the vibration determination condition is met,
the remote operation device further comprises a remote operation lever to which an attachment operation is applied by the operator in the remote place, the attachment operation being an operation for causing the attachment to move,
wherein the vibration determination condition further includes a condition that the attachment operation has been applied to the remote operation lever.
