Abstract: A construction machine includes a control device having a reaction-force correction control section. When a difference between a target operator input and an actual operator input for a front member exceeds a preset range, the reaction-force correction control section executes correction to increase an operation reaction force to be applied by a reaction-force applying device to an operating unit operating an actuator driving the front member. When the difference falls within the range, the reaction-force correction control section executes correction to decrease the operation reaction force to be applied by the reaction-force applying device to the operating unit operating the actuator driving the front member.
