Claim 10:
11. A construction machine, comprising:
a lower traveling body;
an upper slewing body mounted on the lower traveling body so as to be slewable;
a working device rotatably connected to the upper slewing body;
an attachment connected to a distal end of the working device;
an operation part which receives an operation by an operator for operating at least one of the lower traveling body, the upper slewing body, the working device, and the attachment;
a vibration applying device which applies a vibration to a target portion that is at least a part of a portion which is brought into contact with a body of the operator who operates the operation part;
a storage part which stores an operation target set as a target of an operation of the construction machine for moving a specific portion of the construction machine to a target position set as a destination to which the specific portion of the construction machine moves;
a calculation part which calculates an index value which serves as an index indicating a deviation between the operation target and an actual state of the construction machine;
a control device which controls an operation of the vibration applying device; and
a target generation part which generates the operation target, wherein
the vibration applying device is configured to perform a first vibration applying operation for applying a vibration having a first vibration pattern to the target portion, and a second vibration applying operation for applying a vibration having a second vibration pattern different from the first vibration pattern to the target portion,
the control device is configured to cause the vibration applying device to perform the first vibration applying operation when the index value calculated by the calculation part satisfies a predetermined first condition, and to cause the vibration applying device to perform the second vibration applying operation when the index value calculated by the calculation part satisfies a predetermined second condition different from the first condition,
the operation target includes a deceleration target timing which is a target of a timing at which the upper slewing body starts a deceleration operation in response to a slewing deceleration command operation given to the operation part, the slewing deceleration command operation being an operation for stopping a slewing operation of the upper slewing body, and
the target generation part calculates an estimated required time from a point of time at which it is assumed that the operation part receives the slewing deceleration command operation until the slewing operation is stopped, and calculates the deceleration target timing based on information including at least the estimated required time.
