A construction machine comprising: a lower travelling body; an upper slewing body mounted on the lower travelling 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 travelling body, the upper slewing body, the working device, and the attachment; a vibration applying device (64, 65) which applies a vibration to a target portion (61, 62, 63) 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; and a control device (56, 72) which controls an operation of the vibration applying device (64, 65), wherein the vibration applying device (64, 65) is configured to perform a first vibration applying operation for applying a vibration having a first vibration pattern to the target portion (61, 62, 63), 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 (61, 62, 63), the control device (56, 72) is configured to cause the vibration applying device (64, 65) 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 (64, 65) 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 target track (R1, R2) which is a target of a track drawn by the specific portion when the specific portion moves from a position upwardly away from a ground toward the target position, the index value includes a distance index value which is a distance between the specific portion and the target track (R1, R2), the first condition includes a condition that the distance index value is within a predetermined first distance range, and the second condition includes a condition that the distance index value is within a predetermined second distance range different from the first distance range. a lower travelling body;
