A nozzle of a cleaner includes: a housing; a rotation cleaning unit accommodated in the housing and configured to clean a surface based on a rotation operation; and a drive unit inserted into a side of the rotation cleaning unit. The drive unit includes a motor, a motor supporter fixed to the housing and coupled to the motor, a gear unit connected with a rotation shaft of the motor to transfer a driving force, and a shaft connected to the gear unit and the rotation cleaning unit to transfer a rotation force to the rotation cleaning unit. The motor includes a printed circuit board (PCB) installation portion in which a PCB is installed and which is spaced apart from the motor supporter, in which a first space portion in which the air flows is formed between the motor supporter and the PCB installation portion.
