PROBLEM TO BE SOLVED: To provide a dust removing implement capable of easily moving a rake portion in a vertical direction along a bar. SOLUTION: A base portion 3 is equipped with a guide portion 4 which is arranged in the state of protruding from the base portion 3 and which guides the bar 91, so as to move along the bar 91 in the state of being separated from the bar 91. The rake portion 5 is constituted in such a manner as to be switchable between a duct removal position to enable duct removal by protruding each tooth 51 with respect to the guide portion 4, and a receding position to recede from the duct removal position so as to prevent the respective teeth 51 from becoming a hindrance to movement along the bar 91 during the movement.
