Abstract: Provided is an industrial robot including a lifting mechanism which lifts and lowers an arm support member and a housing inside which the lifting mechanism is disposed, and an opening part for connecting the arm support member disposed outside the housing with the lifting mechanism is formed in a side face of the housing. In the industrial robot, even when dust generated inside the housing can be prevented from flowing out from the opening part, the cost can be reduced. In the industrial robot, the lifting mechanism which lifts and lowers the arm support member is disposed inside the housing. A side face of the housing is formed with the opening part for connecting the arm support member disposed outside the housing with the lifting mechanism disposed inside the housing, and the arm support member is fixed with the flat plate-shaped cover members and for closing the opening part.
