PROBLEM TO BE SOLVED: To provide a cylindrical sewing machine in which a lubricating oil can be prevented from being leaked from a cylindrical part, or the like, without increasing components. SOLUTION: A bed part 25 comprising the lower part of a frame 23 of the cylindrical sewing machine 21 and a cylindrical part 27 attached to the tip of the bed 25 are formed into a closed structure having ceiling parts 25b and 27b covering the upper face, and an opening itself to become a cause of spilling or leaking of the lubricating oil is eliminated. Thus, the lubricating oil is prevented from being leaked from the cylindrical part 27, or the like, without increasing components.
