A yarn winding machine comprising: a package holding section adapted to rotatably hold a package around which a yarn is wound; a winding drum adapted to rotate while making contact with the package; a moving mechanism adapted to receive a supply of fluid and to move the package holding section in a first direction and a second direction based on pressure of the fluid, the first direction being a direction in which the package holding section approaches the winding drum, and the second direction being a direction in which the package holding section moves away from the winding drum; and a control section adapted to control the supply of the fluid to the moving mechanism, wherein, when a supply of electricity stops, the control section is adapted to control the supply of the fluid to the moving mechanism such that pressure of the fluid for moving the package holding section in the second direction becomes higher than pressure of the fluid of when the package holding section is moved in the first direction and the package is making contact with the winding drum, characterized by a supplying section (66, 69) adapted to supply the fluid to the moving mechanism, wherein the control section is adapted to control the supply of the fluid from the supplying section (66, 69) to the moving mechanism, wherein the moving mechanism includes a first moving section adapted to move the package holding section to the first position, and a second moving section provided integrally with the first moving section and adapted to move the package holding section to the second position together with the first moving section, wherein the supplying section (66, 69) includes a first supplying section adapted to supply the fluid to the first moving section and a second supplying section adapted to supply the fluid to the second moving section, and wherein the control section is adapted to control the supply of the fluid from the first supplying section to the first moving section and the supply of the fluid from the second supplying section to the second moving section, wherein the first moving section and the second supplying section are connected via a solenoid valve, wherein pressure of the fluid supplied from the second supplying section is set higher than pressure of the fluid supplied from the first supplying section, and wherein the control section is adapted to control the solenoid valve, when the supply of the electricity is stopped, such that the fluid is supplied from the second supplying section to the first moving section. a package holding section adapted to rotatably hold a package around which a yarn is wound;
