PROBLEM TO BE SOLVED: To prevent a damper tube from being removed from a pump frame by providing a damper tube for pressing a pulley against a tube or separating the pulley therefrom forcibly and fitting the damper tube fixedly over a boss formed on the pump frame. SOLUTION: A damper tube 105 is applied over a boss 205 provided on a separation wall 108 and secured in place. Since a tube pump is stepped out when the damper tube 105 is removed therefrom by abuts against a pulley, the damper tube 105 is applied over a boss 205 having diameter larger than the hole diameter of the tube and secured surely through an adhesive. When a silicon based damper tube 105 15 employed, a silicon based adhesive is used. According to the arrangement, the damper tube can be prevented from being removed from the pump frame. |
