A cathode ray tube includes an electron gun for emitting at least one electron beam; a mask frame include a mask having a plurality of holes or slits for allowing the electron beam to be transmitted therethrough and a frame to which the mask is attached; and a panel including a phosphor layer to be scanned by the at least one electron beam transmitted through the plurality of holes or slits of the mask. The panel includes a plurality of stud pins for supporting the frame. The frame includes a plurality of elastic supports engaged with the plurality of stud pins. At least one of the plurality of elastic supports includes an engagement portion having an engaging hole which is engaged with one of the plurality of the stud pins and an elastic portion in contact with the one stud pin. Mask frame vibration causes the elastic portion to rub against a respective stud pin so as to generate a frictional force for attenuating the vibration of the mask frame.
