A color cathode ray tube according to this invention comprises a cylindrical neck section having an electron gun which emits three electron beams, a funnel section extending from the neck section, and a panel section having a faceplate on which an image is formed. Phosphor stripes for emitting red, green, and blue light rays, upon electron beams landing thereon, are formed on an inner surface of a faceplate of the panel. A shadow mask having slit apertures for directing the three electron beams onto the corresponding phosphor stripes is arranged in the panel, and is welded to a mask frame which is suspended and supported on the panel by supporting structures welded to the frame. Each supporting structure comprises a fixed section secured to the frame, and a movable section having a hole into which a panel pin is fitted. The supporting structures are strongly resistant to impact forces, as a result of having twist-prevention sections which are fixed close to a movable section thereof which is liable to plastic deformation.
