摘要： A cathode ray tube has a vacuum enclosure including a panel (1) having a screen (1a), a funnel (2) connected to the panel (1), and a neck (3) connected to the narrow part of the funnel (2). The funnel (2) has a yoke-mounting portion (5) on which a deflection yoke (7) is mounted. The sectional shape of the yoke-mounting portion (5), cut by a plane perpendicular to the tube axis of the funnel (2), varies from a circular shape to a substantially barrel shape having a maximum dimension at least in a direction of the horizontal axis or the vertical axis, as the position shifts from the neck (3) side to the panel (1) side of the yoke-mounting portion (5). With such an arrangement, the resistance to the external pressure can be improved, and the deflection power consumption can be reduced.
