Abstract: A deep groove ball bearing includes an outer ring, an inner ring, a plurality of balls, and a seal member. An axial cross-sectional width is smaller than a radial cross-sectional height, a thickness of the inner ring is greater than a thickness of the outer ring, and a pitch diameter of the ball is larger than a median diameter between an inner diameter of the inner ring and an outer diameter of the outer ring A radial dimension between an outer diameter of a shoulder portion of the inner ring and an inner diameter of the seal member is greater than the thickness of the outer ring. As a result, width and weight can be reduced, a load capacity can be secured, grease leakage can be prevented, and a service lifespan can be extended.

Abstract: Cooling air conveyed through a cooling duct 3 is supplied to a discharge lamp 10 via a cooling air exit 21 having a plurality of flow paths 23a to 23c partitioned by a partition plate 22. An air flow direction changeover section 24 changes a flow path through which the discharge lamp is supplied with the cooling air from the cooling air exit. An air flow blocking ball 25 in the air flow direction changeover section moves by its own weight through a guide portion 26 to thereby block the flow path of the cooling air exit. This allows the cooling air to be directed specifically toward an upper side 11a in a direction of gravity of a lamp bulb of the discharge lamp to eliminate a temperature difference, even if a mounting style of the discharge lamp is varied among desk mounting, ceiling mounting, and vertical mounting.
