Abstract: A connector (1) is constituted by a first member (10) and a second member (40). The first member (10) has a male connecting portion (11) at a first end and a screwing structure (26) at a second end. The male connecting portion (11) is inserted into a female connecting portion (41) of the second member (40). A first engagement structure (15) is provided on the first member (10), and a second engagement structure (45) is provided on the second member (40) so as to be able to abut against the first engagement structure (15) in the circumferential direction. When a rotational force of a predetermined value or greater is applied to the first member (10) in a tightening direction (R1) of the screwing structure (26), one of the first engagement structure (15) and the second engagement structure (45) is plastically deformed by the other, so that the first member (10) is then rotatable in both forward and reverse directions relative to the second member (40).

Abstract: A quartz glass provides an opaque quartz glass having high light-shielding property, excellent mechanical strength and excellent cleaning resistance against hydrofluoric acid. By setting the maximum width of the amorphous bubbles existing in the opaque quartz glass to an average of 3 to 15 ?m and the density to 2.15 g/cm3 or more, the mechanical strength after baking and the cleaning resistance by hydrofluoric acid are improved. The opaque quartz glass has a whiteness at a thickness of 10 mm of 75 to 90%, the reflectance of light with a wavelength of 0.24 to 2.6 ?m at a thickness of 4 mm is 60 to 85%, and the bending strength after baking is 95 MPa. In addition, a foaming agent may be mixed in the opaque quartz glass. An opaque quartz glass having cleaning resistance against acid can be obtained.

Abstract: A vehicle headlamp with a shade whose vibration resistance strength can be sufficiently secured on keeping the appearance of lamp fixture from being deteriorated. A fitting-stay fixing portion (28) for fixing a fitting stay (26) of a shade (22) is provided at the back of a reflective surface (20a) of a reflector (20). Thus, the structure of the fitting-stay fixing portion (28) is prevented from being seen when the lamp fixture is seen from its front side. A reflective region (20a1) positioned at the front of the fitting-stay fixing portion (28) of the reflective surface (20a) is so formed as to project forward relative to reflective regions (20a2) adjacent to the reflective region (20a1) at the front of the fitting-stay fixing portion, whereby the position of arranging the fitting-stay fixing portion (28) can be set close to the center of gravity of the shade (22). Therefore, the inertia of moment of the shade (22) can be lowered by decreasing the length of the lever of the fitting stay (26).
