Abstract: A joint portion is provided to an upper case of a mirror unit tilting mechanism so as to protrude therefrom. A fitting portion is formed on a pivot plate side so as to correspond to the joint portion. The joint portion is formed into a hollow hemisphere shape. A support shaft is provided upright at a center portion of an outer wall, and a spherical portion is formed in the outer wall. The fitting portion has a hollow hemisphere dome shape and includes a spherical side wall portion and a ceiling portion which has a wave shape in cross section. The fitting portion is lightly press-fitted to the joint portion through one-touch insertion operation. The fitting portion and the joint portion are swingably connected to each other under a state in which curved surfaces of the spherical portion and the side wall portion are held in contact with each other.

Abstract: A mirror surface angle adjusting device includes: a pivot plate (10) which supports a mirror (6) and is attached to a holder (9) pivotably three-dimensionally on a pivot shaft (76); a bracket (8) disposed on a vehicle body; a mirror tilting drive section (11) contained between the bracket (8) and the holder (9) attached to the bracket (8); an operation shaft (44A, 44B) of the mirror tilting drive section (11), the operation shaft penetrating through the holder (9) and being connected to the pivot plate (10); a detection rod (101A, 101B) which moves following the pivot plate (10); an angle detection section (100) which detects a tilt angle of the pivot plate (10); a pivot depressed portion (80) into which the pivot shaft can be press-fitted; and a gear positioning rib (69) provided on an inner wall of the holder (9) to position the mirror tilting drive section (42).

Abstract: A joint portion (11) is provided to an upper case (3) of a mirror unit tilting mechanism (1) so as to protrude therefrom. A fitting portion (21) is formed on a pivot plate (5) side so as to correspond to the joint portion (11). The joint portion (11) is formed into a hollow hemisphere shape. A support shaft (13) is provided upright at a center portion of an outer wall (12), and a spherical portion (12b) is formed in the outer wall (12). The fitting portion (21) has a hollow hemisphere dome shape and includes a spherical side wall portion (22) and a ceiling portion (23) which has a wave shape in cross section. The fitting portion (21) is lightly press-fitted to the joint portion (11) through one-touch insertion operation. The fitting portion (21) and the joint portion (11) are swingably connected to each other under a state in which curved surfaces of the spherical portion (12b) and the side wall portion (22) are held in contact with each other.

Abstract: The present invention relates to a lightweight and flexible material for prevention of electric waves having both absorbing properties and shielding properties against electric waves. In the present invention, carbon fiber or magnetic particles, or both and graphitized carbon black are dispersed and incorporated into an insulating substrate so that the weight ratio of the graphitized carbon black to the carbon fiber, the magnetic particles or the sum of the two may be 0.3 to 5.

Abstract: A wave absorber which is light in weight, rich in flexibility and excellent in wave absorption characteristics in a microwave frequency range. The wave absorber in which composite carbon black particles including crystalline graphite and amorphous carbon black are dispersed into an insulating matrix. In the wave absorber, dispersion of the composite carbon black particles is adjusted so that a ratio (.rho./R) of a volume resistivity .rho. measured at frequencies of 30, 100 and 500 kHz to a measured DC volume resistivity R is in a predetermined range and a volume ratio of the composite carbon black particles having particle diameters of 10 nm to 200 nm to all the composite carbon black particles is in a range of 5% to 95%. Thereby, a wave absorber excellent in absorption characteristics is obtained.
