The present invention provides a bolting structure for a magnesium alloy member, having a non-magnesium alloy and conventional member 12 disposed on the magnesium alloy member 15, the magnesium alloy member 15 being covered with an insulator 14, and a bolt 18 initially inserted through the magnesium alloy member 15 and then into the conventional member 12, thereby permitting the conventional member 12 and the magnesium alloy member 15 to be bolted together, comprising: a washer 17 disposed between a head 18 a of the bolt 18 and the magnesium alloy member 15, the washer 17 having a boss 16 disposed thereon, wherein the magnesium alloy member 15 is formed with a through-hole 13 that is greater in diameter than a bolthole 19 of the washer 17. The above boss 16 and through-hole 13 eliminate a chance that the bolt 18 contacts the through-hole 13. The insulator 14 remains intact because of non-contact of the bolt 18 with the through-hole 13 so that no stray current corrosion occurs.

PROBLEM TO BE SOLVED: To provide a capacitor capable of reducing a noisemaking phenomenon fully. SOLUTION: The capacitor comprises a capacitor body section 10 in a rectangular parallelepiped shape, where internal electrodes 11, 12 are laminated alternately via a dielectric layer 13; and a pair of external electrodes 21, 22 connected to each of the internal electrodes 11, 12 electrically. Respective external electrodes 21, 22 are provided on a pair of maximum width end faces opposing each other in the capacitor body section 10 so that the pair of minimum width end faces opposing each other in the capacitor body section 10 becomes a free end.

PROBLEM TO BE SOLVED: To provide a light distribution control system which can realize suitable light distribution in each of a plurality of express highways having different limiting speeds and can reduce uncomfortable feeling of a driver in switching between light distribution for passing each other and for high-speed travel. SOLUTION: The light distribution control system 1 comprises a control circuit 4 which controls the light distribution pattern of the headlight 3 of the vehicle to switch between the light distribution for passing each other and for high-speed travel, a vehicle speed detecting device 5 for detecting the vehicle speed, and a headlight control circuit 6 for adjusting the light quantity of the headlight 3. When the vehicle speed detecting device 5 determines that the vehicle speed becomes a predetermined speed V 1 or higher, the control circuit 4 switches the light distribution for passing each other to the light distribution for high-speed travel. When the vehicle speed detecting device 5 determines that the vehicle speed becomes a second predetermined speed V 2 or higher different from the first predetermined speed, the headlight control circuit 6 increases the light quantity of the headlight 3.
