Further, as shown in FIG. 2, when the sun visor main body 11 is stored on the roof trim 60 side and when the sun visor main body 11 is tilted in front of the front window, the outer peripheral surface 21b of the cylindrical end portion 21 is formed. The pair of arc plate-shaped contact portions 29, 29 provided come into contact (conductivity) with the contact portion 53 of each spring portion 52 of the pair of terminals 50, 50 for power supply, and are energized (ON). That is, the conductive circuit connecting the pair of conductors 28, 28 arranged in the arm 20 and the lighting lamp 13 of the sun visor main body 11 is energized, so that the lighting ready state of the lighting lamp 13 of the sun visor main body 11 is set. When the cover (slide member) 14 formed and covering the vanity mirror 12 of the sun visor main body 11 is slid open, a switch mechanism (not shown) is turned on and the illumination lamp 13 is turned on. Further, when the sun visor main body 11 is tilted to the side of the side window, the pair of arc plate-shaped contact portions 29 and 29 on the outer peripheral surface 21b of the cylindrical end portion 21 are springs of the pair of terminals 50 and 50 for power supply. The conductive circuit of the illumination lamp 13 is in a non-energized (OFF) state because it is separated from the contact portion 53 of the portion 52 and becomes non-conducting.

According to the vehicle sun visor 10 of the above embodiment, when assembling the vehicle sun visor 10, first, as shown in FIG. 3, a circular inner circumference formed diagonally on the arm support portion 31 of the mounting bracket 30. The cylindrical end 21 side of the arm 20 is press-fitted into the surface 31a. As a result of this press-fitting, as shown in FIG. 5, the locking projection 32 protruding from the inner peripheral surface 31a of the arm support portion 31 enters the annular concave engaging groove 25 of the arm 20 and enters the annular flange portion 24. By engaging, the cylindrical end 21 of the arm 20 is rotatably supported by the arm support 31.

Next, as shown in FIG. 4, after inserting the pair of terminals 50, 50 into the housing 41 of the connector 40, as shown in FIG. 5, the arm 20 exposed to the outside from the arm support portion 31 of the mounting bracket 30. FIG. 6 shows a pair of arcuate concave grooves 22 and 22 for storing lubricating oil (also used for assembling the connector) of the cylindrical end portion 21 of the connector 40 at positions facing each other of the side walls 43 and 43 of the connector 40. As shown in the above, a pair of engagement holes 36, 36 provided in the recess 35 for assembling the connector on the upper surface 30a of the mounting bracket 30, and a pair of engagement holes provided on both side walls 43, 43 of the housing 41 of the connector 40. Insert the stop pieces 43b and 43b, rotate the connector 40 as shown by the arrow in FIG. 6, and lock the locking piece of the housing body 42 of the connector 40 into the locking claw 37 of the recess 35 for assembling the connector. The connector 40 is assembled to the upper surface 30a of the mounting bracket 30 by locking the portion 42a.

At this time, as shown in FIG. 8B, each contact portion 53 of the pair of terminals 50, 50 assembled to the connector 40 is used for storing lubricating oil on the outer peripheral surface 21b of the cylindrical end portion 21 of the arm 20. Assembling the connector 40 to the mounting bracket 30 through the pair of arcuate concave grooves 22 and 22 without contacting the pair of arcuate plate-shaped contact portions 29 and 29 on the outer peripheral surface 21b of the cylindrical end portion 21. Can be done. Therefore, the pair of arc plate-shaped contact portions 29, 29 and the contact portion 53 of each spring portion 52 of the pair of terminals 50, 50 do not interfere with each other, and the spring portions 52 of the pair of terminals 50, 50 are deformed. Can be prevented. The paste-like grease G is filled in the groove 22 for storing the lubricating oil before or after assembling the mounting bracket 30 and the connector 40.

Further, as shown in FIGS. 8A and 8B, before the arm 20 is rotated, the contact portions 53 of the pair of terminals 50 and 50 of the connector 40 are the outer peripheral surfaces of the cylindrical end portion 21 of the arm 20. By entering the gaps S of the pair of arc plate-shaped contact portions 29 and 29 provided in 21b, the conductive circuit is in a non-energized (OFF) state and is provided on the outer peripheral surface 21b of the cylindrical end portion 21. The paste-like grease G contained in the pair of arcuate concave groove portions 22 and 22 for storing the lubricating oil adheres to the contact portions 53 of the pair of terminals 50 and 50. When the conductive circuit of the illumination lamp 13 is in a non-energized state, the contact portion 53 of the terminal 50 comes to the position of the arcuate concave groove portion 22 for storing the lubricating oil in the cylindrical end portion 21, so that the grease G is always present in the contact portion 53. Be supplied.

Then, as shown in FIG. 9A, when the arm 20 is rotated, the contact portions 53 of the pair of terminals 50 and 50 of the connector 40 are provided on the outer peripheral surface 21b of the cylindrical end portion 21 of the arm 20. The conductive circuit of the illumination lamp 13 is energized (ON) in contact with the pair of arc plate-shaped contact portions 29, 29. At this time, the supplied grease G can protect the contact portions 29 and 53 from wear due to sliding.

Even if the rotation of the arm 20 shown in FIGS. 8 (a) and 9 (a) is repeated, grease G is always applied to the contact portion 53 of the terminal 50 when the conductive circuit of the illumination lamp 13 is in a non-energized state. Since it adheres, the grease G is not lost due to sliding, and the grease G is always supplied to the contact portion 53, so that sliding wear between the contact portions 29 and 53 can be reliably suppressed. By suppressing sliding wear between the contact portions 29 and 53, a pair of arc plate-shaped contact portions 29 and 29 provided on the outer peripheral surface 21b of the cylindrical end portion 21 of the arm 20 and a pair for power supply of the connector 40 are supplied. The contact reliability of the terminals 50 and 50 with each contact portion 53 can always be maintained.

According to the above embodiment, the sun visor main body is provided with an illumination lamp as an electrical component, but the sun visor main body may be provided with a small and thin liquid crystal monitor or the like as an electrical component.
