It is formed. Then, the sun visor body 2 is configured to be pivotable between the storage position in which the sun visor main body 2 is brought close to the roof and the use position for blocking sunlight from the windshield entering the passenger's eyes, using the horizontal shaft 4A as a fulcrum. The sun visor body 2 can be turned to the side window side of the vehicle with the longitudinal axis 4B as a fulcrum by removing the collar 6 from the hook (shown by a two-dot chain line in FIG. 1). .

  Therefore, when the sun visor body 2 is turned to the side window side of the vehicle from the use position described above, it is possible to block the sunlight from the side glass which the passenger sees. In this case, the sun visor main body 2 can be moved along the stay 4 in the longitudinal direction, that is, in the longitudinal direction of the vehicle (a state of moving in the forward direction is shown in FIG. By moving the sun visor body 2 to an appropriate position for the passenger, it is possible to reliably block the sunlight from the side glass that enters the passenger's eyes.

  That is, although the sun visor main body 2 is rotatably mounted around the long axis of the horizontal shaft portion 4A of the stay 4 and movably (slidable) in the long axis direction, the rotation is possible. The structure which makes it possible to move and move will be described later.

  First, as shown in FIGS. 2 and 3, the sun visor main body 2 is provided with a first structure 2A and a second structure 2B which are connected via the connection portion 4 and also divided into two. . And these 1st and 2nd structures 2A and 2B face each other's inside, are piled up, and are joined. In this case, when the first structure 2A and the second structure 2B are superimposed, a hollow internal space is formed.

  Then, on the surface of the first structure 2A facing the second structure 2B, a first contact portion 11A is erected toward the opposite side along the peripheral edge portion. On the opposing surface located inside the first contact portion 11A, a large number of reinforcing ribs 12A for improving the strength, and a connection for combining the first structure 2A and the second structure 2B. The cylindrical portion 13A is formed.

  Further, on the surface of the second structure 2B facing the first structure 2A, a second contact portion 11B is erected toward the opposite side along the periphery of the second structure 2B. A plurality of reinforcing ribs 12B for improving the strength and the first structural body 2A and the second structural body 2B are combined on an opposing surface located inside the second contact portion 11B. A connecting shaft 13B is formed, which is press-fitted into the groove of the connecting cylindrical portion 13A.

  Thereby, in a state where the first and second contact portions 11A and 11B are brought into contact with each other and the connection shaft portion 13B is press-fit into the connection cylindrical portion 13A, the first structure 2A and the second structure It is fixed to 2B.

  A guide rod 8 serving as a guide body for holding the stay 4 into which the lateral shaft 4A is inserted and guiding the movement of the movable body 7 described later is slidably inserted in one of the main body constituting bodies 2A. The movable body 7 is attached. Therefore, the movable body 7 is configured to be relatively slidable (slidable) in the longitudinal direction of the sun visor body along the guide rod 8. The guide rod 8 is, for example, a round rod having a circular cross section made of metal such as steel, and extends horizontally along the upper edge of the sun visor body 2. The cross-sectional shape of the guide rod 8 is not limited to the circular shape shown in the present embodiment, and may be triangular, rectangular or any other polygonal shape.

  Here, the movable body 7 will be described. First, the movable body 7 is provided with a bearing member 14 (see FIG. 7) which contacts the circumference of the horizontal axis 4A with a predetermined frictional force so as to be rotatable around the circumference of the stay 4 The holding portion 15 for holding the stay 4 in a state in which the end portion of the portion 4A is inserted into the insertion hole 15A opened in one side surface, and the locking portions 2A1 and 2A1 of the first structure 2A An insertion hole through which the guide rod 8 whose ends are fitted and fixed in the locking grooves 2A2 and 2A2 can slide so as to slide (the cross-sectional shape of the guide rod 8 matches the cross-sectional shape of the guide rod 8) 16A, 16A are formed respectively, and a pair of supports 16 formed so as to face the lower part of the holder 15, the holder 15 and a pair of supports between the pair of supports 16, 16 Form a space S with the parts 16 and 16 Together with the guide rod 8 located in the space S sliding in the insertion holes 16A and 16A of the support portions 16 and 16 from the lower surface to press and bias the holding portion 15 in the direction of the pressing portion 17 ( And a biasing portion).

  The holding unit is configured such that the central portion (of the surface facing the holding unit) in the pair of support units 16 and 16 among the surfaces facing the holding unit is closest to the holding unit 15. It is warped so as to be gradually closer in the 15 direction, and a reinforcing piece 17A is formed to descend downward to reinforce weakening due to the warp.

  Then, as described above, the collar 5 is removed from the hook and the sun visor body 2 is pivoted to the side window side of the vehicle with the longitudinal axis portion 4B as a fulcrum, and then the sun visor body 2 along the stay 4 In the space S of the guide rods 8 sliding in the insertion holes 16A and 16A of the support portions 16 and 16 along the longitudinal direction of the sun visor body when moving the vehicle in the front and rear direction of the vehicle Since the pressing portion 17 is pressed and urged in the direction of the holding portion 15 by line contact with the portion located at the position of the sun visor body 2, the rattling of the sun visor body 2 accompanying the movement can be further suppressed. The stability of the movement operation can be obtained by the biasing force.

  The movable body 7 is composed of the holding portion 15, the pair of support portions 16 and 16, and the pressing portion 17, and the movable body 7 is excellent in slidability, sliding property, abrasion resistance and the like. It is integrally molded of a material, for example, a hard synthetic resin material such as polyacetal (POM), but may be separately formed. Thereby, even if the pressing portion 17 contacts and presses the guide rod 8, the movable body 7 can slide with an appropriate resistance. Further, a lubricant may be applied around the insertion holes 16A, 16A, and the relative movement (sliding) of the guide rod 8 and the insertion holes 16A, 16A can be made smooth by this application. .

  When the passenger grips the sun visor body 2 and moves it along the stay 4 in the longitudinal direction of the vehicle, the movable body 7 is restricted in the vertical direction and the horizontal direction in the sun visor body 2. It will move while.

  That is, as shown in FIG. 2, FIG. 4 and FIG. 8, a plurality of convex portions 18 are formed so as to protrude outward on both side surfaces of the movable body 7, and these convex portions 18 When the horizontal direction of the movable body 7 is restricted by being disposed facing the inner side surface of the second structure 2B. Further, the downward direction is restricted by a support piece 20 in which a convex portion 19 on the bottom surface of the movable body 7 is protruded inward on the inner side surface of the first structure 2A, and similarly, the first structure 2A and the second structure The upward direction is restricted by the restriction piece 21 protruding inward on the inner side surface of the body 2B. Therefore, if the movable body 7 is restricted in the horizontal direction and the vertical direction, it moves along the guide rod 8 and the sun visor body 2 moves in the longitudinal direction of the vehicle along the stay 4.

  By configuring the movable body 7 as described above, the structure is simple as compared with the conventional structure in which the friction mechanism and the coil spring other than the movable body are configured as the friction mechanism, and each supporting portion 16 The guide rods 8 are simply inserted into the 16 insertion holes 16A and 16A, and the installation is also easy.

  Next, the assembly of the vehicle sun visor 1 will be briefly described from the state where the sun visor main body 2 in a state in which the skin 3 is wound is opened. First, the bearing member 14, which rotatably contacts the stay with a predetermined frictional force around the stay 4, is incorporated into the movable body 7.

  Then, the other end portion of the stay 4 in a state where the fixture 5 for rotatably supporting the stay 4 is attached to one end is inserted into the insertion hole 15A of the movable body 7 (see FIG. 6) . Then, the bearing member 14 comes in contact with the tip of the stay 4 around the stay 4 with a predetermined frictional force by being inserted, and the stay 4 has an appropriate holding force by the bearing member 14. It is rotatably supported while being held.

  Then, as described above, in a state where the guide rod 8 and the stay 4 are inserted into the movable body 7 (see FIG. 6), the movable body 7 is accommodated in the first structure 2A. In this case, in the grooves 11A1 and 11B1 formed in the first and second contact portions 11A and 11B of the first and second components 2A and 2B near the fixture 5, and in the reinforcing ribs 12A and 12B The ends 4 of the guide rods 8 are received and fitted in the grooves 10A and 10B, and the end portions of the guide rods 8 inserted in the insertion holes 16A and 16A of the support portions 16 of the movable body 7 are used. The movable body 7 is fitted in the locking grooves 2A2 and 2A2 formed in the locking portions 2A1 and 2A1 of the first structure 2A, and the movable body 7 is accommodated in the first structure 2A.

  Subsequently, the first and second contact portions 11A and 11B of the first and second components 2A and 2B are brought into contact with each other, and the connection shaft portions 13B are pressed into the connection cylindrical portions 13A. Then, the first structure 2A and the second structure 2B are closed.

  Finally, the collar 6 is attached to an opening formed at the upper end of the sun visor body 2 in which the first structure 2A and the second structure 2B are closed. Thus, the assembled vehicle sun visor 1 is attached to the vehicle by fixing the attachment 5 to a panel (not shown) fixed to the vehicle body of the vehicle. Then, the collar 6 is engaged with the hook so that the sun visor main body can be brought close to the roof with the lateral axis 4A of the stay 4 as a fulcrum.

  Then, when driving the vehicle and want to awn, the sun visor main body 2 is rotated in the direction of the windshield with the horizontal axis 4A of the stay 4 as a fulcrum, and the windshield can be seen from the passenger's eyes It can be moved to the use position to block the sunlight. Further, in order to block sunlight from the side window side of the vehicle, the sun visor body 2 can be turned to the side window side of the vehicle with the collar 6 removed from the hook and the longitudinal axis 4B as a fulcrum (Indicated by a two-dot chain line in FIG. 1).

  Furthermore, after turning the sun visor body 2 to the side window side of the vehicle, the sun visor body 2 is moved along the stay 4 in the longitudinal direction, that is, the front and back direction of the vehicle. By moving the sun visor main body 2 to the proper position, it is possible to surely block the sunlight from the side glass which enters the eyes of the passenger.

  In this case, when the sun visor main body 2 is moved in the longitudinal direction of the vehicle along the stay 4, the guide bar 8 slides in the insertion holes 16A, 16A of the support portions 16, 16. Among them, since the pressing portion 17 is pressed and urged in the direction of the holding portion 15 by line contact with a portion located in the space S, the rattling of the sun visor body 2 due to the movement described above is further suppressed Therefore, the stability of the moving operation can be obtained by an appropriate pressing force.
