The inner wall 12b and the inner wall 12a are separately provided in the space between them to pass electrical wiring to a mirror unit (not shown). However, the inner wall 12b and the inner wall 12a can also function as a single wall to regulate the position of the slide support 4. it is obvious.

  The rib 9 and the outer edge portion 23 form an inner wall that defines a hollow portion provided inside the sun visor body 1. The slide support 4 attached to the end portion of the shaft 2 is slidably disposed in the hollow portion, and the resin core members 6 and 7 are folded around the hinge 17 to be included in the sun visor body 1. . The shaft 2 is rotatably attached to the vehicle body panel at the other end, and the sun visor body 1 slides along the shaft 2 (see FIG. 1). At this time, the slide support 4 moves inside the hollow portion along the rib 9 that functions as a slide guide.

  When the sun visor body 1 slides in the direction of expansion along the shaft 2, the slide support 4 attached to the end of the shaft 2 may slide to a position where it abuts on the inner wall 15 that is the second lock portion. it can. On the other hand, when sliding in the direction in which the shaft 2 is housed inside the sun visor body 1, the slide support 4 can slide to a position where it abuts against the inner walls 12a and 12b, which are the first lock portions.

  The slide support 4 is provided with a protruding portion 16a on the side surface through which the shaft 2 passes, and provided with protruding portions 13a and 14a on the opposite side surface. The protrusion 16 a engages with an engagement hole 16 b provided in the inner wall 15 when the sun visor body 1 slides in the expansion direction and the slide support 4 comes into contact with the inner wall 15. On the other hand, the protrusions 13a and 14a engage with the engagement holes 13b and 14b provided in the inner walls 12a and 12b when the sun visor body 1 slides in the storing direction and the slide support 4 comes into contact with the inner walls 12a and 12b. To do.

  The slide support 4 has a configuration in which a U-shaped main body 11 and a spring member 10 are combined and attached to the end of the shaft 2. The slide support body 11 is mounted so as to be rotatable about the shaft 2. Thereby, the sun visor main body supported by the slide support 4 can also rotate around the shaft 2 as an axis. Further, the spring member 10 has a function of biasing the shaft 2 by an elastic force and holding the sun visor body 1 at an arbitrary rotation position.

  As described above, the slide support 4 supports the sun visor body 1 and slides along the shaft 2, and also has a function of rotating the sun visor body 1 around the shaft 2, and exhibits the function of a sliding sun visor. It can be said that it is a key member for making it.

  FIG. 4 is a schematic diagram showing a state in which the slide support 4 abuts against the inner wall 15 when the sun visor body 1 slides in the extending direction. The shaft 2 is pulled out according to the slide of the sun visor body 1, and the side surface of the slide support 4 through which the shaft 2 penetrates comes into contact with the inner wall 15. At this time, the protrusion 16 a provided on the side surface of the slide support 4 engages with the engagement hole 16 b provided in the inner wall 15. By this engagement, the sun visor body 1 is held by the slide support 4 and the posture with respect to the shaft 2 is stabilized.

  4 shows the inner wall 15 provided on the resin core material 7 side, the corresponding inner wall is also provided on the resin core material 6 side, and the resin core materials 6 and 7 are folded. In this case, both inner walls come into contact with each other to form a second lock portion. Although the number of protrusions shown in the drawing is one, a plurality of protrusions may be provided, and a plurality of corresponding engagement holes may be provided in the inner wall 15. In this case, the plurality of engagement holes are preferably provided on either one of the resin core materials. This is because there may be a case where the resin core materials 6 and 7 cannot be engaged with a plurality of protrusions provided on the slide support 4 due to a positional shift when the resin core materials 6 and 7 are overlapped.

  FIG. 5 is a schematic diagram showing a state in which the slide support 4 comes into contact with the inner walls 12a and 12b when the shaft 2 is slid in the direction in which the shaft 2 is housed in the sun visor body 1. The two protrusions 13a and 14a provided on the side surface of the slide support 4 engage with the engagement holes 13b provided on the inner wall 12a and the engagement holes 14b provided on the inner wall 12b, and the sun visor body 1 is slid. 4 is held. Even in this case, as described above, the engagement holes 13b and 14b are preferably provided on the same resin core side.

  As described above, the lock mechanism is configured by the combination of the protrusion provided on the slide support and the engagement hole provided on the inner wall. The number of the lock mechanisms provided is the number shown in the above embodiment. Needless to say, it is not limited, and is appropriately set depending on the shape of the sun visor body.

  FIG. 6 is a perspective view schematically showing the slide support main body 11. The slide support body 11 has a U shape with a mounting portion for the spring member 10 interposed therebetween. An opening 2b for inserting the shaft 2 is provided through the side surface. Further, protrusions 13a and 14a, 16a are provided on the side surfaces on both sides. The tip of each protrusion is processed into a tapered shape T so that engagement with the engagement holes 13b, 14b, and 16b provided in the first and second lock portions is facilitated.

  The shape of the protrusion in the drawing is a square, but is not limited to this, and may be an arbitrary shape such as a circle or a polygon. In addition, the protrusion and the engagement hole may be engageable / removable, but can be detachable. That is, the sun visor body can be locked to the slide support 4 by designing the size of the protrusion and the engagement hole in a range having a suitable insertion resistance. As a result, the sun visor body can be fixed at both ends of the slidable range, that is, at the position where the slide is maximized in the expansion direction and at the position where the shaft 2 is completely housed in the body, thereby improving convenience. Can do.

  Further, in order for the sun visor body 1 to slide smoothly along the shaft 2, the slide support 4 is slidable in the hollow portion surrounded by the resin cores 6 and 7 and the rib 9 which is a slide guide. In addition, it is preferably held with a gap that does not move in a direction perpendicular to the sliding direction (see FIG. 2). Further, assuming a case where the sun visor body 1 is set to a desired position along the shaft 2 and used, the slide support 4 is mounted so as to have a sliding resistance that does not cause displacement due to vibration of the vehicle. The

  However, even if the slide support 4 is a sun visor arranged so as to have the above characteristics in the hollow portion surrounded by the resin cores 6 and 7 and the rib 9, the passenger compartment becomes hot. When the temperature of the sun visor body rises and the resin cores 6 and 7 expand, the sliding resistance of the slide support 4 decreases, and the sun visor body 1 slides due to slight vibration.

  In the slide type sun visor according to the present invention, as described above, at least at the position where the slide is longest in the expansion direction or the position where the slide sunvisor is stored shortest, the protrusion 16a or the protrusion 13a provided on the slide support 4 is provided. 14a engages with the engagement hole 16b or the engagement holes 13b and 14b to stably hold the sun visor body, so that the function of the sliding sun visor is not lost even in a high temperature environment.
