Japanese Unexamined Patent Publication No. 2000-168443 (FIG. 1)

  FIG. 4 to FIG. 6 show such a conventional rear-view automobile rear-view mirror. Reference numeral 1 denotes a box-shaped rear-view rear-view mirror that is attached to the front of an existing rear-view mirror 2 in the car and has a front side opened. The main body 3 is a mirror fixed to the edge of the room mirror body 1 so as to block the front side opening of the room mirror body 1, 4 is a lower jaw projecting to the left and right of the rear lower part of the room mirror body 1, In the upper part of the lower jaw 4, a vertically extending groove 6 is provided in the room mirror main body 1, 6 is a movable piece that can be moved up and down in each groove 5, and 7 is an upper rear surface of each movable piece 6. The upper jaw is provided so as to protrude to the side, 8 is a hook-like claw provided on the front surface of each movable piece 6, 9 is a cylindrical protrusion provided on the center of the front surface of the room mirror body 1, and 10 is For constantly urging the movable piece 6 downward 11 and 11 are looped portions of the spring 10 wound twice in the central portion so that they are fitted to the outer periphery of the protruding portion 9, and 12 are formed from both ends of the looped portion 11 to the top of the claw 8. A hook portion of the spring 10 that extends linearly toward the claw 8 and elastically engages with the claw 8, and a protrusion 13 prevents the loop-like portion 11 of the spring 10 from coming off the protrusion 9. A fixing tool 14, which is crimped to the portion 9, is a cushion material fixed to the surface of the lower jaw 4 with double-sided tape.

  In the conventional retrofit automotive roof mirror described above, if the existing room mirror 2 is sandwiched between the lower jaw 4 and the upper jaw 7 of the room mirror main body 1, the spring 10 can be retrofitted by the elastic force of the spring 10. Can be mounted on the existing room mirror 2.

  Further, the existing room mirror 2 can be stably held by the cushion material 14 provided on the lower jaw 7.

  However, in the conventional automotive rear-view mirror, the loop-shaped portion 11 of the spring 10 is fitted to the protruding portion 9 and then the protruding portion 9 is prevented from coming off as the spring 10 when assembled. Since the fixing tool 13 needs to be caulked, there are disadvantages that the number of manufacturing steps correspondingly increases and the number of parts increases by the amount of the fixing tool 13.

  In addition, since the cushion material 14 is fixed to the lower jaw 4 with the double-sided tape, the number of parts increases by the amount of the double-sided tape. Also, when assembling the rearview mirror, the trouble of removing the cover protecting the adhesive surface of the double-sided tape is required. In addition, during use of the automobile rearview mirror, the cushion material 14 may be peeled off from the lower jaw 4 due to deterioration of the adhesive portion of the double-sided tape due to heat.

  Further, instead of using the fixing tool 13, as shown in FIG. 7, a flange 10 that protrudes outward in the radial direction is provided at the distal end portion of the outer peripheral surface of the protruding portion 9, and the spring 10 fitted to the protruding portion 9. However, when the loop-shaped part 11 of the spring 10 is fitted to the projecting part 9, the inner diameter of the loop-shaped part 11 of the spring 10 is increased. A process is needed and a manufacturing process will increase.

  Accordingly, as shown in FIGS. 8 to 11, instead of providing the protrusion 9 at the center of the front surface of the rearview mirror body 1, a pair of left and right contact portions that contact the outer peripheral surface of the loop-shaped portion 11 of the spring 10 or It is conceivable to provide the contact walls 16, 16 and a loop-shaped part locking flange part 17 that protrudes inward in the radial direction from the tip of each contact wall 16 and covers a part of the end surface of the loop-shaped part 11. It is done.

  When assembling an automobile rear-view mirror having such a configuration, the end surface of the loop-shaped portion 11 of the spring 10 is hidden in the lower surface of the loop-shaped portion retaining flange portion 17 and the outer peripheral surface thereof is When the left and right abutting walls 16 are brought into contact with each other and the left and right hook portions 12 and 12 of the spring 10 are engaged with the hook-like claws 8 of the movable piece 6, the spring 10 is fixed to the rear mirror body 1. In addition, the spring 10 can be prevented from being detached by the loop-shaped part disengagement flange part 17. Instead of providing the pair of left and right contact walls 16, 16, a single contact wall 16 may be used.

  Also, as shown in FIG. 12, a pair of left and right abutting walls 16 and 16 are spaced apart from each other in the circumferential direction, and a protrusion 18 is provided on the front surface of the room mirror body 1 between them, and at the tip of the protrusion 18. The loop-shaped part detachment flange part 17 may be provided.

  Further, as shown in FIG. 13, instead of using the pair of left and right contact walls 16, a semicircular arc-shaped loop-shaped portion contact wall 19 that contacts a part of the outer peripheral surface of the loop-shaped portion 11 of the spring 10 is provided. In addition, a semi-disc-like loop-shaped part detachment flange part 17 may be provided at the tip of the abutting wall 19.

  Further, as shown in FIG. 14, instead of using a pair of left and right contact walls 16, a contact wall 21 that contacts the top 20 of the outer peripheral surface of the loop-shaped portion 11, and both sides of the outer peripheral surface of the loop-shaped portion 11. Protrusions 22 and 22 may be provided on the left and right ends of the left and right protrusions 22 and 22, and a loop-shaped part detachment flange 17 connecting the protrusions 22 and 22 may be provided.

  Further, as shown in FIG. 15, instead of using a pair of left and right contact walls 16 that contact the outer peripheral surface of the loop-shaped portion 11 of the spring 10, contact pins 23 that contact the inner peripheral surface of the loop-shaped portion are provided. It may be provided.

  In this example, at the time of assembly, the loop-shaped portion 11 of the spring 10 is hidden in the lower surface of the loop-shaped portion locking flange portion 17, the contact pin 23 is inserted into the loop-shaped portion 11, and If the left and right hook portions 12, 12 of the spring 10 are engaged with the hook-like claws 8 of the movable piece 6, respectively, the spring 10 can be fixed to the room mirror main body 1 and the spring 10 cannot be removed. It becomes like this.

  Further, as shown in FIGS. 16 and 17, a step portion 24 extending in the horizontal direction provided on the left and right of the rear lower portion of the rearview mirror main body 1, an elastic member 25 extending upward provided on the step portion 24, and A card holding portion 27 including a protrusion 26 provided so as to protrude toward the room mirror main body is provided on the upper portion of the elastic member 25, and two vertically extending step portions are provided at the center of the rear surface of the room mirror main body 1. 28 may be provided.

  According to this example, a card such as a highway card can be held between the protrusion 26 of the elastic member 25 and the rear surface of the rearview mirror main body 1.

  In addition, since the step portion 28 is provided, it is possible to prevent the card inserted from the side face from entering more than necessary and the card from being pulled out from the side face of the rearview mirror.

  Note that the card holding portion 27 may be provided only on one of the left and right sides of the room mirror body.

  Also, as shown in FIGS. 18 and 19, the card holding portion 27 is covered with a cover 29, and a groove 29 'for inserting a card is provided on the side of the cover 29 so that the inserted card can be seen from the outside. Also good.

  The cover 29 may be detachable.

  Moreover, you may provide the card storage box (not shown) which each covers the right and left of the back side of the said room mirror main body, without providing the card clamping part 27. FIG.

  In this example, a card such as a highway card can be stored in the card storage box.
