  On the other hand, the mirror base 3 is comprised by the vehicle attachment piece 3a and the housing support part 3b. The vehicle mounting piece 3a and the housing support portion 3b are integrally formed of resin.

  The vehicle attachment piece 3a is formed in a substantially trapezoidal plate shape corresponding to the shape of a gusset plate (not shown) disposed on the door portion of the vehicle. A packing 3c having substantially the same shape as the vehicle mounting piece 3a is fitted into the vehicle mounting piece 3a. Thereby, the airtightness and watertightness between the mirror base 3 and the gusset plate are maintained.

  The housing support portion 3b has a substantially rectangular parallelepiped shape and is formed so as to protrude in the horizontal direction from the lower portion of the side surface of the vehicle attachment piece 3a. A shaft receiving portion 3d is provided on the upper surface of the housing support portion 3b. The lower end portion of the shaft 31 protruding from the shaft insertion hole 22 is fixed to the shaft receiving portion 3d by bolting or the like. Thereby, the housing 2 can be rotated with respect to the mirror base 3 around the shaft 31.

  By this rotation, the vehicle outer mirror 1 can take three states: a use state, a retracted state, and a retracted state. The use state is a state in which the vehicle outer mirror 1 protrudes to the side of the vehicle. The retracted state is a state in which the vehicle outer mirror 1 is folded toward the vehicle rear side. The retracted state is a state that can be taken, for example, when a person or the like collides with the vehicle outer mirror 1, and is a state in which the vehicle outer mirror 1 is tilted forward or backward in order to reduce the impact. . And the rotation range of the housing 2 when each of these states shifts is regulated by a stopper (not shown) provided on the mirror base 3.

  On the other hand, as shown in FIG. 3, the vehicle outer mirror 1 according to the present embodiment has a characteristic structure for assembling the frame 8 to the housing 2. In FIG. 3, the front side of the housing 2 is shown, while the back side of the frame 8 is shown. As a structure thereof, as shown in FIGS. 3 and 4, the frame 8 is formed with a first screw insertion hole 41 serving as a first fixing portion and a second screw insertion hole 42 serving as a second fixing portion.

  The first screw insertion hole 41 is formed in a direction protruding from the front side to the back side of the frame 8, and the second screw insertion hole 42 is in the direction in which the first screw insertion hole 41 is formed. It is an orthogonal direction, and is formed with a slight thickness in the vertical direction with the vehicle outer mirror 1 attached to the vehicle.

  Moreover, the 1st latching member 43 and the 2nd latching member 44 are provided in the other side through the axis line which connects these 1st screw insertion holes 41 and the 2nd screw insertion holes 42, respectively. These latch members 43 and 44 are arranged at positions that are symmetric (line symmetric) about the axis. The first hooking member 43 and the second hooking member 44 have the same structure as each other, and each includes a trunk portion attached to the frame 8 and a flange portion formed at the tip of the trunk portion.

  Further, a hoof-like protrusion 45 serving as a movement restricting portion of the present invention is formed around the first screw insertion hole 41. The hoof-like projection 45 is formed so as to surround a range of about 180 degrees below the inner side around the first screw insertion hole 41, and the screw insertion hole is formed in the opening of the hoof-like projection 45. ing.

  By forming the movement restricting portion with such a hoof-like protrusion, a movement restricting portion having a simple shape can be obtained. In addition, the hoof-like protrusion 45 is formed around the first screw insertion hole 41. For this reason, since it is not necessary to provide a separate space for providing the movement restricting portion, a large space for arranging other members can be secured.

  In addition, the hoof-like protrusion 45 is tapered from the side where the first screw insertion hole 41 is formed toward the inner lower side. Therefore, the side facing the first screw insertion hole 41 protrudes to a certain extent on the back side, and the protruding portion gently disappears at the inner lower position.

  On the other hand, as shown in FIGS. 3 and 5, the housing 2 is provided with a boss 51 serving as a first fixed portion and a screw hole 52 serving as a second fixed portion. A first hooked hole 53 and a second hooked hole 54 serving as a second hooked portion are formed. When the frame 8 is assembled to the housing 2, the boss 51 and the screw hole 52 are arranged at positions corresponding to the first screw insertion hole 41 and the second screw insertion hole 42, respectively. Further, the first hooking hole 53 and the second hooking hole 54 are disposed at positions corresponding to the first hooking member 43 and the second hooking member 44, respectively.

  The boss 51 is formed with a screw hole into which a screw is screwed, and the screw inserted into the first screw insertion hole 41 is screwed into the screw hole formed in the boss 51 from the front side toward the back side. Thus, the frame 8 is fixed to the housing 2. Further, the screw hole 52 is formed in the vertical direction with the vehicle outer mirror 1 attached to the vehicle, and the screw inserted into the second screw insertion hole 42 is inserted into the screw hole 52. Thus, the frame 8 is fixed to the housing 2.

  Further, the first hooking hole 53 and the second hooking hole 54 have the same shape as each other, and when viewed from the front side, the substantially pentagonal part and the elongated part are connected. It has a different shape. The substantially pentagonal portion has two corners that form a substantially right angle, and has a second side and a third side that extend substantially at right angles from both ends of the first side that connect the corners. From the other end of each of the second side and the third side, the fourth side and the fifth side extend in a direction facing each other, and the fourth side and the fifth side intersect at one point. A shape is formed. The elongated portion is connected to the portion where the fourth side and the fifth side intersect.

  The substantially pentagonal portion of the first hooked hole 53 and the second hooked hole 54 is arranged on the outer upper side of the housing 2 and the elongated part is arranged on the inner lower side. The elongated portions have substantially the same width as the distal ends of the trunk portions of the first and second retaining members 43 and 44, respectively, and the distal ends of the trunk portions of the retaining members 43 and 44 are inserted into the elongated portions. As a result, the hooks of the hooking members 43 and 44 are hooked to the elongated portions of the hooked holes 53 and 54.

  A procedure for assembling the housing 2 and the frame 8 in the vehicle outer mirror according to the present embodiment having the above-described configuration will be described.

  In the vehicle outer mirror 1 according to the present embodiment, when the frame 8 is assembled to the housing 2, the frame 8 is first accommodated in the housing 2. In this state, the frame 8 has not yet been assembled to the housing 2. Next, when viewed from the front side of the housing 2, the screw insertion holes 41 and 42 and the latching members 43 and 44 in the frame 8 are respectively connected to the boss 51, the screw hole 52, and the latched holes 53 and 54 in the housing 2. On the other hand, it is arranged at a position slightly above the left side and a position slightly before the position where the housing 2 is assembled.

  From this state, the frame 8 is slid in the lower right direction, which is a direction along the axis connecting the screw insertion holes 41 and 42, while pushing the frame 8 in the direction (backward) of the housing 2. Then, as schematically shown in FIG. 6, the body portions and the flange portions of the retaining members 43 and 44 in the frame 8 are inserted into the substantially pentagonal portions of the retaining holes 53 and 54 in the housing 2, respectively. In FIG. 6, the state before the slide is indicated by a solid line, and the state after the slide is indicated by an imaginary line. Here, since the substantially pentagonal portion has a larger area than the elongated portion, the latching members 43 and 44 are easily inserted into the latched holes 53 and 54.

  When the latch members 43 and 44 in the frame 8 are inserted into the substantially pentagonal portions of the latch holes 53 and 54 in the housing 2, the frame 8 is further slid in the lower right direction with respect to the housing 2. Then, the latching members 43 and 44 in the frame 8 are guided to the elongated portions formed in the latching holes 53 and 54 of the housing 2, and the front ends and the flanges of the latching members 43 and 44 are hooked as they are. It enters into the elongated portions of the stop holes 53 and 54.

  At this time, the hoof-like protrusion 45 formed on the frame 8 gets over the boss 51 provided on the housing 2. Here, the hoof-like projection 45 has a side that faces the first screw insertion hole 41 protrudes to a certain extent on the back side, and the protruding portion gently disappears at the inner lower position. For this reason, when the hoof-like protrusion 45 gets over the boss 51, first, the hoof-like protrusion 45 starts to get over the boss 51 from the disappeared portion of the protruding portion, and the hoof-like protrusion 45 gets over the boss 51 in accordance with the taper inclination. . Therefore, the hoof-like protrusion 45 can smoothly get over the boss 51.

  Eventually, when the latching members 43, 44 enter the elongated portions of the latching holes 53, 54, the hoof-like projection 45 gets over the boss 51. At this time, the elongate portions of the hooking holes 53 and 54 are in a state where the hooks of the hooking members 43 and 44 are hooked. Thus, the frame 8 is fixed to the housing 2 by the latch members 43 and 44 being latched by the latch holes 53 and 54. Thus, the frame 8 can be hooked on the housing 2 only by moving the frame 8 in the direction along the axis connecting the screw insertion holes 41 and 42 with respect to the housing 2. Therefore, the frame 8 can be assembled to the housing 2 in one step of moving the frame 8 relative to the housing 2. Further, since the latch members 43 and 44 are arranged at positions symmetrical to each other with respect to the axis line connecting the screw insertion holes 41 and 42, the rotational displacement of the housing 2 with respect to the frame 8 can be restricted.

  On the other hand, in the hoof-like protrusion 45 that has passed over the boss 51, the protruding portion on the outer side is in contact with the side surface of the boss 51. In this way, when the hoof-like projection 45 abuts on the boss 51, it is possible to prevent the frame 8 from coming off the housing 2 in the direction opposite to the sliding direction. Accordingly, it is possible to prevent a situation where the frame assembled to the housing is easily detached.

  Thus, when the frame 8 is hooked on the housing 2, the screw insertion holes 41 and 42 in the frame 8 are disposed at positions corresponding to the bosses 51 and the screw holes 52 in the housing 2, respectively. Thereafter, the frame 8 is fixed to the housing 2 by screwing screws into the screw holes and the screw holes 52 formed in the boss 51.

  Thus, the fixing of the frame 8 to the housing 2 is completed.

  Thus, in the vehicle outer mirror according to the present embodiment, the frame 8 can be assembled to the housing 2 in one step of moving the frame 8 relative to the housing 2. Further, it is possible to prevent a situation in which the frame attached to the housing is easily detached.
