Next, the action of the beauty device 1 will be described.
When assembling the beauty device 1, first, the power supply unit 300 is stored in the storage unit 113 from the front side of the base member 110, and the lens 150 is attached. Specifically, the power supply unit 300 is housed in the housing part 113 that opens on the front surface of the base member 110 . At this time, the boss 302A of the terminal pressing member 302 is inserted into the concave portion 113B of the bottom wall of the storage portion 113. As shown in FIG. Then, the first packing P<b>1 is fitted into the groove portion 114 on the periphery of the opening of the storage portion 113 . Also, a double-sided tape 156 is attached to the back side of the curved portion 151C of the lens 150 (or the side of the base member 110). In this state, the flat plate portion 151A of the lens 150 is placed on the flat surface 113A, and the engaging convex portions 152 provided on the flat plate portion 151A are engaged with the engaging concave portions 111A and provided on the curved portion 151C. The fitting protrusions 153 are engaged with the engagement recesses 111B (see FIGS. 6 and 15). Then, the fixing members F1 are inserted into the through holes T1 of the engaging convex portion 152 and the flange portion 154 to engage with the engaging holes L1 of the base member 110. As shown in FIG.

As a result, with the first packing P1 interposed between itself and the base member 110, the lens 150 fixed to a plurality of (five in FIG. 5) fixing members F1, which are screws, liquid-tightly seals the opening of the housing portion 113. is sealed to In addition, since the lens 150 is firmly fixed to the flat surface 113A by the fixing member F1, which is a screw, while pressing the first packing P1, the opening of the storage section 113 is reliably waterproofed. Also, the power supply unit 300 is configured to have a photovoltaic panel 301 . Since the photovoltaic panel 301 generates electricity by light passing through the lens 150, unlike a battery or the like, it does not need to be replaced for charging or the like. Therefore, the waterproof property in the housing portion 113 secured at the time of initial assembly is maintained.
In addition, in the assembly of the beauty device 1, the above-described steps were performed from the front side, but in the subsequent steps, the assembly can be performed from the back side.

Next, from the back side of the base member 110, the fixing member F4 is inserted into the through hole T4 and engaged with the engaging hole L4 of the boss 302A. Thereby, the power supply unit 300 is fixed in the storage unit 113 (see FIG. 18). At this time, the power supply unit 300 is pulled toward the bottom wall of the storage unit 113 by screwing the fixing member F4, which is a screw, into the engagement hole L4. Then, the first pressing portion 306 of the first terminal 304 of the power source portion 300 abuts on the conductive shaft 31 exposed on the bottom wall of the storage portion 113 while being elastically deformed. As a result, the conducting shaft 31 is electrically connected to one of the electrodes of the power source section 300 . In addition, since the first pressing portion 306 is bifurcated by the slits 306A, it can preferably elastically contact each of the two current-carrying shafts 31 . Further, the second packing P2 fitted on the boss 302A is pressed against the bottom wall of the storage portion 113, thereby preventing water from entering the storage portion 113 through the through hole T4. Also, the waterproof plug 4 is fitted into the concave portion 111K to prevent water from entering the storage portion 113 from the current-carrying shaft 31 .

Next, the engaging hole 170B of the sheet metal member 170 is inserted into the boss 117 protruding from the bottom wall of the recess 111F, and the sheet metal member 170 is placed on the bottom of the recess 111F. Then, the first conducting screw S1 is inserted through the engaging hole 170A and screwed into the first conducting hole H1 to be fixed (see FIG. 16). As a result, the head portion of the first conducting screw S1 abuts against the peripheral edge of the engagement hole 170A of the sheet metal member 170, and electrical continuity with the sheet metal member 170 is ensured. Further, in this state, the tip of the first conducting screw S1 protrudes from the first conducting hole H1 into the housing portion 113 and abuts on the second pressing portion 309 of the second terminal 307 while being pressed. As a result, the sheet metal member 170 is electrically connected to the second terminal 307 via the first conducting screw S1. A third packing P3 is fitted on the shaft of the first conducting screw S1. This prevents water from entering the storage portion 113 through the first conducting hole H1.

In the preceding stage of the above process, the storage portion 113 has only the first conducting hole H1 as an internal space, and the opening on the front surface and the through hole T4 on the back surface of the base member 110 are kept liquid-tight. state. Therefore, it is possible to perform a liquid-tightness test in the housing portion 113 using the first conducting hole H1 before the first conducting screw S1 is assembled.

Specifically, first, the outer surface (front side surface) of the base member 110 is fitted into the inner surface (back side surface) of the second front cover 130 . Further, the base member 110 to which the second front cover 130 is attached in this way is fitted into the inner surface (rear surface) of the first front cover 120 . As a result, the convex portion 151B of the lens 150 is exposed from the openings 120A and 130A, and the fixing member F1 arranged around the peripheral edge of the convex portion 151B is hidden. covered. Also, in this state, the engaging projections 134 and the bosses 135 of the second front cover 130 are engaged with the engaging recesses 111C and 111D on the front surface of the base member 110, respectively. Further, the engagement rib 136 of the second front cover 130 and the engagement rib 155 of the lens 150 are engaged with each other, and the boss 121 for conducting electricity of the first front cover 120 is connected to the through hole 132A of the second front cover 130 and the base. The bosses 122 for fixing the first front cover 120 are engaged with the engaging recesses 132B on the front surface of the second front cover 130, respectively. In this state, the fixing members F2 are inserted through the through holes T2 from the back side of the base member 110, and are engaged with the engaging holes L2 to be fixed.

In the above process, an example is shown in which the second front cover 130 and the first front cover 120 are assembled in this order to the base member 110 to which the lens 150 is assembled. It can also be assembled first and then combined with the assembly of the base member 110 .

(See FIG. 16). As a result, the sheet metal member 170 is sandwiched between the head of the second conducting screw S2 and the conducting boss 121, and electrical continuity between the sheet metal member 170 and the first front cover 120 is ensured. In other words, the current path from the power source section 300 to the first front cover 120 as a front cover member is conductive to the boss 121 of the first front cover 120 and the power source section 300 on the back surface of the base member 110 . and a sheet metal member 170 that is routed on the back surface of the base member 110 and forms an electrical path. As a result, electrical continuity between the first front cover 120 and the positive electrode of the power supply section 300 is ensured via the sheet metal member 170 .

In this way, the energization path from the positive electrode of the power supply unit 300 is pulled out from the inside of the storage unit 113 to the back surface of the base member 110 and passes through the sheet metal member 170. It is electrically connected to the first front cover 120 by being electrically connected to the through boss 121 for electricity. In this manner, ensuring electrical continuity between the first front cover 120 and the positive electrode of the power source section 300 can be easily performed by working from the back side of the base member 110 .

Next, the plug member 180 is fitted into the lightening recess 111F to which the sheet metal member 170 is assembled. As a result, the space into which water can enter is filled in the cutout recess 111F.

Then, the back cover 140 is assembled. Specifically, first, the engaging claws 143 are engaged with the engaging pieces 130D of the second front cover 130 while the rear cover 140 is slightly inclined with respect to the assembly direction. Then, the inner surface of the back cover 140 and the outer surface of the base member 110 are brought together. As a result, substantially the entire back surface of the base member 110 is covered, and the fixing member F2 that fixes the first front cover 120 and the second front cover 130 is hidden. In this state, the boss 144 is engaged with the engagement recess 111J of the base member 110, and the boss 145 is abutted against the boss 117 of the base member 110. As shown in FIG. Then, the fixing member F3 is inserted through the through hole T3 from the bottom surface of the recessed portion 141 of the back cover 140, and is engaged with the engaging hole L3 to be fixed.

Also, in this state, the insertion portion 142 is in a state of covering the shaft support portion 112 by being matched with the insertion portion 133 on the second front cover 130 side. Then, the ring member 71 is fitted to the distal end of the insertion portion 142 of the rear cover 140 and the insertion portion 133 of the second front cover 130 . As a result, the insertion portions 133 and 142 are kept in the aligned state, are prevented from opening, and are restricted from rattling.

Finally, the decorative plate 160 is fitted into the recessed portion 141 . Specifically, a double-faced tape 164 is attached to either one of the facing surfaces of the decorative plate 160 or the recessed portion 141, and the engaging protrusions 161, 162, and 163 of the decorative plate 160 are attached to the bottom wall of the recessed portion 141.
