It is not provided with in the opposite side of this two light guide section 21b, 21c as the press-in protuberance 21d of the intrusion relative to through hole 15a of light guide section 21b, 21c, is i.e. not provided with the right flank of light guide section 21b in left side and the left surface of the light guide section 21c on right side.Therefore, even if the spacing each other of the spacing each other of two light guide section 21b, 21c and two through hole 15a also is not able to insert two light guide section 21b, 21c the most swimmingly through hole 15a with high accuracy configuration, it is possible to be assembled into the state that the lower surface of the upper surface and display part 21a that make two to insert protuberance 15 reliably abuts.

Embodiments described above can be applied various changes.Such as, citing illustrates the light guiding lens 21 with two light guide sections 21b, 21c, even if having a light guide section, the light guiding lens of light guide section of more than three also is able to arrange identical bulkhead portion, and insert protuberance by arranging in body shell 10 side, it is possible to there is identical water-proof function.

Citing illustrates the structure that the lower surface periphery from display part 21a makes bulkhead portion 21aa the most at right angles to stretch out, it is also possible to for oliquely downward stretching out the structure blocking moisture.

It addition, the light source citing as luminous displaing part 20 illustrates LED, water proof structure of the present utility model is equally applicable to the situation with bulb as light source.

And, in the luminous displaing part 20 that citing represents, citing illustrates by arranging intrusion (press-in protuberance 21d) at light guide section 21b, 21c and being pressed into through hole 15a this light guiding lens 21 is fixed on the structure of body shell 10, but can also for omit involved by press-in protuberance 21d and only make light guide section 21b, 21c insert through hole 15a, the structure that fixing means is carried out by other bonding or screw fastening etc..

Citing represents the charger 1 of form making set of cells 2 slide and to install, take off, but the luminous displaing part of the charger of form that this utility model can also apply to insert set of cells and installs, takes off.It addition, be not limited to the charger of set of cells, it is also possible to the water proof structure of the luminous displaing part being widely used in other electrical equipments such as electric tool, electromotor.

In the case of omitting the press-in protuberance 21d of light guide section 21b, 21c as described above, it is possible to improve the water proofing property of this luminous displaing part 20 further by arranging waterproof protuberance 15b in through hole 15a side as shown in figure 15.Waterproof protuberance 15b is arranged in the complete cycle scope of the respective inner peripheral surface of two through hole 15a.In the assembling stage of light guiding lens 21, also will insert the stage in through hole 15a by two light guide section 21b, 21c, this two light guide section 21b, 21c are pressed into the inner circumferential side of waterproof protuberance 15b respectively.Owing to waterproof protuberance 15b is pressed against two light guide section 21b, 21c respectively, thus prevent the moisture such as the rainwater of the oral area entrance from through hole 15a from entering the inside (controlling substrate 30 side) of this charger 1.So, owing to going back in addition to the water-proof function except above-mentioned bulkhead portion 21aa and with the water-proof function of waterproof protuberance 15b, it is possible to improve the water proofing property of this luminous displaing part 20 further.

The upper end that waterproof protuberance 15b was arranged at and inserted protuberance 15 separates the inboard at suitable interval.Therefore, waterproof protuberance 15b is not the root (near upper end) at light guide section 21b, 21c, but the position of appropriately distance is separated in side forward, abutted in the range of the flexure (elastic deformation) allowing two light guide section 21b, 21c.Because waterproof protuberance 15b is connected to leave the position of appropriately distance from the root of light guide section 21b, 21c, even if so in the case of the spacing of two through hole 15a is the most consistent with the spacing of two light guide section 21b, two light guide section 21b also are able to, by because of its flexure, spacing changes, insert in through hole 15a the most swimmingly.It is possible to be assembled into the state that the lower surface of the upper surface and display part 21a that make two to insert protuberance 15 reliably abuts, it addition, the worry of display part 21a breakage etc. in the case of can eliminating within by force firmly by two light guide section 21b press-in through hole 15a.

Waterproof protuberance is arranged in addition to the structure of through hole 15a side except representing such as the example above, it is also possible to be configured to be arranged on light guide section 21b, 21c side.It addition, waterproof protuberance can also be configured to be arranged on through hole 15a side and these both sides of light guide section 21b, 21c side.

Further, even if waterproof protuberance is in the case of the either side being arranged at light guide section 21b side or through hole 15a side, also possesses the water-proof function that moisture such as preventing the rainwater entered from the oral area of through hole 15a enters in body shell.Therefore, if only can be achieved with the enough waterproof of this luminous displaing part by the water-proof function of above-mentioned waterproof protuberance, then can omit the bulkhead portion 21aa of display part 21a side and insert either one in protuberance 15 or both sides.By omitting the bulkhead portion 21aa of display part 21a and inserting the one side or both sides in protuberance 15, it is possible to realize the shaping mould of light guiding lens 21 or the simplification of the shaping mould of upper shell 11, the cost that it is possible to realize this charger reduces.

It addition, waterproof protuberance is because becoming resistance when light guide section 21b, 21c insert through hole 15a so also serving as intrusion and function.Therefore, even if so omitting the press-in protuberance 21d of light guide section 21b, 21c side and in the case of arranging waterproof protuberance 15b, the function as intrusion based on waterproof protuberance 15b, light guide section 21b, 21c are retained as to extract relative to through hole 15a.Wherein, it is also possible to be configured to by arranging press-in protuberance 21d at light guide section 21b, 21c as represented in the example above, and waterproof protuberance 15b is set at through hole 15a, and be able to ensure that the water-proof function in this through hole 15a, and realize more firm press-in.Even if be configured to and with press-in protuberance 21d and waterproof protuberance 15b in the case of, it is also possible to elastic deformations based on them guarantee the watertightness (close property) between the inner peripheral surface of light guide section 21b, 21c and through hole 15a it is thus possible to substantially ensure that the water-proof function in through hole 15a of this luminous displaing part 20.

Figure 16 represents the charger 1 that body shell 10 applies change.At the upper surface of the body shell 10 shown in Figure 16, and the front side of holding section 14h is provided with air vent 16.The exogenous QI being imported into the cooling in body shell 10 is discharged from this air vent 16.Lower section at air vent 16 is built-in with cooling fan 17 as shown in figure 17.Cooling fan 17 is the so-called Sirocco fan of built-in fan main body in the fan drum 17c of substantially circular plate type, is fixed with raised state in the bottom of body shell 10.

The periphery top of fan drum 17c is provided with outlet 17a.Outlet 17a rectangular ground opening.In fig. 17, rotated counterclockwise by fan main body, thus the cooling wind in body shell 10 is inhaled into from the sidepiece of fan drum 17c, then, after the inner circumferential wall counterclockwise flow of fan drum 17c, is discharged upward from outlet 17a.At the most opposed two of the periphery of fan drum 17c, sidepiece is provided with semicircular installation edge part 17b.At two, edge part 17b is installed to be separately provided for for installing the screwed hole 17ba that screw passes.Cooling fan 17 is by being screwed on lower house 12 side through two of two screwed hole 17ba installation screws.

About the installment state of cooling fan 17, need to make its setting height(from bottom) compact to spend the time.About the position of the circumference of cooling fan 17, it is installed on position after the flat-hand position of horizontal location (position shown in double dot dash line Figure 18) circumferentially offsets as shown in figure hollow core arrow, the upper surface discharging it mouthful 17a to the inclination attitude (position indicated by the solid line in Figure 18) tilted.It addition, cooling fan 17 is installed on the position making the lower end of its fan drum 17c substantially abut with the bottom of lower house 12.

As a result, about the cooling fan 17 setting height(from bottom) from the bottom of lower house 12, for L0 under making the flat-hand position of upper surface horizontal location of outlet 17a, for L1 under the inclination attitude making the upper surface of outlet 17a tilt.Under inclination attitude, the right part of outlet 17a is positioned at the highest position, and the height of this right part is the height that the upper end of the installation edge part 17b with right side is much the same.So, by making cooling fan 17 mounted to circumferentially offset the posture towards more tilting by the direction that the left side of its outlet 17a is the lowest from flat-hand position, it is thus possible to make this outlet 17a be positioned at lower position, thus enable that the height dimension of body shell 10 is compact.

Cooling fan 17 is mounted to circumferentially offset the posture that the lowest direction, side tilts that more keeps left of the upper surface towards its outlet 17a, corresponding, and 3 wall portion 16a of air vent 16 size that the wall portion 16a of side stretches out downwards that more keeps left is the biggest.Thus 3 wall portion 16a all abut with outlet 17a and keep the inclination attitude of this outlet 17a.
