In addition, as shown in Figure 7, lower cover 16 has electric wire leadout hole 62, this electric wire leadout hole 62 be formed in perisporium 50b, central part office between springy locking member 52, this electric wire leadout hole 62 runs through perisporium 50b and at openend surface 56 split sheds, can be directed to outside to make the electric wire 21 be installed on box main body 12 by electric wire leadout hole 62.Therefore, electric wire leadout hole 62 is formed in outer circumferential side and blocks water in the forming region of wall 58, this outer circumferential side block water wall 58 be set to from openend surface 56 give prominence to, to extend along perisporium 50a to 50c, and outer circumferential side blocks water, wall 58 is separated in the circumferential by electric wire leadout hole 62.In addition, as shown in Figure 7, on the inner peripheral surface side of perisporium 50b, on the either side of the circumference of electric wire leadout hole 62, the openend surface 56 of lower cover 16 forms angled end face 64, and this angled end face is connected to outer circumferential side with obtuse angle θ and blocks water on the inner surface of wall 58.Therefore, during under shed lower cover 16 being installed to box main body 12, can advantageously prevent following problem: the electric wire 21 of being drawn by electric wire leadout hole 62 is maintained between the end surfaces of the openend surface 56 of lower cover 16 and the perisporium 30b of box main body 12.It should be noted that obtuse angle θ is more preferably set to the obtuse angle of 135 ° or more.
On the other hand, the diapire 66 of lower cover 16 has inclined surface 68, it has a down dip from perisporium 50d side towards perisporium 50b side direction, perisporium 50d side is corresponding with the upper end (right side in Fig. 4) of the side on longitudinal direction, and perisporium 50b is corresponding with the bottom (left side in Fig. 4) of the opposite side on longitudinal direction.At this, when considering the installing space etc. of electric connection box 10, the downward-sloping angle A (see Fig. 4 and Fig. 8) of inclined surface 68 can be set as required.In the present embodiment, angle A is set as 10 °.In addition, osculum 70a and 70b is formed in the opposite end on the longitudinal direction of diapire 66, and this longitudinal direction is the incline direction of diapire 66, and this osculum 70a and 70b is through diapire 66.Electric wire leadout hole 62 is arranged on the side, bottom in perisporium 50b, on the incline direction of namely diapire 66, to be positioned at least significant end opposite side.Should note, as shown in Figure 6, in the present embodiment, osculum 70a is set directly at the part below of region G, outer circumferential side wall 58 and the inner circumferential side wall 60 that blocks water that blocks water separates in the circumferential at G place, region, even if thus water enters from region G, also can guarantee that water quickly move through osculum 70a and discharges.
In the electric connection box 10 of the present embodiment with said structure, the diapire 66 of lower cover 16 is provided with inclined surface 68, and it is downward-sloping towards the bottom of opposite side from the upper end of side.In addition, osculum 70a and 70b be arranged on inclined surface 68, opposite end on the longitudinal direction of electric connection box 10, this longitudinal direction is the incline direction of inclined surface 68.Therefore, car body shown in Figure 1, motorcycle does not have the non-inclined state of run-off the straight relative to stayed surface under, enter the inner and water having arrived the diapire 66 of lower cover 16 of electric connection box 10 by the gap between the mounting surface of the box main body 12 of electric connection box 10 and upper and lower covers 14 and 16 to flow downward along downward-sloping inclined surface 68, thus assemble towards osculum 70a, and discharged rapidly by osculum 70a, osculum 70a is arranged on side, bottom, is namely positioned on the corresponding perisporium 50b of the opposite side of least significant end.
Next, Fig. 8 (a) and Fig. 8 (b) is utilized to describe the situation of car body relative to stayed surface run-off the straight of motorcycle.Fig. 8 (a) and Fig. 8 (b) schematically shows the various situations of car body 72 relative to stayed surface 74 run-off the straight of motorcycle.It should be noted that in Fig. 8 (a) and Fig. 8 (b), for the ease of understanding, conceptually illustrating car body 72 and stayed surface 74 with imaginary line, and showing the cross section of electric connection box 10 in the way to enlarge.
Fig. 8 (a) illustrates the state using side foot-stand 76 to stop motorcycle, and car body 72 self tilts to the left relative to stayed surface 74 in this condition.In this case, osculum 70a and 70b be arranged in inclined surface 68 is arranged as and makes it be spaced apart from each other on the left and right directions of motorcycle, electric connection box 10 is arranged in car body 72 simultaneously, be positioned on the left side be lowered when motorcycle is stopped to make the bottom of inclined surface 68 and perisporium 50b, osculum 70a is set to be located at the perisporium 50b side corresponding with the least significant end of inclined surface 68.Therefore, when motorcycle is stopped, on the diapire 66 of lower cover 16, inclined surface 68 towards the gradient of osculum 70a more precipitous (A+ α), i.e. the inclined angle alpha that tilts from the non-inclined state (vertical direction) relative to stayed surface 74 of inclination car body 72 further.The effect of water and the effect by osculum 70a draining is collected towards osculum 70a therefore, it is possible to more advantageously obtain.
Fig. 8 (b) illustrates when during advancing, motorcycle is turned right or unexpectedly tilts to the right, and car body 72 self is relative to the state of stayed surface 74 inclination β angle to the right.In this case, because electric connection box 10 is relative to vertical direction inclination β angle, so be positioned at vertical direction bottom with the end (right side in Fig. 8) on the perisporium 50d side that the top of non-inclined state lower inclined surface 68 is corresponding, and inclined surface 68 is downward-sloping towards the end on perisporium 50d side.Therefore, water along inclined surface 68 to dirty, and is collected into the upper end of side, can be discharged rapidly to make water by the osculum 70b be arranged in the upper end of this side.
That is, in traditional structure, assuming that car body 72 is in the non-inclined state relative to stayed surface 74 not yet run-off the straight, then osculum is only arranged under non-inclined state relative on the lower side of the incline direction of inclined surface 68.For this reason, there are the following problems: when car body 72 is in the downward-sloping direction rightabout surface thereof with inclined surface 68, due to inclined surface 68 not arranging osculum, thus the water collecting inclined surface 68 side cannot be discharged.According to the present embodiment, because osculum 70a and 70b is arranged in the opposite end of the incline direction of inclined surface 68, even if so when car body 72 the downward-sloping side with inclined surface 68 in the opposite direction surface thereof time, water also can be discharged by osculum 70b rapidly.Therefore, though when be arranged on according to the electric connection box 10 of the present embodiment car body 72 may relative to the motorcycle of stayed surface 74 run-off the straight in time, the electric connection box 10 according to the present embodiment also can obtain the effective drainage effect being applicable to motorcycle.
Although more than describe in detail embodiments of the invention, the invention is not restricted to above-mentioned specific descriptions.Such as, electric connection box 10 can be set as required and be arranged on setting direction in vehicle and position.Particularly, in a further embodiment shown in figure 9, electric connection box 10 is arranged in car body 72, be in the left side on lower position when being positioned at vehicle parking to make the upper end of inclined surface 68 (perisporium 50d side), and the upper-end part of driving of inclined surface 68 is in the level lower than the bottom (perisporium 50b side) when car body 72 is stopped in the vertical direction on (above-below direction in Fig. 9).In this manner, because osculum 70b is also arranged in the upper end of this side, even if so when car body 72 the downward-sloping side with inclined surface 68 in the opposite direction surface thereof time, water also can quickly move through osculum 70b and discharge.In addition, can prevent following problem: when vehicle parking, the angle of inclination of inclined surface 68 becomes excessive, to such an extent as to subvertical degree, inhibit drainability on the contrary.
In addition, electric wire leadout hole 62 is formed in perisporium 50b, and this wall is the sidewall be positioned on the side, bottom of inclined surface 68 of lower cover 16.According to the present embodiment, when car body 72 is stopped, bottom (perisporium 50b side) due to inclined surface 68 is positioned in the level higher than upper end (perisporium 50d side) in vertical direction, therefore, it is possible to advantageously anti-sealing is discharged by the electric wire leadout hole 62 be formed in the perisporium 50b of side, bottom.As a result, following problem can be prevented: the water of discharge may flow downward along electric wire 21, and causes electrical system to break down.
In addition, although described electric connection box 10 to be in the present embodiment arranged on form in motorcycle, the present invention is not limited thereto.Such as, even if when electric connection box 10 is arranged in the four-wheel automobile of car body relative to stayed surface not run-off the straight, suppose the heeling condition according to road surfaces, the upper end (osculum 70b side) on inclined surface 68 side also may be positioned in the level lower than the bottom (osculum 70a side) of the opposite side in vertical direction.Even if under these circumstances, also water can be discharged fast by the osculum 70b in the upper end of this side, thus realize effective drainage effect.
In addition, after suitably considering the installing space of electric connection box, the possibility being exposed to water etc., the angle of inclination of the inclined surface 68 be arranged in the diapire 66 of lower cover 16 and the quantity, position etc. of osculum can be changed.
