　なお、ボス２０とブロワケース１０とを別体で形成し、後からボス２０をブロワケース１０に取付けるようにしてもよい。その場合は、ブロワケース１０の側壁１２，１５に所定の間隔をあけて複数の孔（図示せず）を設け、これらの孔にボス２０を挿入するようにしてもよい。また、機器収容部１１の周壁１３に所定の間隔をあけて筒状部材（図示せず）を配設し、これらの筒状部材にボス２０を挿入するようにしてもよい。なお、ブロワケース１０とボス２０とを一体成形することで、ボス２０を別途ブロワケース１０に対して位置合わせして取付ける必要が無くなり、ブロワユニット１００の製造コストの上昇を抑制できる。 The boss 20 and the blower case 10 may be formed separately, and the boss 20 may be attached to the blower case 10 later. In this case, a plurality of holes (not shown) may be provided at predetermined intervals on the side walls 12 and 15 of the blower case 10, and the boss 20 may be inserted into these holes. Alternatively, cylindrical members (not shown) may be provided at predetermined intervals on the peripheral wall 13 of the device housing portion 11, and the boss 20 may be inserted into these cylindrical members. In addition, since the blower case 10 and the boss 20 are integrally formed, it is not necessary to separately position and attach the boss 20 to the blower case 10, thereby suppressing an increase in the manufacturing cost of the blower unit 100.
　なお、ボス２０は円柱状でなくてもよい。強度が確保できれば円筒状であってもよいし、また角柱状あるいは角筒状であってもよい。ボス２０を円柱状または円筒状にすることで、係合クリップ６０，６１に対してボス２０が挿入される方向の自由度が増し、ブロワケース１０の汎用性を高めることができる。 ボ ス Note that the boss 20 need not be cylindrical. As long as the strength can be ensured, it may be cylindrical, prismatic or prismatic. By making the boss 20 cylindrical or cylindrical, the degree of freedom in the direction in which the boss 20 is inserted into the engagement clips 60 and 61 is increased, and the versatility of the blower case 10 can be increased.
　＜変形例１＞
　図４は、本変形例に係るブロワケースの側面図を示す。なお、図４には、取付脚部５０に設けられた係合リング６２，６３もあわせて図示している。 <Modification 1>
FIG. 4 shows a side view of a blower case according to this modification. FIG. 4 also shows engagement rings 62 and 63 provided on the mounting leg 50.
　図４に示すように、機器収容部１１の外周に沿って所定の間隔をあけて角柱形状の複数のボス２１，２２が設けられている。ボス２１は、気流吐出部１４の側壁１５に設けられ、ボス２２は、機器収容部１１と気流吐出部１４との連通部分１７（以下、単に連通部分１７という）に設けられている。また、ボス２１は、気流吐出部１４の側壁１５からＺ方向に沿ってブロワケース１０の外部に向けて延びるように設けられ、ボス２２は、連通部分１７からＺ方向に沿ってブロワケース１０の外部に向けて延びるように設けられている。 (4) As shown in FIG. 4, a plurality of prism-shaped bosses 21 and 22 are provided at predetermined intervals along the outer periphery of the device housing portion 11. The boss 21 is provided on the side wall 15 of the airflow discharge unit 14, and the boss 22 is provided on a communication portion 17 between the device housing portion 11 and the airflow discharge portion 14 (hereinafter simply referred to as a communication portion 17). The boss 21 is provided so as to extend from the side wall 15 of the airflow discharge portion 14 toward the outside of the blower case 10 along the Z direction, and the boss 22 extends from the communication portion 17 along the Z direction. It is provided so as to extend toward the outside.
　また、取付脚部５０に設けられた係合リング６２，６３は四角環状の部材であり、ボス２１，２２が係合リング６２，６３にそれぞれ挿通されて係合し、ブロワユニット１００が取付脚部５０に取付け固定されている。このようにボス２１，２２と係合リング６２，６３とをそれぞれ係合させることで、排気口１６がＸ方向に向けられ、かつ気流吐出部１４がＹ方向下側に配置されるように、ブロワユニット１００は取付脚部５０に取付けられる。 The engagement rings 62 and 63 provided on the attachment leg 50 are rectangular annular members, and the bosses 21 and 22 are inserted and engaged with the engagement rings 62 and 63, respectively, so that the blower unit 100 is attached to the attachment leg. It is attached and fixed to the part 50. By engaging the bosses 21 and 22 with the engagement rings 62 and 63 in this manner, the exhaust port 16 is directed in the X direction, and the airflow discharge portion 14 is disposed on the lower side in the Y direction. The blower unit 100 is attached to the attachment leg 50.
　本変形例によれば、ボス２１，２２を係合リング６２，６３にそれぞれ挿通させ、係合リング６２，６３のＹ方向下側の内壁面にボス２１，２２が引っかかるようにしてボス２１，２２を係合リング６２，６３に係合させている。このことにより、係合クリップ６０，６１のように外力を加えて先端部を押し拡げる必要が無く、ブロワユニット１００の取付作業がさらに簡便になる。 According to this modification, the bosses 21 and 22 are inserted through the engagement rings 62 and 63, respectively, and the bosses 21 and 22 are hooked on the inner wall surfaces of the engagement rings 62 and 63 below the Y direction. 22 is engaged with the engagement rings 62 and 63. This eliminates the need to apply an external force to push the tip end apart as in the case of the engagement clips 60 and 61, and the work of attaching the blower unit 100 is further simplified.
　なお、本変形例において、ボス２１，２２は角柱形状であるが、特にこれに限定されない。例えば、円柱状であっても、円筒状であってもよい。また、係合リング６２，６３は他の形状であってもよく、例えば、円環状であってもよい。 In the present modification, the bosses 21 and 22 have a prismatic shape, but are not particularly limited to this. For example, it may be cylindrical or cylindrical. Further, the engagement rings 62 and 63 may have another shape, for example, an annular shape.
　＜変形例２＞
　図５Ａは、本変形例に係るブロワケースの側面図を、図５Ｂは、ブロワケースの別の側面図をそれぞれ示す。図６Ａ，６Ｂは、ブロワケースのさらなる別の側面図をそれぞれ示す。なお、図５Ａ～６Ｂには、取付脚部５０に設けられた係合クリップ６０，６１もあわせて図示している。また、図５Ａ～６Ｂ中に示す矢印は、係合クリップに対してボスが取付けられる方向を示している。 <Modification 2>
FIG. 5A is a side view of a blower case according to the present modification, and FIG. 5B is another side view of the blower case. 6A and 6B show still another side view of the blower case, respectively. 5A to 6B also show engaging clips 60 and 61 provided on the mounting leg 50. Arrows shown in FIGS. 5A to 6B indicate directions in which bosses are attached to the engagement clips.
　本変形例では、図５Ａ～６Ｂに示すように、ブロワケース１０の外周側に所定の間隔をあけて４つのボスが設けられている。ボス２１は、気流吐出部１４の側壁１５に設けられ、ボス２２は、連通部分１７に設けられている。また、ボス２３は、回転軸３３ａを挟んでボス２２と反対側、つまり、連通部分１７の反対側に設けられ、ボス２４は、ボス２３よりも排気口１６に近い側に設けられている。 変 形 In this modification, as shown in FIGS. 5A to 6B, four bosses are provided on the outer peripheral side of the blower case 10 at predetermined intervals. The boss 21 is provided on the side wall 15 of the airflow discharge unit 14, and the boss 22 is provided on the communication portion 17. The boss 23 is provided on the opposite side of the boss 22 with respect to the rotation shaft 33a, that is, on the opposite side of the communication portion 17, and the boss 24 is provided on the side closer to the exhaust port 16 than the boss 23.
　また、図５Ａ，６Ａに示すように、ボス２１、２４は円柱状であり、ボス２２，２３は変形した半円柱形状である。あるいは、図５Ｂに示すように、ボス２１、２２ａ、２４は円柱状であり、ボス２３は変形した半円柱状であってもよい。また、図６Ｂに示すように、ボス２１、２３ａ、２４は円柱状であり、ボス２２は変形した半円柱状であってもよい。その他、全てのボス２１～２４が円柱状であってもよいし、あるいは、半円柱形状であってもよい。なお、ボスの形状は、取り付けられる係合クリップの形状と対応していれば保持力が高くなるため、より好ましい。また、ボス２１は、気流吐出部１４の側壁１５からＺ方向に沿ってブロワケース１０の外部に向けて延びるように設けられ、ボス２２は、機器収容部１１の側壁１２からＺ方向に沿ってブロワケース１０の外部に向けて延びるように設けられている。一方、ボス２３，２４は、機器収容部１１の周壁１３に沿って設けられ、Ｚ方向に沿ってブロワケース１０の外部に向けて延びている。なお、ボス２３，２４は、機器収容部１１の側壁１２に設けられるようにしてもよい。 5A and 6A, the bosses 21 and 24 are cylindrical, and the bosses 22 and 23 are deformed semi-cylindrical shapes. Alternatively, as shown in FIG. 5B, the bosses 21, 22a, 24 may have a cylindrical shape, and the boss 23 may have a deformed semi-cylindrical shape. Further, as shown in FIG. 6B, the bosses 21, 23a, and 24 may have a cylindrical shape, and the boss 22 may have a deformed semi-cylindrical shape. In addition, all the bosses 21 to 24 may be cylindrical or semi-cylindrical. The shape of the boss is more preferable if it corresponds to the shape of the engaging clip to be attached, because the holding force is increased. The boss 21 is provided so as to extend from the side wall 15 of the airflow discharge unit 14 toward the outside of the blower case 10 along the Z direction, and the boss 22 extends from the side wall 12 of the device accommodating unit 11 along the Z direction. It is provided so as to extend toward the outside of the blower case 10. On the other hand, the bosses 23 and 24 are provided along the peripheral wall 13 of the device accommodating portion 11 and extend toward the outside of the blower case 10 along the Z direction. Note that the bosses 23 and 24 may be provided on the side wall 12 of the device housing section 11.
　図５Ａ～６Ｂに示すように、４つのボス２１～２４のうち所定の２つのボスを取付脚部５０の係合クリップ６０，６１にそれぞれ係合させることで、排気口１６の位置を変えることができる。 As shown in FIGS. 5A to 6B, the position of the exhaust port 16 can be changed by engaging predetermined two bosses of the four bosses 21 to 24 with the engaging clips 60 and 61 of the mounting leg 50, respectively. Can be.
　例えば、図５Ａ，５Ｂに示すように、ボス２１，２２または２２ａと係合クリップ６０，６１とをそれぞれ係合させてブロワユニット１００を取付脚部５０に取付けることで、排気口１６をＸ方向に向けて、かつ気流吐出部１４をＹ方向下側に配置することができる。図６Ａ，６Ｂに示すように、ボス２３または２３ａ，２４と係合クリップ６０，６１とをそれぞれ係合させてブロワユニット１００を取付脚部５０に取付けることで、排気口１６をＹ方向下側に向けて、かつ気流吐出部１４をＸ方向に配置することができる。 For example, as shown in FIGS. 5A and 5B, the bosses 21, 22, or 22a are engaged with the engagement clips 60, 61 to attach the blower unit 100 to the attachment legs 50, so that the exhaust port 16 is moved in the X direction. , And the airflow discharge unit 14 can be arranged on the lower side in the Y direction. As shown in FIGS. 6A and 6B, the boss 23 or 23 a, 24 is engaged with the engagement clips 60, 61, respectively, and the blower unit 100 is attached to the attachment leg 50. , And the airflow discharge unit 14 can be arranged in the X direction.
　このように、係合クリップ６０，６１に係合されるボスの配置を規定することで、取付脚部５０に取付けられたブロワユニット１００の排気口１６の向き及び位置を変更することができる。また、係合クリップ６０，６１とボス２１～２４のうち２つのボスとを係合させることでブロワユニット１００を取付脚部５０に安定して取付けることができる。なお、係合クリップに係合されるボスは１つであってもよい。ボスの強度やブロワユニット１００の重量等にもよるが、一つのボスに対して一つの係合部を係合させても、ブロワユニット１００を取付脚部５０に取付け固定することができる。その場合、係合させるボスは、ブロワユニット１００の重心、特に質量の大きいモータ３０の重心に近い場所を選択するようにするとよい。例えば、図５Ａ，５Ｂに示すように、Ｙ方向下側を重力方向とすると、排気口１６をＸ方向に向けて、かつ気流吐出部１４をＹ方向下側に配置する場合は、ボス２２と係合クリップ６０とを係合させるとよい。図６Ａ，６Ｂに示すように、排気口１６をＹ方向下側に向けて、かつ気流吐出部１４をＸ方向に配置する場合は、ボス２４と係合クリップ６０とを係合させるとよい。 By defining the arrangement of the bosses to be engaged with the engagement clips 60 and 61 as described above, the direction and position of the exhaust port 16 of the blower unit 100 attached to the attachment leg 50 can be changed. Further, by engaging the engagement clips 60 and 61 with two bosses of the bosses 21 to 24, the blower unit 100 can be stably attached to the attachment leg 50. Note that one boss may be engaged with the engagement clip. Depending on the strength of the boss, the weight of the blower unit 100, and the like, the blower unit 100 can be mounted and fixed to the mounting leg 50 even if one engaging portion is engaged with one boss. In this case, it is preferable to select a location near the center of gravity of the blower unit 100, particularly the center of gravity of the motor 30 having a large mass, as the boss to be engaged. For example, as shown in FIGS. 5A and 5B, when the lower side in the Y direction is the gravitational direction, when the exhaust port 16 is oriented in the X direction and the airflow discharge unit 14 is arranged on the lower side in the Y direction, the boss 22 is used. It is preferable to engage the engaging clip 60. As shown in FIGS. 6A and 6B, when the exhaust port 16 is oriented downward in the Y direction and the airflow discharge section 14 is arranged in the X direction, the boss 24 and the engagement clip 60 may be engaged.
　また、ボス２１～２４が設けられる位置のそれぞれに複数のボスを配置し、それに対応させて取付脚部５０に係合クリップ等の係合部をさらに設けるようにしてもよい。このようにすることで取付脚部５０がブロワユニット１００を支持する支持強度を高めることができる。 Alternatively, a plurality of bosses may be arranged at each of the positions where the bosses 21 to 24 are provided, and an engaging portion such as an engaging clip may be further provided on the mounting leg portion 50 in correspondence with the plurality of bosses. By doing so, the support strength of the mounting leg 50 supporting the blower unit 100 can be increased.
　また、図示しないが、ボス２１～２４に対する係合クリップ６０，６１の角度を図５Ａ～６Ｂに示す角度と異ならせるように調整し、ボス２１～２４のうち２つを係合クリップ６０，６１で挟持することで、図５Ａ～６Ｂに示す排気口１６の向きをＺ軸周りに回転させることができ、排気口１６の位置を設定する自由度を高めることができる。このことにより、取付脚部５０に対するブロワユニット１００の取付配置の自由度を高められる。 Although not shown, the angles of the engaging clips 60, 61 with respect to the bosses 21 to 24 are adjusted to be different from the angles shown in FIGS. 5A to 6B, and two of the bosses 21 to 24 are connected to the engaging clips 60, 61. 5A to 6B, the direction of the exhaust port 16 shown in FIGS. 5A to 6B can be rotated around the Z axis, and the degree of freedom in setting the position of the exhaust port 16 can be increased. Thereby, the degree of freedom of the mounting arrangement of the blower unit 100 to the mounting leg 50 can be increased.
　＜変形例３＞
　図７は、本変形例に係るブロワケースの側面図を、図８は、ブロワケースの別の側面図をそれぞれ示す。なお、図７，８には、取付脚部５０に設けられた係合クリップ６０，６１もあわせて図示している。また、図７，８中に示す矢印は、係合クリップ６０，６１に対してボスが取付けられる方向を示している。 <Modification 3>
FIG. 7 shows a side view of a blower case according to the present modification, and FIG. 8 shows another side view of the blower case. 7 and 8, the engagement clips 60 and 61 provided on the mounting leg 50 are also shown. The arrows shown in FIGS. 7 and 8 indicate the direction in which the boss is attached to the engaging clips 60 and 61.
　図５，６に示す構成と、図７，８に示す本変形例の構成とでは、ブロワケース１０に設けられたボスの個数が異なり、変形例２では４つのボス２１～２４が設けられているのに対し、本変形例に示す構成では、ボスが１個追加され、５つのボス２１～２５がブロワケースに設けられている。追加されたボス２５は、回転軸３３ａを挟んで排気口１６の反対側に設けられている。より具体的には、回転軸３３ａを挟んでボス２１の反対側に設けられている。 The number of bosses provided on the blower case 10 is different between the configuration shown in FIGS. 5 and 6 and the configuration of the present modification shown in FIGS. 7 and 8. In the second modification, four bosses 21 to 24 are provided. On the other hand, in the configuration shown in this modification, one boss is added, and five bosses 21 to 25 are provided in the blower case. The added boss 25 is provided on the opposite side of the exhaust port 16 across the rotation shaft 33a. More specifically, it is provided on the opposite side of the boss 21 across the rotation shaft 33a.
　このように、５つのボス２１～２５のうち所定の２つのボスを取付脚部５０の係合クリップ６０，６１に係合させることよっても、排気口１６の位置を変えることができる。 As described above, the position of the exhaust port 16 can also be changed by engaging two predetermined bosses of the five bosses 21 to 25 with the engaging clips 60 and 61 of the mounting leg 50.
　例えば、図７に示すように、ボス２３，２５と係合クリップ６０，６１とをそれぞれ係合させてブロワユニット１００を取付脚部５０に取付けることで、排気口１６をＸ方向に向けて、かつ気流吐出部１４をＹ方向上側に配置することができる。図８に示すように、ボス２２，２５と係合クリップ６０，６１とをそれぞれ係合させてブロワユニット１００を取付脚部５０に取付けることで、排気口１６をＹ方向上側に向けて、かつ気流吐出部１４をＸ方向に配置することができる。 For example, as shown in FIG. 7, the bosses 23, 25 and the engagement clips 60, 61 are respectively engaged to attach the blower unit 100 to the attachment legs 50, so that the exhaust port 16 is directed in the X direction. In addition, the airflow discharge unit 14 can be arranged on the upper side in the Y direction. As shown in FIG. 8, the bosses 22, 25 and the engaging clips 60, 61 are respectively engaged to attach the blower unit 100 to the attachment legs 50, so that the exhaust port 16 faces upward in the Y direction, and The airflow discharge unit 14 can be arranged in the X direction.
　このように、係合クリップ６０，６１に係合されるボスの配置を規定することで、変形例２と同様に、取付脚部５０に取付けられたブロワユニット１００の排気口１６の向き及び位置を変更することができるとともに、排気口１６の向き及び位置の設定の自由度をさらに高めることができる。また、係合クリップ６０，６１とボス２１～２５のうち２つのボスとを係合させることでブロワユニット１００を取付脚部５０に安定して取付けることができる。なお、一つの係合クリップに一つのボスを係合する場合には、変形例２と同様に、ブロワユニット１００の重心に近い場所にあるボスを選択するとよい。例えば、図７に示すように、排気口１６をＸ方向に向けて、かつ気流吐出部１４をＹ方向上側に配置する場合は、ボス２３と係合クリップ６０とを係合させるか、又は、ボス２５と係合クリップ６１とを係合させるとよい。また、図８に示すように、排気口１６をＹ方向上側に向けて、かつ気流吐出部１４をＹ方向上側に配置する場合は、ボス２５と係合クリップ６０とを係合させるか、又は、ボス２２と係合クリップ６１とを係合させるとよい。 By defining the arrangement of the bosses to be engaged with the engagement clips 60 and 61 in this manner, the orientation and the position of the exhaust port 16 of the blower unit 100 attached to the attachment leg 50 as in the second modification. Can be changed, and the degree of freedom in setting the direction and position of the exhaust port 16 can be further increased. Further, by engaging the engaging clips 60 and 61 with two bosses of the bosses 21 to 25, the blower unit 100 can be stably mounted on the mounting leg 50. When one boss is engaged with one engagement clip, a boss located near the center of gravity of the blower unit 100 may be selected as in the second modification. For example, as shown in FIG. 7, when the exhaust port 16 is oriented in the X direction and the airflow discharge unit 14 is arranged on the upper side in the Y direction, the boss 23 and the engagement clip 60 are engaged, or The boss 25 and the engaging clip 61 are preferably engaged. In addition, as shown in FIG. 8, when the exhaust port 16 is oriented upward in the Y direction and the airflow discharge unit 14 is arranged upward in the Y direction, the boss 25 and the engaging clip 60 are engaged, or , The boss 22 and the engagement clip 61 may be engaged.
　また、ボス２１～２５に対する係合クリップ６０，６１の角度を異ならせるように調整してボス２１～２５のうち２つのボスを係合クリップ６０，６１で挟持することで、排気口１６の向きをＺ軸周りに回転させることができるのも変形例２と同様である。 In addition, by adjusting the angles of the engaging clips 60 and 61 with respect to the bosses 21 to 25 so as to be different from each other, and holding two bosses of the bosses 21 to 25 with the engaging clips 60 and 61, the direction of the exhaust port 16 is adjusted. Can be rotated about the Z axis, similarly to the second modification.
　なお、変形例２，３では、それぞれブロワケース１０の外周側に４個または５個のボスが設けられた例を示したが、特にこれに限定されない。例えば、図３に示すように６個以上のボスが設けられていてもよい。また、例えば、変形例２に示す構成において、図５，６に示す位置にボスが設けられていればよく、それ以外の位置に別のボスが設けられていてもよい。また、変形例３に示す構成において、図７，８に示す位置にボスが設けられていればよく、それ以外の位置に別のボスが設けられていてもよい。 In addition, in the modified examples 2 and 3, the example in which four or five bosses are provided on the outer peripheral side of the blower case 10 is shown, but the present invention is not particularly limited to this. For example, as shown in FIG. 3, six or more bosses may be provided. Further, for example, in the configuration shown in Modification Example 2, a boss may be provided at the position shown in FIGS. 5 and 6, and another boss may be provided at other positions. Further, in the configuration shown in Modification 3, a boss may be provided at the position shown in FIGS. 7 and 8, and another boss may be provided at other positions.
　＜変形例４＞
　図９は、本変形例に係るブロワケースを斜め下側から見た図を示す。本変形例に示す構成と変形例２に示す構成とでは、ボスの個数及びその配置位置が異なっており、具体的には、図９に示すように、気流吐出部１４において互いに対向する側壁１５のそれぞれに、ボス２１，２６が設けられている。ボス２１とボス２６はＺ方向から見て重なる位置にある。また、連通部分１７において互いに対向する側壁１２のそれぞれに、ボス２２，２７が設けられている。ボス２２とボス２７はＺ方向から見て重なる位置にある。また、機器収容部１１の周壁１３に沿ってブロワケースの外部に向けて延びるようにボス２３，２４，２８，２９がそれぞれ設けられている。ボス２３とボス２８、ボス２４とボス２９は、それぞれＺ方向から見て重なる位置にある。なお、図示しないが、取付脚部５０及び係合クリップ６０，６１は、Ｚ方向に沿ってブロワケース１０の両側にそれぞれ設けられている。 <Modification 4>
FIG. 9 is a diagram illustrating the blower case according to the present modification as viewed obliquely from below. The number of bosses and the arrangement position thereof are different between the configuration shown in the present modification and the configuration shown in Modification 2. Specifically, as shown in FIG. Are provided with bosses 21 and 26, respectively. The boss 21 and the boss 26 are located at positions overlapping each other when viewed from the Z direction. Bosses 22 and 27 are provided on each of the side walls 12 facing each other in the communication portion 17. The boss 22 and the boss 27 are located at positions overlapping each other when viewed from the Z direction. Further, bosses 23, 24, 28, and 29 are provided so as to extend toward the outside of the blower case along the peripheral wall 13 of the device housing portion 11, respectively. The boss 23 and the boss 28 and the boss 24 and the boss 29 are located at positions overlapping each other when viewed from the Z direction. Although not shown, the mounting leg 50 and the engaging clips 60 and 61 are provided on both sides of the blower case 10 along the Z direction.
　本変形例によれば、ブロワケース１０の互いに対向する側壁１２，１５にボス２１とボス２６、また、ボス２２とボス２７をそれぞれ設け、または周壁１３の互いに対向する位置にボス２３とボス２８、またボス２４とボス２９とをそれぞれ設けることで、取付脚部５０に対してブロワユニット１００のＺ方向に関する位置安定性を高められる。また、ボスと係合クリップとが係合される箇所を増やすことにより、取付脚部５０がブロワユニット１００を支持する支持強度を高めることができる。 According to the present modification, the boss 21 and the boss 26 and the boss 22 and the boss 27 are provided on the side walls 12 and 15 of the blower case 10 facing each other, or the boss 23 and the boss 28 are provided on the peripheral wall 13 at positions facing each other. By providing the boss 24 and the boss 29, the positional stability of the blower unit 100 with respect to the mounting leg 50 in the Z direction can be enhanced. In addition, by increasing the number of places where the boss and the engagement clip are engaged, the support strength of the mounting leg 50 supporting the blower unit 100 can be increased.
　また、本変形例に示す構成においても、変形例２，３と同様に、一方の側壁側に位置するボスを係合クリップに係合させるようにしてもよい。その場合、ブロワユニット１００の重心、言いかえるとモータ３０の重心に近い側に位置するボスを係合クリップに係合させるのが好ましい。図２に示すように、ブロワケース１０の機器収容部１１の中でモータ３０はＺ方向で一方によって配置されているため、モータ３０により近い側のブロワケース１０の側壁１５に設けられたボスを係合クリップに係合させて取付脚部５０にブロワユニット１００に取付けるようにしてもよい。 Also, in the configuration shown in this modification, similarly to the modifications 2 and 3, the boss located on one side wall may be engaged with the engagement clip. In that case, it is preferable that the boss located on the side closer to the center of gravity of the blower unit 100, in other words, the side close to the center of gravity of the motor 30, be engaged with the engagement clip. As shown in FIG. 2, since the motor 30 is arranged in the device housing portion 11 of the blower case 10 by one side in the Z direction, the boss provided on the side wall 15 of the blower case 10 closer to the motor 30 is removed. The blower unit 100 may be attached to the attachment leg 50 by engaging with an engagement clip.

　図１０Ａは、本変形例に係るブロワケースの側面図を、図１０Ｂは、ブロワケースの別の側面図でそれぞれ示す。なお、図１０Ａは図５に、図１０Ｂは図６にそれぞれ対応している。また、図１０Ａ中に示す矢印Ｉは、係合クリップ６１に対してボス２１が取付けられる方向を示し、図１０Ａ中に示す矢印ＩＩは、係合クリップ６０に対してボス２２が取付けられる方向を示している。同様に、図１０Ｂ中に示す矢印Ｉは、係合クリップ６０に対してボス２４が取付けられる方向を示し、図１０Ｂ中に示す矢印ＩＩは、係合クリップ６１に対してボス２３が取付けられる方向を示している。また、本変形例に示す構成において、ブロワユニット１００を取付脚部５０に取付ける際に、ボス２１又は２４を係合クリップ６１又は６０に係合させてから（矢印Ｉに対応）、ボス２２又は２３を係合クリップ６０又は６１に係合させるようにしている（矢印ＩＩに対応）。 <Modification 5>
FIG. 10A is a side view of a blower case according to this modification, and FIG. 10B is another side view of the blower case. 10A corresponds to FIG. 5, and FIG. 10B corresponds to FIG. An arrow I in FIG. 10A indicates a direction in which the boss 21 is attached to the engaging clip 61, and an arrow II in FIG. 10A indicates a direction in which the boss 22 is attached to the engaging clip 60. Is shown. Similarly, an arrow I shown in FIG. 10B indicates a direction in which the boss 24 is attached to the engaging clip 60, and an arrow II shown in FIG. Is shown. Further, in the configuration shown in this modification, when the blower unit 100 is mounted on the mounting leg 50, the boss 21 or 24 is engaged with the engaging clip 61 or 60 (corresponding to the arrow I), and then the boss 22 or 23 is engaged with the engagement clip 60 or 61 (corresponding to the arrow II).
　実施形態１及び変形例２，３において、係合クリップ６０，６１はＹ方向に延びるように、かつその先端が根元よりもＹ方向上側に位置するように設けられている。係合クリップ６０，６１をこのような配置にすることで、図５～８に示すように、係合クリップ６０，６１に対して２つのボスが取付けられる方向を同じにすることができ、取付脚部５０へのブロワユニット１００の取付け作業が簡素化される。また、取付脚部５０がブロワユニット１００を支持する支持強度を高めることができる。 In the first embodiment and the modified examples 2 and 3, the engaging clips 60 and 61 are provided so as to extend in the Y direction and the tips thereof are located above the root in the Y direction. By arranging the engaging clips 60 and 61 in such a manner, the directions in which the two bosses are attached to the engaging clips 60 and 61 can be made the same as shown in FIGS. The work of attaching the blower unit 100 to the leg 50 is simplified. In addition, the supporting strength of the mounting leg 50 supporting the blower unit 100 can be increased.
　一方、本変形例では、図１０Ａ，１０Ｂに示すように、係合クリップ６０，６１に対して２つのボスが取付けられる方向をそれぞれ異なるようにしている。例えば、図１０Ａに示す構成では、係合クリップ６０は、図５～８に示す構成と同様に、Ｙ方向に延びるように、かつその先端が根元よりもＹ方向上側に位置するように設けられている。また、係合クリップ６０に対してボス２２が取付けられる方向も図５～８に示す構成と同じである。一方、係合クリップ６１は、Ｘ方向に延びるように、かつその先端がＸ方向を向くように設けられており、係合クリップ６１に対してボス２１がＸ方向から取付けられている。また、図１０Ｂに示す構成では、係合クリップ６１は、図５～８に示す構成と同様に、Ｙ方向に延びるように、かつその先端が根元よりもＹ方向上側に位置するように設けられている。また、係合クリップ６１に対してボス２３が取付けられる方向も図５～８に示す構成と同じである。一方、係合クリップ６０は、Ｘ方向に延びるように、かつその先端がＸ方向を向くように設けられており、係合クリップ６０に対してボス２４がＸ方向から取付けられている。 On the other hand, in the present modification, as shown in FIGS. 10A and 10B, the directions in which the two bosses are attached to the engagement clips 60 and 61 are different from each other. For example, in the configuration shown in FIG. 10A, the engaging clip 60 is provided so as to extend in the Y direction and the tip thereof is located above the root in the Y direction as in the configurations shown in FIGS. ing. The direction in which the boss 22 is attached to the engagement clip 60 is also the same as the configuration shown in FIGS. On the other hand, the engaging clip 61 is provided so as to extend in the X direction and the tip thereof is oriented in the X direction, and the boss 21 is attached to the engaging clip 61 from the X direction. Further, in the configuration shown in FIG. 10B, the engagement clip 61 is provided so as to extend in the Y direction and the tip thereof is located above the root in the Y direction as in the configurations shown in FIGS. ing. The direction in which the boss 23 is attached to the engagement clip 61 is also the same as the configuration shown in FIGS. On the other hand, the engaging clip 60 is provided so as to extend in the X direction and the tip thereof is oriented in the X direction, and the boss 24 is attached to the engaging clip 60 from the X direction.
　このように、係合クリップ６０，６１に対して２つのボスが取付けられる方向をそれぞれ異なるようにすることで、取付脚部５０に取付けられたブロワユニット１００に振動が加わった場合に、ボスが係合クリップ６０又は６１から抜けようとする方向を異ならせることができる。このことにより、ボスが係合クリップ６０又は６１から抜けにくくなり、取付脚部５０にブロワユニット１００を取付ける際の安定度が向上する。また、ブロワユニット１００を取付脚部５０に取付ける際に、例えば、図１０Ａに示すように、ボス２１を係合クリップ６１に取付けてから、ボス２２を係合クリップ６０に取付けるため、取付け時の手間は多少増えるが、ボスに対する取付け時の荷重は半分になる。このことにより、取付け時のボスの破損リスクを低減できる。 In this way, by making the directions in which the two bosses are attached to the engagement clips 60 and 61 different from each other, when vibration is applied to the blower unit 100 attached to the attachment leg 50, the bosses are attached. The direction in which the engaging clip 60 or 61 is disengaged can be made different. This makes it difficult for the boss to come off from the engaging clip 60 or 61, and improves the stability when the blower unit 100 is mounted on the mounting leg 50. When attaching the blower unit 100 to the attachment leg 50, for example, as shown in FIG. 10A, the boss 21 is attached to the engagement clip 61, and then the boss 22 is attached to the engagement clip 60. The work is slightly increased, but the load on the boss is reduced by half. This can reduce the risk of breakage of the boss during mounting.
　＜変形例６＞
　図１１Ａは、本変形例に係るブロワケースの側面図を、図１１Ｂは、ブロワケースの別の側面図をそれぞれ示す。なお、図１１Ａは図５に、図１１Ｂは図６にそれぞれ対応している。 <Modification 6>
FIG. 11A is a side view of a blower case according to this modification, and FIG. 11B is another side view of the blower case. 11A corresponds to FIG. 5, and FIG. 11B corresponds to FIG.
　本変形例に示す構成と変形例５に示す構成とでは、係合クリップ６０又は６１が係合フック６４に変更されている点で異なる。係合フック６４は、Ｘ方向に延び、かつその先端がＸ方向を向くように設けられている。図１１Ａ中に示す矢印Ｉは、係合フック６４に対してボス２１が取付けられる方向を示し、図１１Ａ中に示す矢印ＩＩは、係合クリップ６０に対してボス２２が取付けられる方向を示している。同様に、図１１Ｂ中に示す矢印Ｉは、係合フック６４に対してボス２４が取付けられる方向を示し、図１１Ｂ中に示す矢印ＩＩは、係合クリップ６１に対してボス２３が取付けられる方向を示している。また、本変形例に示す構成において、ブロワユニット１００を取付脚部５０に取付ける際に、ボス２１又は２４を係合フック６４に押し付けて係合させてから（矢印Ｉに対応）、ボス２２又は２３を係合クリップ６０又は６１に挿入してこれらを係合させるようにしている（矢印ＩＩに対応）。 構成 The configuration shown in the present modification is different from the configuration shown in Modification 5 in that the engaging clip 60 or 61 is changed to the engaging hook 64. The engagement hook 64 is provided so as to extend in the X direction and have its tip directed in the X direction. An arrow I shown in FIG. 11A indicates a direction in which the boss 21 is attached to the engaging hook 64, and an arrow II shown in FIG. 11A indicates a direction in which the boss 22 is attached to the engaging clip 60. I have. Similarly, the arrow I shown in FIG. 11B indicates the direction in which the boss 24 is attached to the engagement hook 64, and the arrow II shown in FIG. 11B is the direction in which the boss 23 is attached to the engagement clip 61. Is shown. Further, in the configuration shown in this modification, when the blower unit 100 is mounted on the mounting leg 50, the boss 21 or 24 is pressed against the engaging hook 64 to be engaged (corresponding to the arrow I), and then the boss 22 or 23 is inserted into the engagement clip 60 or 61 to engage them (corresponding to arrow II).
　図１１Ａ，１１Ｂに示すように、本変形例によれば、ボス２１又は２４を係合フック６４に押し付けて係合させることで、取付脚部５０に対するブロワユニット１００の取付け位置精度を向上させることができる。図１では示していないが、通常、車両２００内に配置された吸気ダクト及び排気ダクト（いずれも図示せず）にブロワユニット１００が接続されて、蓄電池を冷却する。従って、取付脚部５０に取付けられたブロワユニット１００は、これら排気及び吸気ダクトとの位置合わせを行う必要がある。例えば、図１０Ａ，１０Ｂに示す構成において、ボス２１～２４と係合クリップ６０，６１との間である程度の位置合わせはなされるが、係合クリップ内でボスに遊びがあるため、取付脚部５０に対するブロワユニット１００の取付け位置が所定の位置よりも若干ずれる場合がある。一方、本変形例のように、係合フック６４の内面にボス２１又は２４が当接するようにして取付脚部５０にブロワユニット１００を取付けることで、上記のような遊びが無くなり、取付脚部５０に対するブロワユニット１００の取付け位置精度を向上させることができる。 As shown in FIGS. 11A and 11B, according to the present modification, the boss 21 or 24 is pressed against the engagement hook 64 to engage with the engagement hook 64, thereby improving the attachment position accuracy of the blower unit 100 to the attachment leg 50. Can be. Although not shown in FIG. 1, the blower unit 100 is normally connected to an intake duct and an exhaust duct (both not shown) arranged in the vehicle 200 to cool the storage battery. Therefore, it is necessary for the blower unit 100 attached to the attachment leg 50 to perform alignment with these exhaust and intake ducts. For example, in the configuration shown in FIGS. 10A and 10B, the bosses 21 to 24 and the engaging clips 60 and 61 are aligned to some extent. May be slightly shifted from the predetermined position. On the other hand, by attaching the blower unit 100 to the mounting leg 50 such that the boss 21 or 24 abuts on the inner surface of the engagement hook 64 as in the present modification, the play described above is eliminated, and the mounting leg The mounting position accuracy of the blower unit 100 with respect to 50 can be improved.
　なお、本変形例に示す係合フック６４の形状は、図１１Ａ，１１Ｂに示す形状に限定されない。係合フック６４にボスが押し付けられて、取付脚部５０に対するブロワユニット１００の位置決めがなされるのであれば、係合フック６４の先端は別の形状であってもよい。また、ボスの形状が別の形状、例えば、角柱状であれば、それにあわせて位置決め精度が確保されるように、係合フック６４の先端形状を変更することができる。 The shape of the engagement hook 64 shown in this modification is not limited to the shape shown in FIGS. 11A and 11B. If the boss is pressed against the engagement hook 64 to position the blower unit 100 with respect to the mounting leg 50, the tip of the engagement hook 64 may have another shape. If the shape of the boss is another shape, for example, a prismatic shape, the tip shape of the engagement hook 64 can be changed so that the positioning accuracy is secured accordingly.
　（実施形態２）
　図１２Ａは、本実施形態に係るボスの概要の模式図を、図１２Ｂは、別のボスの概要の模式図をそれぞれ示す。なお、図１２Ａ，１２Ｂにおいて、ブロワケース１０に設けられたボス２１と取付脚部５０に設けられた係合ボス６５と連結部材８０以外の構成要素は図示及びその説明を省略している。 (Embodiment 2)
FIG. 12A is a schematic diagram of a boss according to the present embodiment, and FIG. 12B is a schematic diagram of another boss. 12A and 12B, components other than the boss 21 provided on the blower case 10, the engaging boss 65 provided on the mounting leg 50, and the connecting member 80 are not shown or described.
　実施形態１及び変形例１～６に示す構成では、取付脚部５０に係合クリップ６０，６１や係合リング６２，６３あるいは係合フック６４等の係合部を設け、これら係合部とブロワケース１０に設けられたボス２０～２９のいずれかを係合させて、ブロワユニット１００を取付脚部５０に取付けている。一方、本実施形態では、取付脚部５０の係合部を係合ボス６５とし、ブロワケース１０に設けられたボス２１と係合ボス６５との間を連結部材８０で連結するようにしている。なお、ボス２２～２９の少なくとも一つを連結部材８０を用いて別の係合ボスと係合させることもできる。 In the configuration shown in the first embodiment and the modified examples 1 to 6, engaging portions such as engaging clips 60 and 61, engaging rings 62 and 63, and engaging hooks 64 are provided on the mounting leg portion 50, and these engaging portions are The blower unit 100 is attached to the attachment leg 50 by engaging any one of the bosses 20 to 29 provided on the blower case 10.
