即，用于将线圈端子与连接端子连接的连接空间需要规定的宽度(连接方向的长度)。因此，例如在旋转电机的壳体的外周部设置连接空间的情况下，该壳体的宽度成为规定值以上的大小，动力产生装置整体的轴向或径向的尺寸大型化。

在上述(5)的情况下，防止了连接空间与旋转电机的定子及转子在从半径方向观察时在轴向上重叠的情况，能够抑制旋转电机的径向的尺寸的大型化。
在上述(6)的情况下，能够通过窗部进入连接空间，因此能够容易将线圈端子与供电线缆的连接端子连接。
在上述(7)的情况下，将连接空间形成在比排热系统位置低的位置，因此能够抑制供电线缆从排热系统部件受到的热量的作用。
在上述(8)的情况下，即使在连接空间形成于下部缸体的情况下，也能够防止连接部沾水的情况。
在上述(9)的情况下，旋转电机不需要专用的壳体，能够削减部件数量。

具体实施方式
以下，参照附图，对本发明的一实施方式的动力产生装置进行说明。
如图1所示，本实施方式的动力产生装置10搭载于混合动力车辆1。如图1～图3所示，动力产生装置10具备：内燃机(ENG)11；在内燃机11的曲轴(省略图示)的轴向上与内燃机11相邻配置的旋转电机(MOT)12；以及在内燃机11的轴向上与旋转电机12相邻配置的变速器(T/M)13。内燃机11及变速器13配置成从内燃机11的轴向的两侧夹入旋转电机12。旋转电机12的旋转轴(省略图示)在轴向的两端部与内燃机11的曲轴(省略图示)和变速器13的输入轴(省略图示)连结。
需要说明的是，在图1所示的混合动力车辆1中，例如将后轮作为驱动轮，变速器13的输出轴(省略图示)与后轮连结。动力产生装置10在混合动力车辆1的前后方向上，配置在比电力设备(IPU)14靠后方侧的位置，该电力设备14具备作为对旋转电机12通电的电源的蓄电装置及电力转换装置等。在动力产生装置10中，使内燃机11的轴向与车辆前后方向平行，从前方侧朝向后方侧依次排列内燃机11、旋转电机12及变速器13。
如图4～图8所示，内燃机11具备发动机缸体(气缸体)21，该发动机缸体21例如为V型6气缸，包括一对上部缸体21a及下部缸体21b和气缸盖21c。发动机缸体21具备由上部缸体21a及下部缸体21b形成的曲轴(省略图示)的插通部22。气缸盖21c安装于上部缸体21a的上部，与上部缸体21a一起构成收容活塞(省略图示)的气缸(省略图示)。如图7～图9所示，发动机缸体21具有与旋转电机12的壳体结构体31的接合面31A接触的接合面21A，在该接合面21A与壳体结构体31的接合面31A接触的状态下进行螺栓紧固等，从而发动机缸体21与旋转电机12的壳体结构体31接合。
如图4及图9所示，旋转电机12具备壳体结构体31、定子32及转子33。壳体结构体31与内燃机11的发动机缸体21接合且保持定子32。如图9及图10所示，定子32具备配置成圆环状的多个定子片35、在多个定子片35上分别卷绕的线圈36。定子32具备保持环37。保持环37通过压入多个定子片35而保持多个定子片35的外周部，并且通过螺栓紧固等固定于壳体结构体31。转子33配置于定子32的径向内侧，在半径方向上与定子32对置，并且同轴地固定于内燃机11的曲轴(省略图示)的端部。
旋转电机12例如为三相的无刷DC电动机。如图10所示，定子32具备绝缘构件41、连接构件42及配电部件43。绝缘构件41在定子32的轴向上，且在变速器13侧的端部32a以使三相的线圈36的各线圈每相绝缘的状态沿周向配置。连接构件42与由绝缘构件41保持的三相的线圈36的各自的端部(线圈端)连接，且在定子32的径向外侧(例如，上下方向的上部)的位置沿轴向朝向内燃机11侧的端部32b延伸。配电部件43与三相的连接构件42分别连接，如图9所示，具备在定子32的径向外侧的位置沿周向从上部朝向下部延伸的配线部43a、与各配线部43a的前端部连接的端子部43b。如图8所示，配电部件43以端子部43b在内燃机11的轴向上向设置于发动机缸体21的连接空间51内突出的方式固定于发动机缸体21的内部。
需要说明的是，如图10所示，在旋转电机12的轴向上，壳体结构体31的外周部的轴向长度形成为比定子32的轴向长度短，定子32及转子33的轴向的一部分配置成至少向变速器13或内燃机11的发动机缸体21的内部空间内突出。
另外，如图8所示，在内燃机11的轴向上比转子33靠内燃机11侧的位置，用于检测旋转电机12的旋转角的解析器45固定于发动机缸体21的内部。
如图5所示，在形成内燃机11的发动机缸体21的一对上部缸体21a及下部缸体21b中的例如下部缸体21b上，在轴向上的旋转电机12侧的端部，插通部22的外周面22A的一部分向径向外侧鼓出而形成鼓出部52。鼓出部52使具有比壳体结构体31小的外径的插通部22的外周面22A的一部分鼓出至与壳体结构体31的外周面31B连续。如图8所示，在该鼓出部52设有连接空间51，该连接空间51用于将旋转电机12的配电部件43的各端子部43b与外部的电力设备14的供电线缆61的各连接端子62连接。
鼓出部52在从内燃机11的轴向观察时，形成在比插通部22靠径向外侧、且比内燃机11的发动机缸体21与旋转电机12的壳体结构体31接合的接合面21A的外缘靠径向内侧的位置。
连接空间51配置于在内燃机11的轴向上与旋转电机12的定子32及转子33错开的位置。即，连接空间51与旋转电机12的定子32及转子33配置成，在从半径方向观察时在轴向上不重叠。
在形成连接空间51的下部缸体21b的鼓出部52的内部设有配电部件固定部53，该配电部件固定部53用于通过螺栓紧固等将旋转电机12的配电部件43的各端子部43b的支承构件43c固定。另外，如图5所示，在鼓出部52设有供电线缆固定部54，该供电线缆固定部54面临在配电部件固定部53上固定的端子部43b且在轴向的前方侧开口，并且用于通过螺栓紧固等将供电线缆61固定。由此，供电线缆61在内燃机11的周围沿轴向配置，并且沿着内燃机11的轴向向连接空间51内插入。并且，在配电部件固定部53上固定的各端子部43b与在供电线缆固定部54上固定的供电线缆61的各连接端子62在连接空间51内电连接。
如图11～图14所示，鼓出部52具备窗部55，该窗部55在径向上与连接部52a对置的外侧的部位开口，该连接部52a为各端子部43b与供电线缆61的各连接端子62的连接部。由此，各端子部43b与供电线缆61的各连接端子62例如通过基于从窗部55插入的螺栓63的螺栓紧固等来固定。
需要说明的是，如图14所示，配电部件43的各端子部43b的支承构件43c具有装配密封构件43d的密封槽43e，通过该密封构件43d对配电部件固定部53与支承构件43c之间进行液密性地密封。另外，在供电线缆固定部54上固定的供电线缆61的前端部61a具备装配密封构件61b的密封槽61c，通过该密封构件61b对供电线缆固定部54与供电线缆61的前端部61a之间进行液密性地密封。另外，在配电部件43的各端子部43b与供电线缆61的各连接端子62被固定后，窗部55能够通过将该窗部55液密性地闭塞的盖体64(密封构件)来封闭。由此，连接空间51相对于外部密闭。
如上述那样，根据本实施方式的动力产生装置10，连接空间51形成于内燃机11的一部分，因此能够抑制动力产生装置10的轴向的尺寸的大型化。
即，用于将配电部件43的各端子部43b与供电线缆61的各连接端子62连接的连接空间51需要规定的宽度(连接方向的长度或通过工具等进入连接空间51的方向的长度)。因此，例如在旋转电机12的壳体结构体31的外周部设置连接空间51的情况下，该壳体结构体31的宽度成为规定值以上的大小，动力产生装置10整体的轴向或径向的大小大型化。
与此相对，通过将连接空间51形成于内燃机11的一部分，能够有效地利用内燃机11侧的空间来设置连接空间51，能够抑制旋转电机12的壳体结构体31的大型化。
例如，在旋转电机12的壳体结构体31中，轴向的剖面成为圆形状，因此需要将连接空间51设置在壳体结构体31的外周部或轴向的端部，从而必然会使径向或轴向的尺寸增大。与此相对，在内燃机11的发动机缸体21中，轴向的剖面不是圆形状，在旋转电机12的壳体结构体31的比径向的外缘靠内侧的区域存在能够配置连接空间51的空间的情况下，能够有效地利用该空间来配置连接空间51。
特别是能够利用内燃机11的曲轴的插通部22的周围存在的空间中的、因插通部22与旋转电机12的壳体结构体31的外径的不同而存在的空间来形成连接空间51，因此能够抑制内燃机11及旋转电机12的径向的尺寸的大型化。
而且，能够在内燃机11的周围沿轴向配置供电线缆61，因此与例如沿径向配置供电线缆61的情况相比，能够抑制连供电线缆61也包含在内的动力产生装置10的大型化。
而且，防止了连接空间51与旋转电机12的定子32及转子33在从半径方向观察时在轴向上重叠的情况，能够抑制旋转电机12的径向的尺寸的大型化。
而且，能够通过窗部55进入连接空间51，能够容易将配电部件43的各端子部43b与供电线缆61的各连接端子62连接及固定。
而且，在内燃机11的排热系统部件配置于发动机缸体21的上部缸体21a侧的情况下，连接空间51设置于下部缸体21b，因此能够抑制供电线缆61从排热系统部件受到的热量的作用。
而且，连接空间51相对于外部被液密性地密闭，因此能够防止配电部件43的各端子部43b与供电线缆61的各连接端子62的连接部沾水的情况。
需要说明的是，在上述的实施方式中，将连接空间51设置于下部缸体21b，但没有限定于此，也可以将连接空间51设置于上部缸体21a等发动机缸体21的适当的位置。
(变形例)
需要说明的是，在上述的实施方式中，也可以省略旋转电机12的壳体结构体31，能够通过发动机缸体21来保持定子32。
例如，图15～图17所示的上述的实施方式的变形例的动力产生装置10的内燃机11的发动机缸体21具备在插通部22的轴向上从旋转电机1两侧的端部突出而能够收容定子32及转子33的旋转电机收容部71。在这种情况下，变速器13在内燃机11的轴向上与发动机缸体21的旋转电机收容部71相邻配置。
旋转电机收容部71具备与上部缸体21a及下部缸体21b分别一体地设置的上部收容部71a及下部收容部71b。通过螺栓紧固等将保持多个定子片35的保持环37固定于旋转电机收容部71的内部，由此在该旋转电机收容部71中收容的旋转电机12固定于发动机缸体21。旋转电机12在保持三相的线圈36的绝缘构件41朝向内燃机11侧的状态下，使与三相的线圈36各自的端部(线圈端)连接的连接构件42向定子32的径向外侧(例如，上下方向的上方)突出。由此，在旋转电机收容部71中收容的旋转电机12使各连接构件42向在发动机缸体21的上部收容部71a中设置的连接空间81内突出。
在形成旋转电机收容部71的上部收容部71a及下部收容部71b中的例如上部收容部71a上，在轴向上的变速器13侧的端部，插通部22的外周面22A的一部分向径向外侧(例如，上下方向的上方)鼓出而形成鼓出部82。在该鼓出部82中形成有能够收容旋转电机12的各连接构件42的连接空间81。形成连接空间81的鼓出部82设有供电线缆固定部83，该供电线缆固定部83面临在旋转电机收容部71中固定的旋转电机12的各连接构件42且在轴向的后方侧(即，变速器13侧)开口，并且用于通过螺栓紧固等将供电线缆61固定。由此，供电线缆61在变速器13的周围沿轴向配置，并且沿变速器13的轴向向连接空间81内插入。并且，旋转电机12的各连接构件42和在供电线缆固定部83固定的供电线缆61的各连接端子62在连接空间81内电连接。
鼓出部82具备窗部(省略图示)，该窗部在径向上与连接部对置的外侧的部位开口，该连接部为旋转电机12的各连接构件42与供电线缆61的各连接端子62的连接部。由此，旋转电机12的各连接构件42与供电线缆61的各连接端子62例如通过基于从窗部插入的螺栓(省略图示)的螺栓紧固等来固定。该窗部能够通过盖体84闭塞。
根据该变形例，旋转电机12不需要专用的壳体，旋转电机12所需的各种传感器等的安装直接在发动机缸体21上进行，将旋转电机12的壳体的功能集中于发动机缸体21，由此能够削减部件数量。而且，能够抑制与内燃机11连接的旋转电机12中需要特别的结构的情况，能够在不同类型的内燃机11中促进旋转电机12的共用化。并且，能够提高动力产生装置10的刚性。另外，还能够通过对内燃机11进行冷却的冷却介质来进行旋转电机12的冷却，能够简化内燃机11及旋转电机12的冷却所需的结构。
上述的实施方式是作为例子而提示的实施方式，并没有意图限定发明的范围。上述的新的实施方式能够以其他各种方式实施，在不脱离发明的主旨的范围内能够进行各种省略、置换、变更。
例如，在上述的实施方式中，使搭载有动力产生装置10的混合动力车辆1的驱动轮为后轮，但没有限定于此，也可以使前轮为驱动轮。
另外，在上述的实施方式中，动力产生装置10中与车辆前后方向平行地排列有内燃机11、旋转电机12、变速器13，但没有限定于此，也可以与车辆左右方向等适当的方向平行地排列。
