发明内容
发明要解决的课题
再者，两个部件具备管状，在将一方部件的端部插入到另一方部件的筒内并进行接合的情况下，对于专利文献1那样的结构而言，为了避免线材偏移，需要将线材引出到外部并固定。并且，在粘接剂固化后，将线材的露出的多余部分切断。

具体实施方式
参照附图对本发明的第一实施方式详细地进行说明。需要说明的是，在说明中，对相同的要素标注相同的附图标记，并省略重复说明。
本实施方式的粘接构造1用于构成车身(未图示)的副车架100的组装(参照图1、图2)。
副车架100为用于将发动机(未图示)、悬架(未图示)、转向装置(未图示)等支承在车身上的构造体。并且，副车架100架设在沿车辆前后方向延伸的一组侧车架(未图示)之间。
这样的副车架100具备固定于各侧车架的一组托架21和使一组托架21间相连的中心梁11。
并且，本实施方式的粘接构造1用于中心梁11与各托架21的接合(参照图1、图2)。
也就是说，本实施方式的粘接构造1为用于将由中心梁11和托架21构成的一对部件接合为一体的构造。
需要说明的是，一组托架21分别具备同样的构造，因此，为了便于说明，仅对一方进行图示以及说明，省略另一方的图示以及说明。
此外，在图1、图2中，为了易于理解粘接构造1，分别用实线表示托架21，用双点划线表示中心梁11。
中心梁11由碳纤维强化塑料(CFRP：Carbon Fiber Reinforced Plastics)构成，并具备梁主体12和梁侧接合部13(参照图1、图2)。
如图1、图2所示，梁主体12具备截面大致呈五边形的筒形。
梁侧接合部13为连结于托架21的部位且设定在梁主体12的两端部分。并且，梁侧接合部13与后述的托架侧接合部23一起构成粘接构造1。
此外，梁侧接合部13的内周面设定为涂布粘接剂的梁侧接合面14。
在梁侧接合部13的各部分开设有穿插孔16(参照图1、图2)。
穿插孔16中穿插对中心梁11和托架21进行紧固的螺栓(未图示)等。在直至粘接剂固化为止的期间螺栓实施固定，使得中心梁11与托架21不会偏移或脱落。
需要说明的是，如图3所示，在梁侧接合部13的内周面形成有绝缘层15。并且，通过绝缘层15介于CFRP与铝合金之间，来防止电蚀的产生。
托架21由铝合金构成，并具备车身紧固部22和托架侧接合部23(参照图1、图2)。
车身紧固部22为副车架100中的紧固于车身(未图示)的部位。
需要说明的是，在本实施方式中，为了便于说明，省略图示车身紧固部22的形状。
如图1、图2所示，托架侧接合部23为连结于中心梁11的部位，并与所述的梁侧接合部13一起构成粘接构造1。此外，托架侧接合部23能够穿插到梁侧接合部13的筒内，且具备比梁主体12小一圈的截面大致呈五边形的筒形。
托架侧接合部23的外周面涂布有粘接剂，并且设定为与梁侧接合面14对置的托架侧接合面24。
也就是说，对于本实施方式的粘接构造1，在梁侧接合面14与托架侧接合面24之间涂布有粘接剂，通过使粘接剂固化，而对中心梁11和托架21进行接合。
此外，如图1、图2所示，在托架侧接合面24上的各部分以规定的间隔竖立设置有多个突起25。
突起25具备矩形截面(参照图3)，并沿着滑动方向X延伸设置(参照图1、图2)。
需要说明的是，滑动方向X是指向梁侧接合部13的筒内插入(组装)托架侧接合部23时使该托架侧接合部23滑动的方向。
此外，突起25的沿着滑动方向X的尺寸L25被设定为，短于托架侧接合部23的配置有突起25的部位处的沿着滑动方向X的尺寸L23(参照图1、图2)。并且，突起25配置在与接合区域AR1的周缘相比靠内侧的位置。
也就是说，在接合后无法从外部目视观察的位置(未露出于外部的位置)配置有突起25。
需要说明的是，如图1、图2所示，接合区域AR1为，在将托架侧接合部23组装于梁侧接合部13的状态下，梁侧接合面14与托架侧接合面24重叠并利用粘接剂接合的区域。
此外，如图3所示，突起25的高度尺寸H25被设定为，在托架侧接合部23插入到梁侧接合部13的筒内中央的状态下，突起25的顶端与托架侧接合面24抵接。
此外，如图1、图2所示，在多个突起25之中存在开设有操作孔26的突起。
如图4所示，操作孔26由贯穿托架侧接合部23的通孔构成，并配置在突起25的滑动方向X的后方。
对于操作孔26，在将托架21插入至中心梁11后，螺栓(未图示)穿过穿插孔16进行螺合，从而实施滑动方向X上的中心梁11与托架21的定位。
接着，对本实施方式的作用效果进行说明。
对于本实施方式的粘接构造1而言，突起25从托架21(一方部件)朝向中心梁11(另一方部件)以规定的高度尺寸H25突出(参照图3)。
因此，在将托架21插入到中心梁11内时，能够将两接合面的间隔保持在突起25的高度尺寸H25以上。
由此，能够将部件间涂布的粘接剂的厚度保持在突起25的高度尺寸H25以上，因此，消除了由粘接剂的厚度不足引起的粘接不良，能够发挥稳定的粘接力。
此外，本实施方式的粘接构造1为不使用金属线等线材的构造，因此，能够抑制以配置到粘接端部为止的线材为起点而产生的部件间的剥离，并且，能够抑制粘接强度的下降。
而且，通过设置突起25，减少了部件间的空间容积，因此，能够削减价格较高的粘接剂的涂布量，因此，能够削减制造成本。
除此以外，通过设置突起25，能够增大粘接面积，因此，能够提高粘接剂的结合力。
对于本实施方式的粘接构造1而言，突起25沿着组装一对部件(中心梁11、托架21)时的滑动方向X延伸设置。
因此，如图5所示，涂布在某一方接合面上的粘接剂在组装时沿着突起25流动，因此，不会引起因粘接剂不绕到突起25的背面侧而产生的粘接不良。
由此，能够防止粘接不良，能够发挥稳定的粘接力。
需要说明的是，对于本实施方式的粘接构造1而言，如图5所示，操作孔26配置在突起25a与突起25b之间(滑动方向X上的突起25a的后方且突起25b的前方)，但并不限定于这样的位置。
例如，如图6所示，如果是滑动方向X上的突起25的后方，则也可以在操作孔26的后方没有突起。
本实施方式的粘接构造1为突起25未露出在接合区域AR1的周缘的构造。在一对部件的接合部分施加有剪切力或弯曲力时，应力集中于其周缘部分。因此，为了防止部件间的剥离，理想的是粘接力均匀。
对此，对于本实施方式的粘接构造1而言，在不从接合区域AR1的周缘露出的位置配置有突起25，因此，能够使周缘部分的粘接力均匀。
由此，能够抑制以突起25为起点的部件间的剥离，能够不易发生粘接强度的下降。
在本实施方式的粘接构造1的突起25的一部分且在滑动方向X的后方，开设有由通孔构成的操作孔26。通过在这样的位置开设操作孔26，在滑动部件进行组装时，能够抑制粘接剂进入操作孔26。
由此，能够防止由粘接剂无法到达应该涂布的部位而引起的粘接不良。
此外，能够削减进入操作孔26而被浪费的粘接剂，因此，能够削减制造成本。
而且，能够省略为了使粘接剂不进入操作孔26而预先利用夹具进行堵塞等工序，因此，能够改善操作性。
需要说明的是，在本实施方式的粘接构造1中，突起25的截面形状被设定为矩形。
通过设为这样的截面形状，粘接剂更难以绕至突起25的背面侧，粘接剂进入操作孔26的情况进一步得到抑制。
此外，本实施方式的粘接构造1为仅在托架21侧具备突起25的构造，但并不限定于此。
例如，也能够设为仅在中心梁11侧具备突起的构造以及在中心梁11侧和托架21侧这两方具备突起的构造。
即使在设为这些构造的情况下，也能够获得与本实施方式同样的作用效果。
而且，本实施方式用于复合材料(CFRP)与金属(铝合金)的粘接构造，但并不限定于这样的组合。
例如，也能够应用于金属间以及复合材料间的组合的粘接构造，获得同样的作用效果。
接着，参照附图对本实施方式的第一其他方式详细地进行说明。需要说明的是，在说明中，对与前述实施方式相同的要素标注相同的附图标记，并省略重复说明。
如图7所示，对于本方式与前述实施方式，不同的构造是突起25A的形状。
本方式的突起25A具备截面形状为尖细的大致三角形。
需要说明的是，在托架侧接合面24上沿着滑动方向X延伸设置有突起25A这一点以及接合后在不向外部露出的部位配置有突起25A这一点，与前述实施方式相同。
接着，对本方式的作用效果进行说明。
对于本方式的粘接构造1而言，突起25A的截面形状成为大致三角形，从而粘接剂易于绕至突起25A的背面侧。
由此，粘接剂的涂布不匀得以降低，粘接构造1能够发挥更强的结合力。
此外，通过将突起25A的截面形状设为尖细的大致三角形，突起25A的顶端与梁侧接合面14的接触成为线接触。
由此，不会缩小梁侧接合面14(另一方接合面)涂布有粘接剂的面积，因此，粘接构造1能够发挥更强的结合力。
接着，参照附图对本实施方式的第二其他方式详细地进行说明。需要说明的是，在说明中，对与前述实施方式相同的要素标注相同的附图标记，并省略重复说明。
如图8所示，对于本方式与前述实施方式，不同的构造为突起25B的形状。
本方式的突起25B独立于托架21而由其他部件构成，且由在CFRP与铝合金之间不会发生电蚀的树脂材料形成。此外，突起25B具备尖细的大致圆锥形。并且，突起25B在圆锥形的底面部具备压入突部27。
通过将这样的压入突部27压入由形成在托架侧接合面24上的凹部构成的突起承接孔(未图示)，突起25B被固定在托架侧接合面24上。
接着，对本方式的作用效果进行说明。
对于本方式的粘接构造1而言，突起25B的截面形状为大致圆锥形，从而粘接剂易于绕至突起25B的背面侧。
由此，粘接剂的涂布不匀得以降低，粘接构造1能够发挥更强的结合力。
此外，通过将突起25B的截面形状设为大致圆锥形，突起25B的顶端与梁侧接合面14的接触成为点接触。
由此，不会缩小梁侧接合面14(另一方接合面)涂布有粘接剂的面积，因此，粘接构造1能够发挥更强的结合力。
需要说明的是，在本方式中，作为尖细形状的突起，例示了截面大致呈三角形的突起25A以及圆锥形的突起25B，但并不限定于此。
例如，如图9所示，也能够设为半球状的突起25C。
通过设为这样的形状，与圆锥形等相比顶端不易被压溃，因此，易于进行部件的管理。
