The present invention provides a container with a functional member and a tire, which can suppress the generation of cracks on protrusions formed on the inner surface of the container by elaborately designing the internal shape of the container for containing the functional member, and enable the functional member to accurately acquire tire internal information. A storage body with a functional member is provided with a functional member (20) for acquiring tire information and a storage body (10) for storing the functional member (20), the functional member (20) having a housing (21) and a piezoelectric element (24) fixed to a wall surface of the housing (21), and a protrusion (15) formed on an inner surface of the storage body (10). In a non-loaded state and a state in which the functional component (20) is housed in the housing body (10), the protrusion (15) is in direct contact with the piezoelectric element (24) or in indirect contact with the piezoelectric element (24) via a wall surface of the case (21), and in a plan view of the protrusion (15), the area of the bottommost surface (15y) of the protrusion (15) is larger than the area of the topmost surface (15x) of the protrusion (15). The outer edge of the topmost portion (15x) of the protrusion (15) is located on the inner side of the outer edge of the bottommost surface (15y) of the protrusion (15).
本发明提供一种带功能部件的收容体及轮胎,其通过对收容功能部件的收容体的内部形状进行精心设计,以抑制收容体内表面上所形成的突起产生裂纹,并且使功能部件能够准确地获取轮胎内部信息。一种带功能部件的收容体,其具备用于获取轮胎信息的功能部件(20)和收容该功能部件(20)的收容体(10),功能部件(20)具有壳体(21)、以及固定在该壳体(21)的壁面上的压电元件(24),在收容体(10)的内表面上形成有突起(15),在无负载状态且功能部件(20)被收容于收容体(10)中的状态下,突起(15)与压电元件(24)直接接触或隔着壳体(21)的壁面而间接接触,在突起(15)的俯视图中,突起(15)的最底面(15y)的面积大于突起(15)的最顶部(15x)的面积,并且突起(15)的最顶部(15x)的外缘位于突起(15)的最底面(15y)的外缘的内侧。
