Description

In other words, if the flexible substrate is bent at the connection point between the detection unit and the signal line unit, a force may act on the detection unit that causes it to lift away from the inner cylindrical part of the holder, based on the elastic force of the bent portion trying to return to its original shape. The supported plate portion 79 is configured in a roughly rectangular flat plate shape. The supported plate portion 79 is coupled and fixed to the other side of the connector body 78, which is one of the four sides of the connector body 78. Furthermore, when implementing this disclosure, various structures can be adopted, not limited to the structure in this example, as long as the connector can be supported by the cover. Specifically, for example, the connector can be supported by screws or the like to the support plate portion of the cover. The ring-side cylindrical portion 70 is positioned around the detection portion 41. In this example, the ring-side cylindrical portion 70 has a small-diameter portion 73 on the other axial side and a large-diameter portion 74 at one end on the axial side, with a larger outer diameter than the small-diameter portion 73. That is, the ring-side cylindrical portion 70 has a stepped cylindrical outer surface, formed by connecting the outer surface of the small-diameter portion 73 and the outer surface of the large-diameter portion 74 with a stepped surface 75 facing the other axial side. In contrast, the inner surface of the small-diameter portion 73 and the inner surface of the large-diameter portion 74 are located on the same cylindrical surface. Therefore, the radial thickness of the large-diameter portion 74 is greater than the radial thickness of the small-diameter portion 73. However, the axial length of the outer cylinder can be made shorter or longer than the axial length of the large-diameter section.
