The present invention provides a technique of reducing the dimensions of a body having a rotation regulation portion of an arm. A fuel amount detection apparatus comprises: a holder (34) which is fixed to an arm (24) mounted on a float; and a body (32) which supports the holder (34) to rotate. The body (32) includes rotation regulation portions (R1 to R32). The holder (34) is supported to the body (32) in a state where a range of a rotation angle of the arm (24) is regulated by any rotation regulation portion of the rotation regulation portions (R1 to R32). A rotation angle range (AR1) is different from a rotation angle range (AR21) in magnitude of angle, and is not overlapped with the rotation angle range (AR21) in a rotation direction (RD) of the arm (24). Each of the rotation regulation portions (R1 to R32) includes a pair of stop portions which stop the rotation of the arm (24). In each of the rotation regulation portions (R1 to R32), at least a part between the pair of stop portions of the rotation regulation portion is opened outwards. |
