A spring hook structure includes: a torsion coil spring (30) including a coil portion (31) and a first arm (32) and a second arm (33) extending from each side of the coil portion (31); and a rotation support pin (14) by which a cap (20) is rotatably supported on an exterior case (10). The rotation support pin (14) is inserted into the coil portion (31). The first arm (32) is hooked on a first hook surface (16) of the exterior case (10), and the second arm (33) is hooked on a second hook surface (26) of the cap (20). At least one of the exterior case (10) and the cap (20) is provided with a regulation wall (17, 27) at a position not interfering with the arm (32, 33) moving along the hook surface (16, 26) due to flexural deformation of the coil portion (31) but interfering with the arm (32, 33) moving along the hook surface (16, 26) due to flexural deformation of the arm (32, 33). |
