Claim:
1. A liquid-level detection device for detecting a level of a surface of liquid stored in a container, comprising: a float that floats on the surface of liquid; a rotatable body that rotates due to an upward or downward displacement of the float and includes a rotation contact part; a supporting body that rotatably supports the rotatable body and includes a supporting contact part which is located on a rotational track of the rotation contact part to restrict the rotation of the rotatable body in a specified direction by contact between the supporting contact part and the rotation contact part; and an attachment member that is attached to the supporting body and includes an attachment contact part which makes contact with the rotatable body rotating in the specified direction to prevent the contact of the rotation contact part with the supporting contact part, wherein: a position of the rotation contact part of the rotatable body is capable of being chosen between a first position, and a second position that is shifted from the first position in a radial direction of the rotatable body; the supporting body includes: when the second supporting contact part is damaged, the rotation contact part arranged at the second position is displaced beyond the damaged second supporting contact part in the specified direction, so that the attachment contact part makes contact with the rotatable body.
