Abstract
Official abstract text for this publication.
A liquid fuel level sensing device disclosed herein may include: a holder; an arm fixed to the holder; a cover fixed to the holder to cover the arm; and a float connected to the arm outside the holder. The holder may include a bottom portion and a first snap fit structure, which may include a pair of support portions provided with an interval therebetween, and provided on the bottom portion. First and second interval portions may be provided between the pair of support portions, the first interval portion may hold the arm, and the second interval portion may be provided above the first interval portion and be narrower than a width of the arm held in the first interval portion. The cover may include a deformation restricting portion provided at a position facing an outer surface of at least one of the pair of support portions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A liquid fuel level sensing device configured to sense a level of liquid fuel in a fuel tank, the fuel level sensing device comprising: a body configured to be fixed in the fuel tank; a holder rotatably supported by the body; an arm fixed to the holder; a cover detachably fixed to the holder so as to cover the arm; and a float connected to the arm outside the holder, wherein the holder comprises a bottom portion and a first snap fit structure, the first snap fit structure comprises a pair of support portions provided with an interval therebetween, the pair of support portions being provided on the bottom portion, a first interval portion and a second interval portion are provided between the pair of support portions, the first interval portion holding the arm, the second interval portion being provided above the first interval portion, and the second interval portion being narrower than a width of the arm held in the first interval portion, and the cover comprises a deformation restricting portion provided at a position facing an outer surface of at least one of the pair of support portions. 2. The liquid fuel level sensing device of claim 1 , wherein the cover comprises a through hole, and the first snap fit structure is inserted in the through hole. 3. The liquid fuel level sensing device of claim 1 , wherein the cover and the holder comprise a second snap fit structure configured to fix the cover and the holder to each other. 4. The liquid fuel level sensing device of claim 1 , wherein the at least one of the pair of support portions is sandwiched between the arm and the deformation restricting portion. 5. The liquid fuel level sensing device of claim 1 , wherein when the at least one of the pair of support portions is deformed in a direction expanding the second interval portion, the at least one of the support portions comes to contact the deformation restricting portion. 6. The liquid fuel level sensing device of claim 1 , wherein the deformation restricting portion restricts the deformation of the at least one of the pair of support portions.
