Claims

[Claims for Utility Model Registration] In a fuel pump device in which a rotary pump P and an electric motor M for operating the rotary pump P are housed in a housing 22 having a fuel suction port 25a at one end and a fuel discharge port 63a at the other end, The housing 22 includes a cylindrical housing body 23 with one end open, and first and second bearing members 30□ fitted therein. 30□, the vicinity of the opening of the housing body 23 is formed into a large diameter portion 28, and the housing body 2
The inner surface of the end wall of No. 3 and the stepped surface of the inner end of the large diameter portion 28 are perpendicular to the center line of the housing body 23, and
A casing 51 of the rotary pump P is formed on the inner end surface of the first bearing member 301, and is formed at first and second flat surfaces 290 and 29° that abut the bearing member 30□ and the second bearing member 30□, respectively. Both ends of the rotor shaft 36 of the electric motor M, which are fixed and pass through the casing 51, are connected to the first and
The rotary pump P is rotatably supported in the bearing holes 3'L and 34□ of the second bearing members 30□ and 30□, respectively.
A stop ring is provided on a portion of the rotor shaft 36 protruding from both inner end surfaces of the casing 51 and the second bearing member 30° to restrict the axial movement of the rotor shaft 36. 73. ．． A fuel pump device characterized in that 73□ are fitted respectively.
