ｂとする直円筒８を設けてある。 As shown in FIG. 1, the peripheral edge of the opening of the oil filler pipe 1 of the fuel tank is slightly enlarged to form a large diameter portion 2,
An annular raised part 3 is formed by bending horizontally outward from the upper end of the large diameter part 2, has a required width in the radial direction, and has an upper surface as a sealing surface 3a. An annular hanging wall part 4 is formed by bending downward at a right angle, and an annular low step part 5 is formed by bending horizontally outward from the lower end of the annular hanging wall part 4, following the annular high step part 3. The annular hanging wall 6 is bent downward from the outer periphery of the annular low step part 5 at a substantially right angle, and the lower surface of the annular lower edge 7 is bent horizontally inward from the lower end of the annular hanging wall 6. The part formed on the contact part 7a, whose lower outer periphery is fixed to the inner peripheral surface of the large diameter part 2, and which projects upward from the annular high step part 3 is a cylindrical barrier part 8a, and the upper end opening is a fuel filler port 8.
A right cylinder 8 designated b is provided.

屈曲する環縁１６を形成してある。 As shown in FIG. 1, the cap 9 attached to the oil filler port 1 has a circumferential groove-like portion 13 around the central high portion 12 of a cap-shaped suppressor 11 provided inside the cap body 10.
A coil spring 14 is provided with one end fixed to the top plate part 10a of the cap body 10 and the other end fixed to the inner surface of the top plate part 10a of the cap body 10, and whose lower part is surrounded by the central high part 12. An annular packing 15 is fixed thereto, and an inwardly bent annular edge 16 is formed at the lower end of the cap body 10.

せるように形成してある。 When the cap 9 is attached to the oil supply pipe 1,
The annular packing 15 fixed to the cap-shaped suppressor 11 is brought into pressure contact with the sealing surface 3a of the annular raised portion 3 of the oil filler pipe 1 by the elastic force of the coil spring 14, and the oil filler port 8b is placed in the central high place. The inner surface of the annular edge 16 is formed so as to be covered by the ring 12 and in close contact with the abutting part 7a.

内に砂、塵埃が侵入することはない。 Since the device of the present invention is configured as described above, when the cap 9 is removed from the oil supply pipe 1, the sand, dust, etc. accumulated on the annular low step part 5 due to vibration etc. will exceed the vertical wall part 4 and the annular Cylindrical barrier portion 8a that protrudes upward from the annular high step portion 3 even if it rides on the sealing surface 3a of the high step portion 3 and moves toward the fuel filler port 8b.
Since it does not exceed the oil supply port 8b, the oil supply pipe 1
No sand or dust can enter inside.
