Engine oil filling device

Abstract

An engine oil filling device includes: an oil filling pipe attached at a lower end side of the device to an oil supply port that communicates with an oil pan, and provided at an upper end side of the device with an oil receiving part that opens upwardly; a cap that is provided with a cylinder part that protrudes inside the cap, an oil level gauge attached to the cylinder part and inserted from the oil filling pipe into the oil pan via the oil supply port, covers the oil receiving part, and is fixed to the oil filling pipe by being rotated and a sealing member that is provided inside the cap and is rotatable about the axis of the oil level gauge, and seals between an inner circumferential surface of the oil filling pipe below the oil receiving part and an outer circumferential surface of the cylinder part.

1 . An engine oil filling device, comprising:
 an oil filling pipe attached at a lower end side thereof to an oil supply port that communicates with an oil pan, and provided at an upper end side thereof with an oil receiving part that opens upwardly;   a cap provided with a cylinder part that protrudes inside the cap, an oil level gauge that is attached to the cylinder part and inserted from the oil filling pipe into the oil pan via the oil supply port, and the cap covering the oil receiving part of the oil filling pipe and being fixed to the oil filling pipe by being rotated; and   a sealing member that is provided inside the cap so as to be rotatable about an axis of the oil level gauge, and seals between an inner circumferential surface of the oil filling pipe below the oil receiving part and an outer circumferential surface of the cylinder part of the cap.   
     
     
         2 . The engine oil filling device of engine oil of  claim 1 , wherein the oil receiving part is formed in a gutter shape that opens upwardly. 
     
     
         3 . The engine oil filling device of  claim 1 ,
 wherein the sealing member has a larger diameter part that seals the inner circumferential surface of the oil filling pipe below the oil receiving part, and a smaller diameter part that seals the outer circumferential surface of the cylinder part of the cap, and   wherein, when the cap is rotated, the cylinder part is slidingly rotated while contacting the smaller diameter part, without the larger diameter part rotating with respect to the inner circumferential surface of the oil filling pipe below the oil receiving part.   
     
     
         4 . The engine oil filling device of  claim 2 ,
 wherein the sealing member has a larger diameter part that seals the inner circumferential surface of the oil filling pipe below the oil receiving part, and a smaller diameter part that seals the outer circumferential surface of the cylinder part of the cap, and   wherein, when the cap is rotated, the cylinder part is slidingly rotated while contacting the smaller diameter part, without the larger diameter part rotating with respect to the inner circumferential surface of the oil filling pipe below the oil receiving part.   
     
     
         5 . The engine oil filling device of  claim 1 ,
 wherein at least one protruded portion is provided on an outer circumferential part of the oil filling pipe, the protruded portions protruding radially and being storable inside the cap, and   wherein at least one slot is formed in the cap to engage with the at least one protruded portion by rotation of the cap.   
     
     
         6 . The engine oil filling device of  claim 2 ,
 wherein at least one protruded portion is provided on an outer circumferential part of the oil filling pipe, the protruded portions protruding radially and being storable inside the cap, and   wherein at least one slot is formed in the cap to engage with the at least one protruded portion by rotation of the cap.   
     
     
         7 . The engine oil filling device of  claim 3 ,
 wherein at least one protruded portion is provided on an outer circumferential part of the oil filling pipe, the protruded portions protruding radially and being storable inside the cap, and   wherein at least one slot is formed in the cap to engage with the at least one protruded portion by rotation of the cap.   
     
     
         8 . The engine oil filling device of  claim 4 ,
 wherein at least one protruded portion is provided on an outer circumferential part of the oil filling pipe, the protruded portions protruding radially and being storable inside the cap, and   wherein at least one slot is formed in the cap to engage with the at least one protruded portion by rotation of the cap.
