9. An operation force transmitting member according to claim 1 , wherein the lower end of said cover member is wider than said upper face of said elastic cap member.

10. An operation force transmitting member according to claim 1 , wherein said cover member includes an upper end in which the upper end of said cover member is located further from said door lock apparatus than the lower end of said cover member.

11. An operation force transmitting member which connects a door lock apparatus to an operating device for operating said door lock apparatus at both end portions thereof, said operation force transmitting member comprising:

a guide tube;

an inner cable passed through said guide tube;

an elastic cap member covering an upper end portion of said guide tube; and

a cover member attached on said inner cable at a portion which projects from an upper face of said elastic cap member,

wherein an outer diameter of said cover member is larger than an inner diameter of said guide tube, and

said cover member covers said upper face of said elastic cap member during non-operation of said operating device, said cover member being in contact with said upper face of said elastic cap member during non-operation of said operating device,

where in a lower end of said cover member abuts against said upper face of said elastic cap member to thereby close said upper face of said elastic cap member, and wherein said lower end of said cover member is wider than said upper face of said elastic cap member.

12. An operation force transmitting member according to claim 11 , wherein said cover member closes said upper face of said elastic cap member during non-operation of said operating device.

13. An operation force transmitting member according to claim 11 , wherein said cover member is shaped like an umbrella.

14. An operation force transmitting member according to claim 11 , wherein said cover member has an umbrella shape.

15. A door lock system comprising:

a door lock apparatus;

an operating device for operating said door lock apparatus; and

an operation force transmitting member connecting said door lock apparatus to said operating device at both end portions thereof, said operation force transmitting member including:

a guide tube,

an elastic cap member covering an upper end portion of said guide tube,

an inner cable passed through said guide tube, and

a cover member attached on said inner cable at a portion which projects from an upper face of said guide tube, a lower end of said cover member having a round shape, the lower end of said cover member facing the upper face of said guide tube,

wherein an outer diameter of said cover member is larger than an inner diameter and an outer diameter of said guide tube,

said cover member covers an upper face of said elastic cap member during non-operation of said operating device, in which said door lock apparatus is in an engaged state, said cover member being in contact with said upper face of said elastic cap member during non-operation of said operating device, and

said cover member is spaced apart from said elastic cap member during operation of said operating device, in which said door lock apparatus is in a disengaged state.

16. A door lock system according to claim 15 , wherein said cover member has an umbrella shape.

17. A door lock system according to claim 15 , wherein a lower end portion of the guide tube is connected to the door lock apparatus.

18. A door lock system according to claim 15 , wherein the operating device is disposed above the door lock apparatus.

19. An operation force transmitting member which connects a passenger door lock apparatus of a vehicle to an operating device for operating said passenger door lock apparatus at both end portions thereof, said operation force transmitting member comprising:
