Abstract
An annular groove is formed in a cap body of a cap. An elongated coupling member has a ring part formed integrally therewith, and is coupled to the cap as the ring part is engaged in the annular groove. The cap and the coupling member are each formed of electroconductive resin, and the surface resistance from the cap to the vehicle is set to be greater than or equal to 1×1012 Ω and less than 5.30×1012 Ω. Hence, when the human body is brought into contact with the cap, static electricity in the human body is discharged to the vehicle side, and no shock is imparted to the human body. In addition, the amount of residual charge also declines without causing secondary spark discharge.
Claims20
A string-attached cap comprising:
- a capping member formed of a first electroconductive resin;
- and
- an elongated coupling member having one end connected to said capping member, said elongated coupling member being formed of a second electroconductive resin and being flexible, and said string-attached cap being used with another end of said coupling member coupled to a vehicle,
- wherein said first electroconductive resins and said second electroconductive resin are formed such that surface resistance from said capping member to said vehicle is set to be greater than or equal to 1×1012 Ω and less than 5.30×1012 Ω.
A string-attached cap comprising:
- a capping member formed of a first electroconductive resin;
- an elongated coupling member formed of a second electroconductive resin and being flexible;
- and
- a fastening member formed of a third electroconductive resin for fastening one end of said coupling member to said capping member, said string-attached cap being used with another end of said coupling member coupled to a vehicle,
- wherein said first electroconductive resins, said second electroconductive resin, and said third electroconductive resin are formed such that surface resistance from said capping member to said vehicle is set to be greater than or equal to 1×1012 Ω and less than 5.30×1012 Ω.
A string-attached cap comprising:
- a capping member formed of a first electroconductive resin;
- a ring member engaged in an outer periphery of said capping member;
- an elongated coupling member formed of a second electroconductive resin which is flexible;
- and
- a fastening member formed of a third electroconductive resin for fastening one end of said coupling member to said ring member, said ring member being formed of a fourth electroconductive resin, said string-attached cap being used with another end of said coupling member coupled to a vehicle,
- wherein said first electroconductive resins, said second electroconductive resin, said third electroconductive resin, and said fourth electroconductive resin are formed such that surface resistance from said capping member to said vehicle is set to be greater than or equal to 1×1012 Ω and less than 5.30×1012 Ω.
A string-attached cap comprising:
- a capping member formed of a first electroconductive resin and having an annular groove formed in its outer periphery;
- and
- an elongated coupling member formed of a second electroconductive resin and being flexible, said coupling member having a ring member formed integrally at one end thereof, an engaging part which is formed integrally with an inner periphery of said ring part being rotatably engaged in said annular groove of said capping member, said string-attached cap being used with another end of said coupling member coupled to a vehicle,
- wherein said first electroconductive resins and said second electroconductive resin are formed such that surface resistance from said capping member to said vehicle is set to be greater than or equal to 1×1012 Ω and less than 5.30×1012 Ω.
