Abstract

In a retainer member for retaining a noise reduction member, a retaining portion for retention of a noise reduction member wound with a cable is provided with a claw for locking the cable wound on the noise reduction member.

First claim

The invention claimed is:

1. An electrical noise reduction apparatus comprising:
an electrical noise reduction member and a conductor cable wound on the noise reduction member, the electrical noise reduction member suppressing electrical noise propagating through the conductor cable, and
a retaining member including a retaining portion for retention of the electrical noise reduction member,
wherein the retaining portion includes a claw and the claw is inserted between the electrical noise reduction member and the conductor cable wound on the electrical noise reduction member so that the electrical noise reduction member is retained by the retaining member, and
wherein the conductor cable is locked in position by the claw inserted between the electrical noise reduction member and the conductor cable wound on the electrical noise reduction member.

2. The electrical noise reduction apparatus according to claim 1 , wherein
the retaining portion includes a suspension portion for suspending one end of the conductor cable wound on the electrical noise reduction member and extended from the electrical noise reduction member.

3. The electrical noise reduction apparatus according to claim 1 , wherein
the retaining portion includes a placement portion for placement of the electrical noise reduction member relative to the retaining portion.

4. The electrical noise reduction apparatus according to claim 1 , wherein
more than one of the retaining portions is provided.

5. The electrical noise reduction apparatus according to claim 1 , further comprising a cover part for covering a proper area.

6. The electrical noise reduction apparatus according to claim 1 , further comprising a fixing portion for fixing the retainer member to a mount subject.

7. A retaining device in combination with an electrical noise reduction member wound with a conductor cable, the electrical noise reduction member suppressing electrical noise propagating through the conductor cable, the retaining device comprising:
a retaining member including a retaining portion for retaining the electrical noise reduction member, the retaining portion including a claw,
wherein the electrical noise reduction member is fixed on the retaining device by the claw, which is sandwiched between the conductor cable and the electrical noise reduction member so that the claw is inserted between the electrical noise reduction member and the conductor cable wound on the electrical noise reduction member,
wherein the conductor cable is locked in position by the claw inserted between the electrical noise reduction member and the conductor cable wound on the electrical noise reduction member.

8. A method of retaining an electrical noise reduction member by a retaining device comprising the steps of:
providing an electrical noise reduction apparatus including the electrical noise reduction member and the retaining member including a retaining portion for retention of the electrical noise reduction member,
winding a conductor cable on the electrical noise reduction member, the electrical noise reduction member suppressing electrical noise propagating through the conductor cable; and
sandwiching a claw of the retaining device between the conductor cable and the electrical noise reduction member so that the claw is inserted between the electrical noise reduction member and the conductor cable wound on the electrical noise reduction member, and the claw retains the electrical noise reduction member on the retaining device,
wherein the conductor cable is locked in position by the claw inserted between the electrical noise reduction member and the conductor cable wound on the electrical noise reduction member.

9. The electrical noise reduction apparatus according to claim 1 , wherein the retaining member is a first retaining member, the claw is a first claw, and the electrical noise reduction member is a first electrical noise reduction member, the first retaining member further includes a suspension portion on which one end of the conductor cable wound on the first electrical noise reduction member is suspended, and
the apparatus further comprises a second electrical noise reduction member with a conductor cable wound thereon, a second retaining member with a second claw, the second retaining member further including a placement portion, wherein the second claw is inserted between the conductor cable and the second electrical noise reduction members rests on the placement portion.
