Electric noise absorber

A noise absorber for absorbing electric noise on a cable comprising:

• a body of magnetic substance formed such that it can surround the cable;
• and
• first and second case members for holding the body around the cable, where the case members are rotatably attached to each other so that the case members may rotate from an open position to a closed position in which the two case members form a case around the body, the first and second case members having
• two holding members inside each of the first and second case members, where each holding member in the first case member abuts one of the holding members in the second case member and the cable passes through and is held by two holes, one hole being defined by each pair of abutting holding members when the case members are in the closed position, and
• two wall members on each of the first and second case members, where each wall member on the first case member abuts a wall member on the second case member, the cable passes through two openings, one opening being defined by each pair of abutting wall members when the case members are in the closed position, and the openings have greater diameters than the holes;
• where
• the body, the two pairs of abutting holding members, and the two pairs of abutting wall members are spaced along the axis of the cable such that the body is located between the two pairs of abutting holding members and each pair of abutting wall members is located outside the two pairs of abutting holding members, one pair of abutting wall members on either side of the body.
