Abstract

A cleaning tool includes: a tool body; and an extension part extending from the tool body and including a head configured to press a cleaning body against a cleaning target. The head includes a conductor part made of a conductor.

Claims (36)

1 . A cleaning tool comprising:

a tool body; and

an extension part extending from the tool body and comprising a head configured to press a cleaning body against a cleaning target, wherein

the head comprises a conductor part made of a conductor, and

the conductor part is configured to move with respect to a pressing surface of the head between:

a first position where a front end face of the conductor part is behind the pressing surface, and

a second position where the conductor part is exposed on the pressing surface of the head and presses the cleaning body against the cleaning target.

2 . The cleaning tool according to claim 1 , wherein

the cleaning body is wrapped over a region of the pressing surface when viewed in a direction in which the head presses the cleaning body against the cleaning target, and

the conductor part is disposed in the region.

3 . The cleaning tool according to claim 1 , wherein

the head further comprises:

a supply opening from which the cleaning body is supplied to the pressing surface; and

a retrieve opening to which the cleaning body is retrieved from the pressing surface, and

the conductor part is disposed between the supply opening and the retrieve opening.

4 . The cleaning tool according to claim 1 , wherein

the cleaning body is in a string shape, and

the head further comprises a head body made of a resin.

5 . The cleaning tool according to claim 1 , wherein

the cleaning body is in a tape shape, and

the head is made of the conductor.

6 . The cleaning tool according to claim 1 , wherein

the tool body comprises a ground terminal, and

the conductor part of the head is capable of being grounded via the ground terminal.

7 . The cleaning tool according to claim 1 , further comprising:

a feeder that supplies the cleaning body to the head in a state where the head presses the cleaning body against the cleaning target.

8 . The cleaning tool according to claim 1 , wherein

in the second position, the front end face of the conductor part is aligned in a front-rear direction of the cleaning tool with the pressing surface of the head, and

the conductor part is configured to be in the first position when the extension part is not pushed into the tool body.

9 . The cleaning tool according to claim 1 , wherein

the tool body comprises an operation part configured to be operated by an operator, and

the conductor part of the head is electrically coupled to at least a portion of the operation part.

10 . The cleaning tool according to claim 9 , further comprising:

a front housing; and

a body housing in which the operation part is disposed, wherein

the front housing and at least a portion of the body housing are conductive to be electrically coupled to the conductor part.
