PROBLEM TO BE SOLVED: To provide a brush for oral care in which there is no probability of falling off of a bristle even when a twist brush is curved for use of it.SOLUTION: A brush 1 for oral care comprises: a twist brush 2 comprising a loop part 4 and a root part 5; and a shaft member 3 for fixing the root part 5. The twist brush 2 comprises: a wire core 6 formed of a pair of twisted metal wires 6a, 6b; and an elastic filament 7 which is held so as to form a spiral row between the wires 6a, 6b along twisting. The filament 7 is formed of a spiral filament. One metal wire 6a is inserted into the spiral filament 7, and is twisted with the other wire 6b, thereby the spiral filament 7 is held in a spiral-state along the twisting. The loop part 4 is configured so that a part of the wire core 6 for holding the spiral filament 7 is bent into an annular shape. The root part 5 is configured so that, both end parts of the wire core 6 are twisted together so as to close the loop.SELECTED DRAWING: Figure 1 |
