PROBLEM TO BE SOLVED: To provide a portable bit holder that allows mounting and dismounting operation of a bit to be easily performed with one hand, does not require troublesome maintenance and has excellent practicability.SOLUTION: In a mounted part 1 that can be mounted on a worker W are provided suspending parts 4 that suspend a bit 2 comprising constricted parts 3. In the suspending parts 4 are formed latching holes 6 that can latch the bit 2 to a plate material 5. The latching holes 6 are configured to be latched with the constricted parts 3 by setting the hole widths thereof smaller than the outer diameter of the bit 2 and larger than the outer diameters of the constricted parts 3, and formed into slit long holes 6 having vertical lengths. The bit 2 having the constricted parts 3 latched to the latching holes 6 is configured to be slidable in a vertical direction, and the plate material 5 is bent in a curved shape so that the latching holes 6 become long holes 6 in an arc chape. To an upper parts of the latching holes 6 are connected inlet/outlet hole parts 7, larger in diameter than the outer diameter of the bit 2, into/from which the bit 2 can be freely inserted/removed. |
