Structure for mounting brush holders on electrically powered tool e.g. electric screwdriver, has elastic strip that presses against positioning hole inner walls so brush holder is removably held at defined position

摘要

The structure has at least one positioning hole (16) with inner walls formed at a predefined position in a housing (10) at which the brush holder (2) is to be mounted and at least one elastic strip (7) that protrudes from the holder for insertion into the hole when the holder is mounted at the predefined position. The elastic strip presses against at least one of the inner walls of the hole when inserted into the hole so that the brush holder is removably mounted at the defined position.
