Abstract
A manual breaker for cutting sheet glass. The manual breaker includes a rotational shaft (6) that rotatably holds first and second arms (2) and (4). A sheet glass having a scribe line formed thereon in advance is pinched among rollers (24) and (45). When handles (20) and (40) are actuated to narrow a distance between rollers (24) and (45), the roller (45) moves in a Y-axis direction and an impact shaft (51) impacts the sheet glass, accordingly. The sheet glass can be thereby easily cut into pieces along the scribe line and a sectional quality having a smooth cut surface can be ensured for the sheet glass.
