Abstract
The back face of a main blade body includes mounting parts, with a box structure having a mounting hole opened in the width direction and a cross section intersecting the width direction is non-circular. At the back face of each width expansion blade body is a fitting part, removably inserted into the mounting hole. A latching member latches the fitting part fitted in the mounting hole. For width expansion, the fitting part is fitted from the outer end side of the mounting hole to position the width expansion blade body at an end of the main blade body. For the housing, the fitting part is fitted from the inside of the mounting hole to house and position the width expansion blade body at the back face of the main blade body. In the width-expanded state, loads are received by the corresponding mounting part to lighten the burden placed on the latching member.
