Abstract

PURPOSE:To surely stop a transfer member by forming a cylindrical body onto a gate member and projection part which projects to one side from said cylindrical body and is formed intermittently in the longitudinal direction of the cylindrical body and turning the gate member around the axis center of the cylindrical body. CONSTITUTION:After a transfer member 5 is shifted, together with a mast, along a mast rail 2, a gate member 6 is set into the state shown by the supported line. In this state, the projection part 58 of the transfer member 5 is fitted into the recessed part 63 formed between the projection parts 62 of the gate member 6, and the shift of said transfer member 5 is suppressed by the projection member 62. The turning operation of the gate member 6 is carried out by applying a torque onto one edge part of the gate member 6. In the gate member 6, a cylindrical body 61 is formed over the whole length, and since the torsional rigidity is large, th torque can be transmitted to the other edge without generating a torsional deformation, and the engaging operation of the transfer member 5 can be carried out surely.
