<p>A lifting mechanism for a traverse mechanism, having a lifting pin (41), a lifting cam as a lifting means, and a lifting pin guide (43), and moving the traverse mechanism to a standby position, a clamp position, and a rotation position. A guide groove (44) is formed in the lifting pin guide (43) and guides the movement of the lifting pin (41) in the lifting direction of the traverse mechanism. The guide groove (44) has an orthogonal width H1 and an orthogonal width H2 greater than H1, where the width H2 is in the direction orthogonal to the lifting direction in a rotation position region R in which the lifting pin (41) is positioned when the traverse mechanism is in the rotation position, and the width H1 is the width of that region of the guide groove which is other than the rotation position region R. The width H2 is greater than a distance where the lifting pin (41) is movable in the direction orthogonal to the lifting direction of the lifting pin (41).</p> |
