[Effect of the invention]

As described above, the carriage according to the present invention has the following effects. The front and rear needle selection for argyle knitting can be automatically performed according to the pattern by electronic control without manual operation. Since the left and right electromagnetic needles and the swing cam and the center guide cam, which are guide cams for them, are integrated in the center of the rear surface of the carriage, the size of the carriage can be reduced, and in particular, the length of the carriage can be reduced. A common swing cam is pivotally mounted between the left and right electromagnetic needle selection sections, and the knitting needle bat is moved by the single swing cam to the rear of the carriage in the carriage traveling direction when the carriage slides on either side. Since the guide is provided to the needle selector, the number of parts can be reduced. The center guide cam is located between the left and right electromagnetic selectors and in front of the swing cam to be common to the left and right electromagnetic selectors. Since the guide portion is formed and a part of the front guide passage of the carriage is formed on the front side surface, the number of guide cams can be reduced. It is sufficient to provide only one knitted fabric presser at the center of the knitted fabric presser unit. If the knitted fabric presser can be switched to a position deviated to one of the left and right sides from the center position of the knitted fabric presser unit,
It is possible to avoid a problem that the knitting fabric presser gets in the way and hinders the passing and unhooking of the knitting yarn to and from the yarn feeder.
