Abstract

A workpiece conveyance device is used for a press device. The workpiece conveyance device includes a support component, first and second moving members, a driver, and a transmission mechanism. The support component supports a holder that detachably holds a workpiece. The first moving member pivotably supports the support component. The first and second moving members are movable in the up and down direction. The driver moves the second moving member in the up and down direction. The transmission mechanism transmits an up and down movement of the second moving member to the first moving member so as to move the first moving member in the up and down direction in conjunction with the up and down movement of the second moving member. The transmission mechanism causes an amount of movement of the first moving member to be greater than an amount of movement of the second moving member.
