Abstract
An advancing-retracting member (3) which is tubular is hermetically inserted into a housing (1) so as to be movable in an vertical direction. An advancing-retracting mechanism (13) is provided to the housing (1) so as to move the advancing-retracting member (3) in the vertical direction. A support cylinder (17) is provided in a manner so as to protrude upward from the advancing-retracting member (3) and be insertable into a hole (21) formed in a workpiece (20). A pressing surface (4) formed in a top end portion of the advancing-retracting member (3) is able to push the workpiece (20) up. In a case where the advancing-retracting mechanism (13) moves the advancing-retracting member (3) upward, the advancing-retracting member (3) causes the support cylinder (17) to be inserted into the hole (21) of the workpiece (20) from below, and the advancing-retracting member (3) presses against the workpiece (20) via the pressing surface (4) so as to move the workpiece (20) upward.
