Is configured to be expandable and contractible only within the range of the long hole a. 13 is the telescopic arm
The rotating arm 9 is a first urging means for urging the other locking member 8 toward one locking member 7 side via the first biasing means 10.
It is provided inside the.

Reference numeral 14 denotes a second urging means for urging the work holding member 5 toward the side of the transport vehicle body 1. The second urging means is provided on the lower side of the support column 4 and the longitudinal intermediate portion of the rotating arm 9, respectively. 1
Although the coil springs 17 and 17 are provided and the coil springs 17 are stretched over the horizontal bars 15 and 16, the coil springs 17 may be replaced by gas springs.

Reference numerals 18 and 19 denote vehicle body lifting handles pivotally attached to the upper and lower sides on the other side of the column 4 of the transport vehicle body 1, and 20 is a pulling tool composed of a rope for raising the vehicle body. Both ends are fixed in the vicinity of, and the length thereof is set to be longer than the dimension between the fixing portions at both ends, and the slide cover 21 is provided. Reference numeral 22 denotes a shock absorbing rubber provided in the middle of the longitudinal direction of the support column 4, which has a function of buffering the impact contact of the work holding member 5 with the support column 4 by the urging means 14 as well as the support column 4 and the work supporting member 5. It also has a function of forming a space between and to facilitate gripping of the column 4 by an operator.

Next, with reference to FIG. 3 to FIG. 9, one mode in which the plate-like works 6 stacked in a predetermined stage and in a lying-down posture are raised and held on the carrier body 1 will be described. First, as shown in FIG. 3, the transport vehicle body 1 is positioned on the side of the stacked work 6 so that the locking members 7 and 8 of the work holding member 5 are directed toward the stacked work 6 side. Further, as shown in FIG. 4, the transport vehicle body 1 is placed on the work 6, and the other locking member 8 is attached to the upper portion 2.
It is locked to one edge of the plate-shaped workpiece 6.

Next, as shown in FIG. 5, the handle 19 on the lower side is grasped to pull the carrier body 1 together with the two works 6 toward the front, and as shown in FIG. The one locking member 7 is locked to the other edge portion of the. The locked state of the work 6 by the locking members 7 and 8 is held by the biasing force of the first biasing means 13.
