Both ends of the main shaft of the engine, which is disposed between the two support members 28, are brought into contact with the support member 28 at the tip of the clamping arm 24, and are clamped from both left and right sides.

Next, unnecessary parts of the fixed engine, such as parts such as a carburetor made of zinc, a fuel pump, and a starting motor containing copper, and a muffler that takes up a large amount of space, are grabbed by the dismantling tool 30B, and then the arm 10.
The part is torn by operating 12. At this time, if the parts to be removed by the disassembly tool 30B are attached to the lower back side of the engine, the engine is rotated by the tip of the disassembly tool 30B with the gap between the clamping arms 24 slightly widened. and then resume work after it is in a good position.

At this time, even when the interval between the clamping arms 24 is widened, the engine is supported within the support member 28 without falling because the support member 28 has a curved concave shape.

Next, after removing unnecessary parts, the clamping arm 24
The engine is opened to the left and right, and the engine is grasped by the disassembly tool 30B and moved to a predetermined location.

The disassembled engine is then placed in a melting furnace and melted at a temperature close to the melting point of aluminum (660'''C) to extract aluminum, which is then poured into a mold to form an ingot.

[Problems to be Solved by the Invention] The demolition work tool 30B used in the above-mentioned demolition apparatus has a plurality of recesses arranged from the tip to the base of the blade surfaces of the opposing double-edged portions 32B and 34B. This point is suitable for gripping parts.

However, when it is necessary to insert one of the blade sections 32B, 34B into a narrow gap in order to remove a component, the plurality of recesses become an obstacle and the insertion cannot be performed. For example, consider a case where a starter motor is torn off from an engine supported by the clamping arm 24 using the dismantling work tool 30B. in this case,
First, with the blade parts 32B and 34B spread out, one of the blade parts (for example, the blade part 34B) is inserted between the engine and the starter motor. Next, the starter motor is removed by scratching with the blade part 34B, or the double-edged parts 32B and 34B are closed, and the starter motor is peeled off from the engine by moving the disassembly tool 30B. However, as mentioned above, there is a problem in that the recessed portion becomes an obstacle and the blade portion 34B (or blade portion 32B) cannot be inserted between the engine and the starter motor.
