プリング（３）は略密着して小さくなる。(Function) Rotational power is generated by fixed pulley piece (1) and moving pulley piece (2)
It is transmitted by a transmission pulley formed of When an abnormality occurs in the fuselage and the transmission pulley generates heat, this heat is conducted to the spring (3), so the spring (3), which has shape memory properties, is brought into close contact with the spring (3) and becomes smaller.
従って、移動プーリ（２）はフリーになるので、べｌシ
ト０１）の回転も停止する。Therefore, since the movable pulley (2) becomes free, the rotation of the belt 01) also stops.

の回転動力を伝動するベルトである。First, to explain its configuration, the transmission pulley (4)
The fixed pulley piece (1) and the movable pulley piece (2) are made by press-working an iron plate to form a dish shape, and their backs are in close contact with each other.
). The fixed pulley piece (1) is
The movable pulley piece (2) is fixed to the outer circumferential surface of a boss (7) that is inserted through a key (6) to a rotating shaft (5) that is rotatably provided. It is movable in the axial direction (in the direction of the arrow). Then, on the surface of the movable pulley (2) opposite to the fixed pulley piece (1),
One end side is received by the receiving plate (8), and the movable pulley piece (2
) to the fixed pulley piece (1).
) has been established. The spring (3) is made of a shape memory alloy, and is open when the temperature is below a predetermined temperature, and becomes in a substantially close contact state when the temperature is above a predetermined temperature. Further, although the spring (3) is made of a shape memory alloy, it is not limited to an alloy, and any material having shape memory properties and similar functions may be used. (9) is a fixing nut that fixes the boss (7). θQ is a switch that turns ON when the movable pulley (2) moves by a predetermined amount or more, and although not shown, this switch αO becomes l'-C)NJ.
The system is configured to activate a notification means (buzzer, lamp, voice, etc.) to notify the user when this occurs. αυ is transmission pulley (4)
A belt that transmits rotational power.

At this time, the movable pulley (2) pressed by the spring (3) also rotates together with the fixed pulley (1) due to friction with the fixed pulley (1), so the rotational power is further transferred to the bell l-(11 )

When the temperature reaches a predetermined level or higher, the spring (3) that has received this heat becomes in a state of close contact and becomes smaller, so the movable boo 'J (2) u
You can move freely in the direction of the arrow on the boss (7). Therefore, rotation of the belt αD by the transmission pulley (4) is stopped, and burnout can be prevented. In addition, the moving pulley (2
) moves in the direction of arrow (A) by a predetermined amount or more, this moving pulley (2) turns on the switch (11) to notify the operator of the abnormality. Therefore, the operator only has to immediately disconnect the drive source such as the prime mover or motor or the transmission clutch.
