Claims

[Scope of utility model registration request]

The actuating lever is connected to one end of the actuating rod via a ball joint, and these connecting parts are covered with an elastic boot such as rubber to insulate the ball joint connecting part located close to a heat source such as an engine. The heat insulator is composed of a bowl-shaped cap part that covers the outer periphery of the elastic boot, and a semi-cylindrical cap part that is integrally provided with the cap part and covers the outer periphery of one end of the actuating rod. , a first engaging means that engages with an engaging portion provided on the outer periphery of the actuating rod in the semi-cylindrical cap portion to restrict axial movement with respect to the actuating rod; and a first engaging means that restricts rotation in the circumferential direction. A heat insulator for a ball joint connection portion, comprising a second securing means.
