The rod pin 20 is installed in the hollow portion of the rod body 10 in a state in which the tip end is exposed, and the rear end portion of the rod pin 20 has an elastic member 30 for supporting it.

The elastic member 30 is formed of, for example, a coil spring, and is compressed to push the rod pin 20 by transmitting an elastic restoring force to the rear end of the rod pin 20.

The rod pin 20 has a locking projection 21 protruding from the rod pin 20 to prevent the rod pin 20 from being separated from the rod body 10 when the rod pin 20 is pushed by the elastic member 30.

The locking jaw 21 extends from the lead portion of the rod pin 20, that is, the outer peripheral surface of the tip portion, and protrudes from the top of the inclined end 23.

With the above configuration, the tip end portion of the rod pin 20 is usually used (before the elastic member 30 is compressed or deformed or the cam 40 is rotated to generate interference with the rod pin 20). It is formed in an exposed state.

In addition, the hood stay rod of the present invention is composed of a cam 40 rotatably assembled to the outer peripheral surface of the rod body 10, the outer peripheral surface of the rod pin 20 when the cam 40 to rotate the cam ( The inclined end 23 which interferes with the large end of 40 is formed.

The inclined end 23 is formed to protrude tapered from the rear of the locking jaw 21 toward the locking jaw 21 (or to the opposite side of the elastic member 30).

Therefore, when the user presses and rotates the cam 40, the large end of the cam 40 and the inclined end 23 interfere with each other, and the rod pin 20 interlocks and pushes toward the elastic member 30 due to contact slippage. The withdrawn tip of 20 will enter the rod body 10.
