In the handle grip portion of the solenoid type firing handle having such a structure, the grip ring 2 pivotally attached to the grip body 1 is
When the operator stops the action of rotation, the return spring 46 acts to return to a predetermined position. In the present embodiment, the oil is attached to this shaft-attached portion as in the first embodiment. A damper 5 is attached. That is, the oil damper 5 is covered on the shaft rotatably attached to the grip ring 2 and the grip body 1, and the oil damper 5 is inserted between the grip ring 2 and the bearing in the grip body 1 through which the shaft is inserted. Intervening. As the oil damper 5, the same oil compound as that used in the first embodiment was interposed so as to cover the shaft. In addition,
The oil compound used in this embodiment is the same oil compound (product number: TSK5450) manufactured by Toshiba Silicone Co., Ltd. as used in the first embodiment.

By doing so, the dynamic torque can be increased while maintaining the static torque of the rotating shaft connecting the grip ring 2 and the grip body, and the rattling of the handle can be reduced. In addition, it prevents a slight movement of the handle due to hand shake and stabilizes the handle operation, and even when the handle operation is released and the handle returns to the original position, a recoil impact due to the return operation occurs in the stopper part. Things will disappear.

In the second embodiment, the damper means is rotatably attached to the grip ring 2 and the grip body 1 by covering the shaft with an oil damper 5 and the shaft is inserted. The oil damper 5 is interposed between the grip ring 2 and the bearing in the grip body 1. The damper is disposed between the grip ring 2 and the bearing in the grip body 1 through which the shaft of the grip body 1 is inserted.
