る。A gate of this type is disclosed in Japanese Patent Application Laid-Open No. 7-279564.
A pillar, an arm member rotatably supported by the pillar at one end, a door attached to the other end of the arm member, and an elastic force in the direction of flipping up the door against the own weight of the door and the arm member. It is known that the elastic member is provided with an elastic force applying means including a coil spring and a gas spring for applying the force to the arm member.

扉に、更に、電動モータを付加して、この電動モータに
より自動的にアームを回動させて扉の自動開閉を行わせ
るようにする場合、停電等で電動モータへの給電が行え
なくなっても扉を手動で開閉できることが好ましい。In addition to the flip-up type gate described in the above publication, an electric motor is further added, and the arm is automatically rotated by the electric motor to automatically open and close the door. It is preferable that the door can be opened and closed manually even when power cannot be supplied to the electric motor due to a power failure or the like.

当接が急激になされて大きな音を発生させる虞がある。Further, in the case of an automatic flip-up type gate, the operation of the electric motor is stopped after the door or the arm is brought into contact with the ground or a stopper in order to surely obtain the completely closed door and the completely opened door. , The electric motor seems to have been operated under high load condition from the contact to the operation stop,
In addition to making the operator feel uneasy and shortening the life of the electric motor, an unreasonable force is applied to the rotation transmission mechanism that transmits the rotation of the output rotation shaft of the electric motor to the arm. In addition to shortening the service life, inertia of the arm or the like due to the weight of the arm may abruptly make contact with the ground or a stopper or the like to generate a loud noise.

きないのである。Further, in this kind of flip-up gate, a gas spring is often used as a balancer for canceling the weight of the arm and reducing the load on the electric motor. The elastic force of the gas spring fluctuates considerably depending on the temperature. As a result, the door opening and closing speeds will be different due to load fluctuations of the electric motor between high temperature and low temperature, and the operator will feel uneasy. In particular, since the flip-up gate is usually placed outdoors where the temperature changes drastically, the characteristic variation of the gas spring due to this temperature change cannot be ignored.
