昇降用ギヤ機構が収納されたギヤケースに開度計
のハウジングを取付け、 上記ギヤ機構と上記開度計の指針側との間に該
ギヤ機構の回転を減速して指針側に伝達する指針
駆動機構を介在させたゲート開閉装置において、 上記指針駆動機構におけるギヤケース側から開
度計側への回転伝動をチエーン伝動とし たことを特徴とするゲート開閉装置。[Scope of Claim for Utility Model Registration] A housing for a position gauge is attached to a gear case housing a gear mechanism for lifting and lowering a valve stem driven by a rotational operation of a handle, and between the gear mechanism and the pointer side of the position meter. In a gate opening/closing device in which a pointer drive mechanism is interposed which decelerates the rotation of the gear mechanism and transmits it to the pointer side, the rotation transmission from the gear case side to the opening gauge side in the pointer drive mechanism is a chain transmission. Characteristic gate opening/closing device.
