(2) A request for registration of a utility model in which the elevating shaft is a worm-type spindle equipped with a worm-toothed screw, which is disposed orthogonally between a pair of driven shafts and is interlocked with each other by a worm wheel to move up and down. The gate operating device according to item 1.

(3) Utility model registration claim 1, wherein the clutch is a multi-disc clutch including frictional clutch plates, and is engaged with and disengaged from the drive shaft by opening and closing fingers.
The gate operating device according to item 1 or 2.

(4) The reversal prevention mechanism is a cam clutch,
The gate operating device according to any one of claims 1 to 3, which is provided in association with a hollow shaft provided on the drive shaft and is separable from the drive shaft. .

(5) The powder brake is a brake casing provided on a brake shaft that is filled with lubricating oil together with a fixed rotor and steel balls. Gate operating device according to one item.
