る（特公昭５９−１２５１５号参照）。Conventional technology In this way, in order to drive an auxiliary device such as a generator that requires constant speed rotation from the main engine, the PTO shaft on the auxiliary side must be rotated at a constant speed regardless of changes in the main engine speed. A constant speed rotation device is required to maintain the speed. Conventionally, as such a constant speed rotation device, a plurality of gear trains with different gear ratios are provided between the output shaft on the engine side and the constant speed PTO shaft, and the engine rotation is controlled so that the PTO shaft rotates at a substantially constant speed. There is a system in which one of the gear trains is selected in response to a change in the number of gears to transmit power (see Japanese Patent Publication No. 59-12515).

る。Problems to be Solved by the Invention However, in the conventional constant speed rotation device described above, the allowable rotation range in which the engine rotation speed changes is divided into multiple stages between the output shaft on the engine side and the constant speed PTO shaft. Therefore, it is necessary to provide a gear train with a different gear ratio for each division stage, and each gear train requires a clutch for power engagement and disengagement, which requires a large number of parts such as gears and clutches. This has the disadvantage that the entire device becomes larger and the cost becomes higher.

れる。As described in detail, in this invention, a continuously variable speed belt transmission mechanism is provided between the drive shaft and the constant speed PTO shaft, and the constant speed PTO shaft is determined based on the detection result of the rotation speed detection means. Since the continuously variable transmission type heald transmission mechanism is controlled to rotate at high speed, unlike conventional systems that use multiple gear trains, a single belt transmission mechanism is used between the drive shaft and the constant speed PTO shaft. The number of parts can be significantly reduced, resulting in a low cost and compact configuration.
