Document Type and Number:
Japanese Patent JPS63110036
Kind Code:
A
Abstract:
PURPOSE:To change speed smoothly by eliminating any lack of hydraulic pressure through operation of a throttle arm gradually to the accelerating side when an operating lever is operated in the direction receding from a neutral position. CONSTITUTION:A hydraulic type speed changing device 1 being connected to an engine 3 to interlock with each other enables a running gear 7 to move forward or rearward and to accelerate or decelerate. An operating lever 2, guided in a operating guide groove 11, is constituted so that if it is operated to one direction, based on a neutral position A, the forward speed will gradually increase and if it is operated to the opposite direction, based on the neutral position A, the rearward speed will gradually increase.
