PROBLEM TO BE SOLVED: To provide a hydraulic transmission mechanism in a running vehicle compactly attachable to a case of a gear type transmission. SOLUTION: The hydraulic transmission mechanism is provided with an actuator aggregation part 46 centrally arranged with hydraulic actuators 51, 52, 53, 54 of the hydraulic transmission mechanism automatically carrying out engagement and disengagement of a hydraulic clutch 26, and speed change of the gear type transmission by the hydraulic actuators 51, 52, 53, 54 on the basis of a speed change command to change a travel speed, and a solenoid valve aggregation part 47 centrally arranged with solenoid directional control valves 66, 67, 68, 69, 71, 72 controlling the hydraulic actuators 51, 52, 53, 54. The actuator aggregation part 46 and the solenoid valve aggregation part 47 are respectively arranged in a periphery of the case 3 of the gear type transmission apart from each other while hydraulically connecting them via a hydraulic circuit connecting object 48.
