Claims

[Scope of utility model registration request]

A pair of left and right transmission cases 4A, 4B each having a pair of left and right running wheels 2a, 2b attached so as to be freely drivable.
are provided in a line-symmetrical state, and each of the pair of transmission cases 4A, 4B is equipped with a traveling clutch gear (11a or 11b) that slides in and out of the direction along the axle axis X. 11a or 11b) operating shaft (14
a or 14b) in the direction along the axle center X, and the transmission case (4A or 4B)
A traveling transmission device which is disposed through the vehicle in a state of protruding into the inside of the aircraft body, the traveling transmission device being a traveling transmission device which is installed through the body in a state of protruding into the inside of the fuselage body, and includes a pair of said traveling clutch gears 1.
The gears (10a or 10b) to be engaged and disengaged of each of 1a and 11b are formed so that their mounting positions can be changed with respect to their supporting shafts (9a or 9b), and one of the operating shafts 14a is attached to the traveling clutch gear. 11a is arranged so that the direction in which it moves relative to the aircraft body for the engagement operation is the same as the direction in which the other operating shaft 14b moves relative to the aircraft body for the engagement operation of the traveling clutch gear 11b. The driving transmission device is fixed to the support shaft (9a or 9b), and the pair of operating shafts 14a, 14b are interlocked with one clutch operating lever 17.
