The Japanese 105 mm gun, Type 14, is a medium field weapon mounted on a two-wheeled carriage and drawn by a prime mover. The tube, of built-up construction, is retracted above the trails when in traveling position to provide proper balance. A breechblock of the interrupted screw type is used.
The weapon has split trails which may be adjusted to equalize cant. The wheels are equipped with rubber or steel tires.
The recoil system is the variable, hydropneumatic floating piston type. The fluid passage to the other side of the two air cylinders is suitably interrupted when the elevation is increased.
The traversing mechanism consists of a worm and arc gear. The elevating mechanism is of the arc gear type. A spring equilibrator is attached to the gun, since the trunnion is retracted in relation to the tube. The sighting equipment consists of a panoramic sight and a drum type range scale.
