We have studied transport properties in the low-temperature magnetoresistance through the ballistic narrow path restricted by a short width metallic gate on the 2 dimentional electron gas (2DEG) system. An alternate and systematic variation between a Lorentzian line fitting and a cusp-like line fitting in the zero-field peaks has been observed, as sweeping the gate voltage. It indicates a possibility of existence of chaotic and regular paths on the short gated ballistic/tunneling transport. We will discuss on the quantum chaos behavior on the systematic variation between the Lorentzian and the cusp-like peakshape based on the disordered path system under the short gate.
