Abstract

Disclosed is an opening angle regulating device of a side door for a heavy equipment, which is provided between a door frame and the side door to regulate an opening angle of the side door. The opening angle regulating device includes a rod whose one end is rotatably fixed onto the door frame, and a bracket fixed onto the side door, having a guide rail slidably fixed to the other end of the rod depending on opening and closure of the side door, the guide rail having a groove that fixes the other end of the rod if the side door is opened at a predetermined angle. Preferably, the opening angle of the side door is regulated as the position of the groove is adjusted on the guide rail.

Claims

1. An opening angle regulating device of a side door for a heavy equipment, which is provided between a door frame and the side door to regulate an opening angle of the side door, comprising:

a rod whose one end is rotatably fixed onto the door frame; and
