The present invention relates to an apparatus for preventing pin separation. According to the present invention, a buffer member is inserted between a pin and a bolt coupled with an entrance of a pin insertion hole into which the pin is inserted. Here, multiple wedge-shaped separation preventing bumps are formed on the outer circumference of the buffer member, and grooves corresponding to the separation preventing bumps are formed on the inner circumference of the pin insertion hole into which the buffer member is inserted. Therefore, the separation preventing bumps of the buffer member, which are inserted into the grooves of the pin insertion hole at the time of pin insertion, are caught by the grooves and thus are not separated after the pin insertion. Therefore, despite the long-term vibration, the buffer member is prevented from being pushed out to the entrance of the pin insertion hole, thereby preventing the transferring of the vibration to the bolt and thus fundamentally blocking the separation of the pin from a device. |
