Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely execute normal operation and release restoration operation, by eliminating a factor of hindering driving of a gate, regardless of weather such as snowfall time and an environment such as a severe cold district.SOLUTION: In a gate device 1, a rotary driving part 22 determines a start phase of rotary operation of a rotary part 13 so that a gate bar 16 existing in a side-lying position intercepts a vehicle passage 2 when regulating passing of a vehicle, and determines an end phase of the rotary operation of the rotary part 13 so as to hold the gate bar 16 by a gate bar base part 15 by rotating the rotary part 13 so as to follow up the rotary operation of the gate bar 16 when the gate bar 16 executes release operation for rotating in the movement direction of the vehicle around a release rotary shaft 51 when the gate bar 16 separates from the gate bar base part 15. The rotary driving part 22 is also constituted so as to increase rotary operation force for rotatingly operating the rotary part 13 as the rotary part 13 becomes near to at least the start phase.SELECTED DRAWING: Figure 5
