To provide a brake structure which can safely and reliably brake a wheel even if an emergency such that advance/retreat operation cannot be input to an operation input unit 21 occurs.SOLUTION: A brake structure comprises: an operation input part 21 which is provided in the front of a driving seat 14 of a vehicle and to which advance/retreat operation is input by normal brake operation; and a brake body part 22 which brakes a wheel 15 by advance/retreat operation of the operation input part 21. Further, the brake structure comprises: an emergency drive source 26 which retains driving force during normal operation and releases the same during emergency; and an emergency operation part 27 which operates advance/retreat of the operation input part 21 by the driving force from the emergency drive source 26.SELECTED DRAWING: Figure 1
【課題】操作入力部21に進退動作を入力できなくなるような緊急事態が生じても、安全で確実に車輪を制動させ得るブレーキ構造を提供する。【解決手段】車両の運転席14の前方に配設されて通常時のブレーキ操作により進退動作が入力される操作入力部21と、操作入力部21の進退動作により車輪15を制動するブレーキ本体部22と、を備えたブレーキ構造において、通常時に駆動力を保持して緊急時に放出する緊急時駆動源26と、緊急時駆動源26からの駆動力により操作入力部21を進退動作させる緊急時作動部27と、を備えている。【選択図】図1
