Abstract: Provided is a work vehicle capable of expanding a field of vision from inside a cab equipped with an operator protective guard. A front guard provided on a front side of a cab has a frame constituting an outer edge of the front guard. The frame is formed by framing an upper frame, a lower frame, a right vertical frame, and a left vertical frame. The right vertical frame has a vertical frame bent portion, and extends rearward toward the cab as it comes close to the lower frame from the vertical frame bent portion.

Abstract: A hydraulic excavator is a work vehicle equipped with a work implement, including a cab and a rotating light. The rotating light is removably disposed on a roof of the cab. The rotating light has a rotating light main body, an attachment component, and a handle. The attachment component is provided on the lower side of the rotating light main body and is used to attach the rotating light main body to the roof. The handle is portal-shaped and fixed to the attachment component, and has a first rod-shaped part, a second rod-shaped part, and a third rod-shaped part. The first rod-shaped part and the second rod-shaped part are formed facing upward from the attachment component. The third rod-shaped part connects the first rod-shaped part and the second rod-shaped part together. The third rod-shaped part is disposed above the rotating light main body when viewed from the side and perpendicular to the lengthwise direction.

Abstract: Provided is a guard-equipped cab for a work vehicle in which contact between a work implement and a member for coupling an operator protective guard to a cab can be avoided. A front guard is coupled by hinges to be openable/closable with respect to a cab for a work vehicle. A hinge has a shaft portion, a first plate member, and a second plate member. The first plate member is fixed with respect to a right front pillar. The second plate member is fixed with respect to the front guard. The first plate member has a support portion supporting the shaft portion, and extends from the support portion toward a left surface of the cab for the work vehicle.
