求項３）記載の駐車ブレーキ。[Claims for Utility Model Registration] 1. In a parking brake that operates the parking brake by pulling the parking cable 4, the spring 1 applies pulling tension to the parking cable 4 to self-maintain the parking braking force. A parking brake for an industrial vehicle, characterized in that the self-holding of the parking braking force is released by compressing the spring 1 via a link 8 by a hydraulic actuator 10. 2. The hydraulic actuator 10 is controlled by a solenoid valve 12, and the solenoid valve operating solenoid 12a is energized only when both the manual switch 14 and the seat switch 15 are turned on, and the hydraulic actuator 10 is connected to the pressure oil supply pipe. The parking brake according to claim 1, characterized in that the parking brake communicates with the road 11a. 3. The pressure oil supply pipe 11a is connected to the upstream side of the flow divider 11, which is a hydraulic diversion circuit for dividing the pressure oil from the hydraulic pump P driven by the engine E for cargo handling and steering. The parking brake according to claim 2). 4 The pressure oil supply pipe 11a includes the pressure oil supply pipe 1
4. The parking brake according to claim 3, further comprising a shunt valve 13 which is closed when the pressure at the pressure 1a reaches a specified value.
