(EN) Provided are a lock bar and a lock bar drainage method capable of suppressing obstacles to walking and running on a ridge and capable of draining water reliably and smoothly. It can be embedded so as not to project from the ridge 1, and is joined to the protection tube 101 having the plug seat 113 provided therein, the core portion 102 extending inside the protection tube 101, and the lower end of the core portion 102. It is expandable and contractable along the extending direction of the plug part 104 and the core part 102, one end is joined to the plug part 104, and the other end is fixed to a desired position of the core part 102 so that the water level can be adjusted. The water level adjusting unit 105 including the flexible bellows unit 103 and the inside of the core unit 102 are disposed inside the protection pipe 101 to suspend the water level adjusting unit 105 so that the plug unit 104 is removed from the plug seat 113. The lock bar 10 includes a holding tube 106 that can hold the water.
