PROBLEM TO BE SOLVED: To provide a door closer 1 for a storage box for constituting an elastic force adjustment mechanism P capable of varying a tension force thereof large-small, by adjusting an expansion degree of an elastic member (a tension coil spring 8) by an adjustment claw part 20 and a tooth-row part 9.SOLUTION: The elastic force adjustment mechanism P can adjust an expansion degree of the tension coil spring 8 large-small, by engaging a tip claw 20a of the adjustment claw part 20 with a desired tooth part 9a among a plurality of tooth parts 9a by sliding operation. Thus, resistance force when opening a door and a deceleration rate when closing, can be desirably adjusted with simple operation in response to opening-closing operation force of a user such as a powerless person and a robust person, needles to say to calmly execute opening-closing operation of a slide door 3. |
