Claims

[Scope of Claim for Utility Model Registration] 1. A set of two expandable members installed in the door car case are pivoted concentrically near one end of each other so as to be expandable to the left and right. A claw portion protruding outward is formed on the expansion side end opposite to the expansion member, and a pushing convex portion is formed on the inner side of both expansion members. A pawl portion of the expansion member is provided so as to be able to protrude from the hole, and a claw portion of the expansion member is provided in the center of both expansion members so as to be in contact with the pushing convex portion and extend from the expansion side end side toward the shaft support side end side. A movable pushing member is provided,
An inclined groove is formed on the left and right side walls of the pushing member, and an expansion adjustment screw rotatably attached to the door roller case is screwed into the sliding block that is slidably inserted along the left and right inclined grooves. The mounting structure of the door roller is characterized by: 2. The mounting structure for a door roller according to claim 1, wherein the expanding members are provided at two locations, front and rear of the wheel, in the door roller case.
