PROBLEM TO BE SOLVED: To solve the problems of deteriorating an appearance due to exposing an irregular tooth, an elastic claw and an elastic claw-storage large groove to an external part after being installed in a mullion, and occasionally expanding a clearance between a sliding door and the mullion due to moving a shielding material when external force and vibration are added to the mullion, in a conventional cam type clearance adjusting device.SOLUTION: In a cam type clearance adjusting device of the present invention, the irregular tooth is formed on the end part outer periphery of a rotary body, and the elastic claw is erected in the axial direction in an inside end part of an outer cylinder. The rotary body is fitted to the outer cylinder, and the irregular tooth and the elastic claw are engaged, so that the irregular tooth and the elastic claw are not exposed to the external part, and since engagement between the irregular tooth and the elastic claw is stabilized, the clearance is not expanded over a long period. 【課題】従来のカム式隙間調整装置は、中方立に取り付け後、凹凸歯や弾性爪、該弾性爪収納用の大きな溝が外部に露出して外観を悪くしたり、中方立に外力や振動が加わると、遮蔽材が移動して引戸と中方立間の隙間を広くしたりすることがあった。【解決手段】本発明のカム式隙間調整装置は、回動体の端部外周に凹凸歯を形成し、外筒の内側端部に弾性爪を軸方向に立設してある。回動体を外筒に嵌合するとともに凹凸歯と弾性爪を係合することにより、凹凸歯や弾性爪が外部に露出せず、また凹凸歯と弾性爪の係合が安定するため、長期間に渡って隙間が広くなるようなことがない。【選択図】図１
