To prevent loosening of a set screw that is screwed in through the tube wall from the lateral direction of a curved tube against an inner member that is placed inside near the curved portion of the tube.SOLUTION: In a curved tube that constitutes a mounting portion 2b of a door handle to a door, a portion to which a plug 5 (inner member), which is arranged inside near a curved portion, is fixed is formed into an elliptical cross section where the dimension la in the horizontal direction is smaller than the dimension Lb in the vertical direction, so that the gap dimension in the horizontal direction between the mounting portion 2b and the plug 5 (δa1+δa2 ) is smaller than the longitudinal gap dimension (δb1+δb2). This allows a larger allowance for a set screw 6, which is screwed into the plug 5 through the tube wall from the lateral direction of the mounting portion 2b, than in the conventional design, effectively preventing the set screw 6 from loosening.SELECTED DRAWING: Figure 4
【課題】曲管の湾曲部の近傍の内側に配される内方部材に対して、曲管の横方向から管壁を通してねじ込まれる止めネジの緩みを防止する。【解決手段】ドアハンドルのドアへの取付部２ｂを構成する曲管において、その湾曲部の近傍の内側に配されるプラグ５（内方部材）が固定される部位を、横方向の寸法Ｌａが縦方向の寸法Ｌｂよりも小さい楕円形断面に形成して、その取付部２ｂとプラグ５の横方向の隙間寸法（δａ１＋δａ２）が縦方向の隙間寸法（δｂ１＋δｂ２）よりも小さくなるようにした。これにより、取付部２ｂの横方向から管壁を通してプラグ５にねじ込まれる止めネジ６のかかり代が従来のものよりも大きくなり、止めネジ６の緩みを効果的に防止することができる。【選択図】図４
