To reduce stress concentration caused by tensile force applied to a handle knob in a vehicle door handle mechanism.SOLUTION: A door handle mechanism, including a handle case 20 on a door panel 2 of a vehicle and a handle knob 30 pivotally attached thereto, in which: one of the handle case 20 and the handle knob 30 has a fitting convex portion 21 and the other has a fitting receiving portion 31; the fitting convex portion 21 has a high-convex region 24 and a low-convex region 25 lower than this region; the fitting convex portion 21 has a main interference range from a maximum opening handle acting portion 21b of the fitting convex portion 21 to a stopper acting portion 21a of the fitting convex portion 21 toward the opening side in the circumferential direction; the low-convex region 25 includes a lowest convex region 26 that protrudes lowest in the low-convex region 21 from the base end of the fitting convex portion 21 in the protruding direction of the fitting convex portion 21 and the lowest convex region 26 is arranged within a minimum height range of 180° from the center in the circumferential direction of the main interference range toward the opening side in the circumferential direction.SELECTED DRAWING: Figure 5
【課題】車両用ドアハンドル機構にて、ハンドルノブに加えられる引張力に起因する応力集中を低減する。【解決手段】本発明のドアハンドル機構は、車両のドアパネル２上のハンドルケース２０と、これに旋回可能に取り付けられるハンドルノブ３０とを有し、ハンドルケース２０及びハンドルノブ３０の一方が嵌合凸部２１を有し、同他方が嵌合受け部３１を有し、嵌合凸部２１が、高凸領域２４と、これよりも低い低凸領域２５とを有し、嵌合凸部２１は、嵌合凸部２１の最大開放取っ手作用部２１ｂから円周方向の開放側に向かって嵌合凸部２１のストッパ作用部２１ａに至る主干渉範囲を有し、低凸領域２５が、嵌合凸部２１の突出方向にて嵌合凸部２１の基端から、低凸領域２１中で最も低く突出する最低凸区域２６を含み、かつ最低凸区域２６は、主干渉範囲の円周方向の中央から円周方向の開放側に向かって１８０°の最低高さ範囲内に配置されている。【選択図】図５
