PROBLEM TO BE SOLVED: To provide a vehicular steering device which can obtain predictability of a failure while protecting a clutch device.SOLUTION: A vehicular steering device comprising a turning part 5 for turning a steering wheel 3 of a vehicle 1, and a steering part 7 having a steering reaction force actuator 13 which gives a reaction force for steering of a steering handle 9 by a user. The vehicular steering device comprises a clutch device 11, which performs an operation for making a mechanical connection state or an isolation state, between the steering part 7 and the turning part 5. Further, a mechanical fuse 15, which is torsionally deformed by input of an excessive load thereby so making that the load is not transmitted to the clutch device 11, is provided between the steering reaction force actuator 13 and the clutch device 11. On a lateral face part 15a of the mechanical fuse 15, a scribe line 16 is drawn.SELECTED DRAWING: Figure 1

    【課題】クラッチ装置を保護しつつ、故障の予見性を得られる車両用操舵装置を提供する。【解決手段】車両1の操舵車輪3を転舵するための転舵部5と、ユーザによる操向ハンドル9の操舵に対して反力を付与する操舵反力アクチュエータ13を有する操舵部7とを備える車両用操舵装置である。この操舵部7および転舵部5の間には機械的に連結状態とし、または切離状態とする動作を行うクラッチ装置11を備える。また、操舵反力アクチュエータ13とクラッチ装置11との間には、過度の荷重の入力により捻じれ変形して、荷重がクラッチ装置11に伝達されないようにするメカニカルヒューズ15が設けられている。このメカニカルヒューズ15には、側面部15aにけがき線16が描かれている。【選択図】図1
