扭矩检测装置和电动助力转向装置
摘要：
本发明提供能够抑制静电侵入集磁支架的内侧的扭矩检测装置和具备该扭矩检测装置的电动助力转向装置。集磁单元具备：集磁环；第一集磁支架和第二集磁支架，它们对集磁环分别进行保持；以及磁屏蔽罩，其覆盖集磁环的外周。在第一集磁支架的内周面设置有凹部。在第二集磁支架的外周面设置有向凹部插入的卡合突起。在第二集磁支架的内周面设置有凹部。在第一集磁支架的内周面设置有朝向第二集磁支架突出的突起。在组装了第一集磁支架和第二集磁支架时，突起插入凹部。
摘要（英）：

A torque detection device capable of suppressing intrusion of static electricity thereinto. A magnetism collection unit includes magnetism collection rings, first and second magnetism collection holders that hold the magnetism collection rings, respectively, and a magnetic shield that covers the outer peripheries of the magnetism collection rings. The inner peripheral surface of the first magnetism collection holder is provided wife recessed portions. The outer peripheral surface of the second magnetism collection holder is provided with engagement protrusions to be inserted into the recessedportions. The inner peripheral surface of the second magnetism collection holder is provided with recessed portions. The inner peripheral surface of the first magnetism collection holder is provided with protrusions that project toward the second magnetism collection holder. The protrusions are inserted into the recessed portions when the first magnetism collection holder and the second magnetismcollection holder are assembled to each other.
