VEHICULAR SIDE MIRROR

To provide a vehicular side mirror which prevents co-rotation of a mirror base by fastening generated when the mirror base is attached to a mirror head to improve attachment accuracy.SOLUTION: A mirror base 3 has an attachment plate part 33 to which a base part 5a of a mirror head 2 is fastened. The attachment plate part 33 is formed with a harness insertion hole 33a and fastening holes 33b into which screws 100 for fastening to the base 5a are inserted. A jig X for preventing co-rotation of the mirror base 3 when the screw 100 is screwed from the fastening hole 33b to the base part 5a may be inserted into the insertion hole 33a. The insertion hole 33a has a rotation restriction part 33e which fits in a portion of the jig X which is inserted into the insertion hole 33a.SELECTED DRAWING: Figure 3 【課題】ミラーベースをミラーヘッドへ取り付ける際の締結によるミラーベースの連れ回りを防止し、取付精度を向上させる。【解決手段】ミラーベース３は、ミラーヘッド２の基部５ａが締結される取付板部３３を有し、取付板部３３には、ハーネス挿通孔３３ａ、及び、基部５ａと締結させるためのネジ１００が挿入される締結孔３３ｂが形成され、挿通孔３３ａは、締結孔３３ｂから基部５ａへネジ１００を螺合させる際に、ミラーベース３の連れ回りを防ぐための治具Ｘを挿通可能であり、挿通孔３３ａは治具Ｘの挿通孔３３ａに挿通されている部分と嵌合する回転規制部３３ｅを有する。【選択図】図３
