Portable wireless key
In a portable wireless key, decoration fitting portions provided at ends of a pair of side portions of a metal decoration member are fitted in decoration receiving portions of a wireless key body, and a decoration engaging portion provided at a connecting portion of the metal decoration member is engaged with a decoration engagement portion of the wireless key body. Further, a switch operation cover is fixed to an assembled unit of the wireless key body and the metal decoration member. Thus, durability in dropping can be improved without complicating an assembling work of the metal decoration member and without increasing the number of components and costs, and it is easy to address switch variations without increasing initial costs.
