<P>PROBLEM TO BE SOLVED: To prevent a battery holder from causing a rattle with respect to a circuit board, without increasing the number of man-hours for working. <P>SOLUTION: An electronic key 1 (portable wireless key) has a circuit board 60 and an battery holder 70 provided in a key body 2. An end of the circuit board 60 is provided with notched portions 62-65 (insertion openings). The battery holder 70 comprises engaging protrusions 72-75 which are formed in the state of protruding toward the notched portions 62-65 of the circuit board 60 from a holder body 71, respectively. The engaging protrusion 72 has an outer peripheral surface 72b on the barycentric position side of the holder body 71 formed in a curved surface shape. The notched portion 62 has its inner peripheral surface 62a formed in a curved surface shape smaller in curvature than the outer peripheral surface 72b of the engaging protrusion 72, so as to regulate the displacement of the engaging protrusion 72 with respect to the circuit board 60. The notched portions 63-65 have inner peripheral surfaces 63a-65a formed in a planar shape, and permit the displacement of the engaging protrusions 73-75 with respect to the circuit board 60. <P>COPYRIGHT: (C)2012,JPO&INPIT |
