Document Type and Number:
WIPO Patent Application WO/2023/079873
Kind Code:
A1
Abstract:
[Problem] To provide a mechanism for a smart key storage case for preventing a relay attack, the mechanism allowing the inner space of the smart key storage case to be simply closed by one hand, while achieving the signal-blocking effect of the smart key storage case. [Solution] A smart key storage case according to the present application for preventing a relay attack comprises a housing having, in a part thereof, an opening communicating with an internal space, and an open/close body closing the opening in an openable/closable manner. At least one of an inner surface and an outer surface of the housing is composed of a member that blocks radio waves transmitted from a key placed in the internal space and/or radio waves received by the key. A lower wall body of the housing includes an inclined surface. This configuration provides the effects that encasement can be performed simply by one hand without performing cumbersome operations, such as detaching a lid, and that a high blocking effect can be obtained.
