Abstract: An arm wearable device including a case, a module which has a brittle member and is provided in the case, and a plurality of holding portions which holds the module in the case such that flexural deformation of the module is restricted to deformation where a virtual straight line extending in a longitudinal direction of the brittle member serves as a center line.

Abstract: An electronic device including a first contact member, a second contact member which is arranged opposing the first contact member, a resilient conductive member which electrically connects the first contact member with the second contact member, and a resilient guide holding member having a guide portion which guides the resilient conductive member in opposing directions of the first contact member and the second contact member, and a resilient holding portion which holds the guide portion such that the guide portion is resiliently movable in the opposing directions of the first contact member and the second contact member.

Abstract: A drip-proof connecting mechanism, comprising: a shaft body having a cylindrical surface; a box-shaped body having an opening through which the shaft body is inserted; a ring-shaped member disposed to cover the cylindrical surface of the shaft body; a first water stopping body disposed to cover the cylindrical surface of the shaft body and to be sandwiched between the ring-shaped member and the cylindrical surface of the shaft body; and a second water stopping body disposed to cover an outer circumferential surface of the ring-shaped member and to closely contact the ring-shaped member and the box-shaped body.
