A structure of vehicle electric equipment comprising: a housing for the vehicle electric equipment; an electric cable; a first connector provided on the electric cable; a second connector provided in the housing and detachably fitted to the first connector by moving the first connector in an attachment/detachment direction relative to the second connector; a short-circuit terminal provided in one of the first connector and the second connector; a pair of contacts provided in the other of the first connector and the second connector, the pair of contacts configured to be brought into contact with the short-circuit terminal to conduct each other in a fitting state where the first connector and the second connector are fitted, and to be separated from the short-circuit terminal and not to conduct each other in a non-fitting state where the first connector and the second connector are not fitted; an opening (6A, 6B), which is provided in the housing, for permitting access to components in the housing from an outside; a cover (7A, 7B) covering the opening (6A, 6B); a bolt screwed into a screw hole provided in the housing to fix the cover (7A, 7B) to the housing; and characterised by a restriction member fixed to the housing and restricting a removal of the bolt, wherein a first portion of the restriction member is disposed at a position overlapping with at least a part of a distal end in the attachment/detachment direction of the first connector when seen from the attachment/detachment direction and between the distal end of the first connector in a complete fitting state where the first connector are completely fitted to the second connector and a portion of the housing opposed to the distal end in the attachment/detachment direction, a second portion (52A, 52B) of the restriction member is positioned on an axial extension of the bolt fixing the cover (7A, 7B), and a sum of a gap (G 1) in an axial direction of the bolt between the bolt fixing the cover (7A, 7B) and the second portion (52A, 52B) and a distance (D 1) in the attachment/detachment direction between the distal end of the first connector in the complete fitting state and the first portion is smaller than a length (L 1) from an opening of the screw hole to a tip of the bolt fixing the cover (7A, 7B). a housing for the vehicle electric equipment; an electric cable; a first connector provided on the electric cable; a second connector provided in the housing and detachably fitted to the first connector by moving the first connector in an attachment/detachment direction relative to the second connector; a short-circuit terminal provided in one of the first connector and the second connector; a pair of contacts provided in the other of the first connector and the second connector, the pair of contacts configured to be brought into contact with the short-circuit terminal to conduct each other in a fitting state where the first connector and the second connector are fitted, and to be separated from the short-circuit terminal and not to conduct each other in a non-fitting state where the first connector and the second connector are not fitted; an opening (6A, 6B), which is provided in the housing, for permitting access to components in the housing from an outside; a cover (7A, 7B) covering the opening (6A, 6B); a bolt screwed into a screw hole provided in the housing to fix the cover (7A, 7B) to the housing; and characterised by a restriction member fixed to the housing and restricting a removal of the bolt, wherein a first portion of the restriction member is disposed at a position overlapping with at least a part of a distal end in the attachment/detachment direction of the first connector when seen from the attachment/detachment direction and between the distal end of the first connector in a complete fitting state where the first connector are completely fitted to the second connector and a portion of the housing opposed to the distal end in the attachment/detachment direction, a second portion (52A, 52B) of the restriction member is positioned on an axial extension of the bolt fixing the cover (7A, 7B), and a sum of a gap (G 1) in an axial direction of the bolt between the bolt fixing the cover (7A, 7B) and the second portion (52A, 52B) and a distance (D 1) in the attachment/detachment direction between the distal end of the first connector in the complete fitting state and the first portion is smaller than a length (L 1) from an opening of the screw hole to a tip of the bolt fixing the cover (7A, 7B).
