Claim 4

The device as defined in claim 1, wherein said driving means includes two electric motors and drive transmission means responsive to said two electric motors for tilting said mirror element, said means for tiltably supporting said mirror element being arranged to tiltably support said mirror element substantially at a center of said mirror element.

Claim 5

The device as defined in claim 3; further comprising the line which is formed as a harness line for controlling a drive of said electric motors.

Claim 6

The device as defined in claim 1; and further comprising: a housing enclosing said electric motors, said housing including a rear housing and a front housing engaging each other, said tiltably supporting means being formed at a center of said rear housing, said drive transmission means including two drive transmissions disposed in said housing and spaced apart from each other so as to define a right angle, said drive transmission further including two adjusting nuts movable back and forth at respective centers of said two drive transmissions.

Claim 7

The device as defined in claim 1, wherein said projections on one of said sidewalls have a triangular shape.

Claim 8

The device as defined in claim 1, wherein said slit defines an opening with an end, said triangular projections being formed to have a right-angled triangular cross-section with sides extending toward said end of said opening.

Claim 9

The device as defined in claim 1, wherein said labyrinths are formed to hold the line into position.

Claim 10

A rearview mirror device, comprising: a base; a mirror element with a reflecting surface; a mirror body supported said base; means for foldably supporting said mirror body and including an electric motor operated foldable door mirror and gear box in said mirror body; an actuating unit means secured fixed by within said mirror body, said actuating unit including means for tiltably supporting said mirror element, driving means for tilting said mirror element and a housing enclosing said driving means; and guiding means for guiding at least one line to said driving means and including a plurality of labyrinths leading to said driving means, said housing including a rear housing and a front house engaging each other, said guiding means being formed as labyrinth type guide inlets so as to constitute said plurality of labyrinths, said guide inlets including a plurality of lateral slits formed in said front housing, said slits having sidewalls with projections extending therefrom at predetermined intervals, said projections being disposed at positions displaced longitudinally of said slits, said line is extendable in a bent manner through said lateral slits to said driving means.

Claim 11

A rearview mirror device, comprising: a base; a mirror element with a reflecting surface; a mirror body supported said base; means for foldably supporting said mirror body and including an electric motor operated foldable door mirror and gear box in said mirror body; an actuating unit means secured fixed by within said mirror body, said actuating unit including means for tiltably supporting said mirror element, driving means for tilting said mirror element and a housing enclosing said driving means; and guiding means for guiding at least one line to said driving means and including a plurality of labyrinths leading to said driving means, said housing including a rear housing and a front house engaging each other, said guiding means being formed as labyrinth type guide inlets so as to constitute said plurality of labyrinths, said guide inlets including a plurality of lateral slits formed in said front housing, said slits having sidewalls with projections extending therefrom at predetermined intervals, said projections being disposed at positions displaced longitudinally of said slits, said line is extendable in a bent manner through said lateral slits to said driving means.

Claim 12

The device as defined in claim 9, wherein said labyrinths are to hold the line into position.

Claim 13

The device as defined in claim 9; and further comprising; the line, the line having an end; and a connector socket at said end of the line, said connector socket being arranged in one of said slits.
