Claim 1
Independent Claim
187 words
An electric remote control mirror apparatus including a mirror (28), a mirror Bcdy (29) fixing said mirror, a mirror hcusing (26) receiving said mirror body, pivot connection (30) for pivotably supporting said mirror body, two ball bases (35) located on respective lines perpendicular to each other and crossing at said pivot connection, threaded rods (31) each of which has a ball (32) at the end thereof and a screw on the peripheral surface thereof, screw members(47) for being connected to said threaded rod respectively, transmission means (53) for transmitting driving force to said screw members, and electric motors (52) for driving said screw members through said transmission means, CHARACTERIZED IN THAT said screw members each has a boss-like protrusion (47a) provided with a pair of slots (47b), one of the slots being twisted in relative to the other of the slots by the angle corresponding_ to one pitch of the screw of the threaded rod, and the spring member has two legs twisted to each other and adapted to be inserted into the slots so as to pinch the valley of the screw of the threaded rod.

An electric remote control mirror apparatus including a mirror (28), a mirror Bcdy (29) fixing said mirror, a mirror hcusing (26) receiving said mirror body, pivot connection (30) for pivotably supporting said mirror body, two ball bases (35) located on respective lines perpendicular to each other and crossing at said pivot connection, threaded rods (31) each of which has a ball (32) at the end thereof and a screw on the peripheral surface thereof, screw members(47) for being connected to said threaded rod respectively, transmission means (53) for transmitting driving force to said screw members, and electric motors (52) for driving said screw members through said transmission means, CHARACTERIZED IN THAT said screw members each has a boss-like protrusion (47a) provided with a pair of slots (47b), one of the slots being twisted in relative to the other of the slots by the angle corresponding_ to one pitch of the screw of the threaded rod, and the spring member has two legs twisted to each other and adapted to be inserted into the slots so as to pinch the valley of the screw of the threaded rod.
Claim 3
Dependent Claim
68 words
An electric remote control mirror apparatus according to claim 1, characterized in that each leg of the spring member has outwardly convexed portion (51a) formed so as to fit the valley of the screw of the threaded rod, and the inner wall of the slot is formed so as to receive the convexed portion when the legs are subject to overtorque through the threaded rod , expanding outwardly.
Claim 4
Dependent Claim
47 words
An electric remote control mirror apparatus according to claim 2, characterized in that said legs of the spring member have outwardly extended portions (51b), provided continuous with the convexed portions, respectively, thereby preventing from dropping out of the slots when subject to overtorque through the threaded rod.
