Remote controller

Claim 2

A remote controller comprising: a guide case; a slide member mounted on said guide case for axial movement but against rotation with respect to said guide case, said slide member having a threaded portion; a rotatable shaft rotatably mounted on said guide case for rotation but against axial movement with respect to said guide case, said rotatable shaft having a threaded portion in engagement with the threaded portion of said slide member for adjusting the position of said slide member with respect to said guide case; means for limiting the extent of rotation of said rotatable shaft with respect to said guide case to limit the extent of axial movement of said slide member with respect to said rotatable shaft; said slide member being of hollow construction, and said limiting means including a stop member fixed to said rotatable shaft and disposed in the interior of said slide member; first abutment means fixed to said slide member at a location adjacent to an end thereof and cooperating with said stop member and second abutment means fixed to said slide member at a location remote from said end thereof and cooperating with said stop member, said first and second abutment means being in the form of projections extending into the interior of said slide member.

Claim 3

A remote controller in a headlight beam adjusting device for a motor vehicle having a body and a headlight, the headlight beam adjusting device having pivotal mounting means for pivotally mounting the headlight on the vehicle body, means for biasing the headlight in one direction of tilt, and cable means connected at one terminal thereof to the mounting means for pulling the headlight in the opposite direction, the remote controller comprising: a guide case; a slide member mounted on said guide case for axial movement but against rotation with respect to said guide case, said slide member having a threaded portion; a rotatable shaft rotatably mounted on said guide case for rotation but against axial movement with respect to said guide case, said rotatable shaft having a threaded portion in engagement with the threaded portion of said slide member for adjusting the position of said slide member with respect to said guide case; means for limiting the extent of rotation of said rotatable shaft with respect to said guide case to limit the extent of axial movement of said slide member with respect to said rotatable shaft; said slide member being of hollow construction, and said limiting means including a stop member fixed to said rotatable shaft and disposed in the interior of said slide member; first abutment means fixed to said slide member at a location adjacent to an end thereof and cooperating with said stop member at a location remote from said end thereof and cooperating with said stop member, said first and second abutment means being in the form of projections extending into the interior of said slide member.

Claim 4

A remote controller in a headlight beam adjusting device for a motor vehicle having a body and a headlight, the headlight beam adjusting device having pivotal mounting means for pivotally mounting the headlight on the vehicle body, means for biasing the headlight in one direction of tilt, and cable means connected at one terminal thereof to the mounting means for pulling the headlight in the opposite direction, the remote controller comprising: a guide case; a slide member mounted on said guide case for axial movement but against rotation with respect to said guide case, said slide member having a threaded portion; a rotatable shaft rotatably mounted on said guide case for rotation but against axial movement with respect to said guide case, said rotatable shaft having a threaded portion in engagement with the threaded portion of said slide member for adjusting the position of said slide member with respect to said guide case; means for limiting the extent of rotation of said rotatable shaft with respect to said guide case to limit the extent of axial movement of said slide member with respect to said rotatable shaft; said slide member being of hollow construction, and said limiting means including a stop member fixed to said rotatable shaft and disposed in the interior of said slide member; first abutment means fixed to said slide member at a location adjacent to an end thereof and cooperating with said stop member at a location remote from said end thereof and cooperating with said stop member, said first and second abutment means being in the form of projections extending into the interior of said slide member.

Claim 5

A remote controller as claimed in claim 1 or 2, in which said slide member is in the form of a box without a cover and a bottom.

Claim 6

A remote controller as claimed in claim 1 or 2, in which said first abutment means includes two projections arranged so as to be abuttingly and simultaneously engageable with said stop at the positions diametrically opposed with respect to the center of rotation of said rotatable shaft.

Claim 7

A remote controller as claimed in claim 1 or 2, in which said rotatable shaft has an end disposed within said slide member, and in which said guide case as fixedly mounted thereto support means supporting said end of the rotatable shaft within said slide member, said support means including a pair of bearings formed with semi-cylindrical bearing surfaces on which said end of the rotatable shaft is rotatably supported.

Claim 8

A remote controller as claimed in claim 2, in which the terminal portion of said cable means adjacent said slide member is substantially coaxial with said rotatable shaft.
