Abstract
A curved portion formed on a guide rail is sandwiched between an inscribed projection and a circumscribed projection. Therefore, a carrier plate can turn around a curving center of the inscribed projection. Even when the guide rail is twisted, an element to be guided and the carrier plate can turn in accordance with the twist, a prying force is reduced, and the carrier plate can vertically move smoothly.
Claims10
A vehicular window regulator comprising:
- a guide rail which is fixed to a door and extended in a vertical direction;
- a carrier plate;
- and
- an element to be guided mounted on the carrier plate and guided by the guide rail so as to allow vertical movement along the guide rail, wherein
- the guide rail is provided with a curved portion having a substantially constant arc cross section in a longitudinal direction,
- the element to be guided is provided with an inscribed projection having a curved surface which is inscribed with the curved portion and a circumscribed projection which is circumscribed with the curved portion, and
- the curved portion is sandwiched between the inscribed projection and the circumscribed projection, and also a gap is formed between the guide rail and the element to be guided, thereby allowing the carrier plate to horizontally rotate about a curving center of the curved portion.

A vehicular window regulator comprising:
- a guide rail which is fixed to a door of a vehicle and extended in a vertical direction;
- and
- a carrier plate which vertically moves along the guide rail, while being guided by the guide rail, wherein
- the guide rail has a substantially hat-shaped cross section protruding in a widthwise direction of the vehicle,
- the guide rail is provided with a curved portion having a substantially constant arc cross section in a longitudinal direction,
- the carrier plate has a plate portion extending along in the vertical direction and in a longitudinal direction of the vehicle, and three projections protruding from the plate portion on center, front and rear sides thereof in a widthwise direction of the vehicle,
- the projection on the center side is provided with one of an inscribed projection having a curved surface which is inscribed with the curved portion and a circumscribed projection which is circumscribed with the curved portion, and the projection on either the front or rear side is provided with the other of the inscribed projection and the circumscribed projection, and
- the curved portion is sandwiched between the inscribed projection and the circumscribed projection, and also a gap is formed between the guide rail and each of the three projections, thereby allowing the carrier plate to horizontally rotate about a curving center of the curved portion.
