Abstract

In an opening/closing mechanism of a sunroof apparatus, an engaged portion engaged with a cam groove smoothly slides on upper and lower cam surfaces of a cam groove, and stiffness to support a roof panel is increased at low costs. The engaged portion includes a first sliding portion having a convex curve facing upward and sliding on the upper cam surface of the cam groove, and a second sliding portion coupled to the first sliding portion at a front or a rear of a vehicle, having a convex curve facing downward, and sliding on the lower cam surface of the cam groove.

First claim

What is claimed is:

1. A sunroof apparatus comprising:
a roof panel provided in an opening formed in a fixed roof of a vehicle; and
an opening/closing mechanism opening and closing the opening by at least obliquely moving the roof panel relative to the opening in an vertical direction, wherein the opening/closing mechanism includes a support member fixed to the roof panel, a guide rail fixed to the fixed roof, and extending in a longitudinal direction of the vehicle, a movable member movable along the guide rail in the longitudinal direction of the vehicle, a cam groove provided in the support member, and including an upper cam surface and a lower cam surface facing each other in the vertical direction and extending in the longitudinal direction of the vehicle, and an engaged portion provided in the movable member to project in a vehicle width direction, being engaged with the cam groove, and relatively sliding on the upper and lower cam surfaces of the cam groove by movement of the movable member,
relative slide movement of the engaged portion on the upper and lower cam surfaces of the cam groove obliquely moves the roof panel relative to the opening in the vertical direction,
the engaged portion includes a first sliding portion having a convex curve facing upward, and sliding on the upper cam surface of the cam groove, and a second sliding portion coupled to the first sliding portion, having a convex curve facing downward, and sliding on the lower cam surface of the cam groove,
wherein the engaged portion is a metal member, and bended in a substantial S shape when viewed from the vehicle width direction;
wherein the member provided with the cam groove is formed by integrally molding a resin member and a metal plate, and the upper and lower cam surfaces of the cam groove are made of the resin member;
wherein the support member is formed by insert molding of the metal plate into part of the resin member, and
wherein the support member is provided with a lower wall an upper wall located above the lower wall and extending substantially in parallel with the lower wall, and a side wall, which connects the lower wall to the upper wall, the lower wall, the upper wall and the side wall forming the cam groove.

2. The sunroof apparatus of claim 1 , wherein the metal plate extends in the vertical direction in the middle of the support member and bends outward at the both upper and lower ends.

3. The sunroof apparatus of claim 1 , wherein an upper portion of the lower wall, an outer portions of the upper wall and the side wall are part of the resin member.

4. The sunroof apparatus of claim 1 , wherein the engaged portion is a metal plate.

5. The sunroof apparatus of claim 4 , wherein the engaged portion is integrally formed with a slider.
