Abstract

In a sunroof device, a driving shoe includes a first plate being made of metal and including a first engaging wall engaging with a first guide portion of a support member, a second plate being made of metal and including a second engaging wall engaging with a second guide portion of the support member, and a sliding portion sliding with a guide rail. The driving shoe, by moving along the guide rail with the first engaging wall and the second engaging wall engaging with the first guide portion and the second guide portion, respectively, causes a rear edge portion of a movable panel to ascend or descend via the support member. In the driving shoe, the first plate and the second plate are coupled to each other in a width direction by the sliding portion.

First claim

The invention claimed is:

1. A sunroof device comprising:
guide rails extending in a vehicle front-rear direction at both edge portions in a vehicle width direction of a roof opening portion formed in a roof of a vehicle;
support members supporting a movable panel opening and closing the roof opening portion, and being configured in a movable manner with respect to the guide rails; and
driving shoes moving along the guide rails while engaging with the support members, wherein
each of the support members includes a first guide portion and a second guide portion respectively formed on both sides in the vehicle width direction of the support member,
each of the driving shoes includes a first plate being made of metal and including a first engaging portion engaging with the first guide portion, a second plate being made of metal and including a second engaging portion engaging with the second guide portion, and a sliding portion sliding with one of the guide rails, and, by moving along one of the guide rails with the first engaging portion and the second engaging portion engaging with the first guide portion and the second guide portion, respectively, causes a rear edge portion of the movable panel to ascend or descend via one of the support members,
the first plate and the second plate are coupled to each other in the vehicle width direction by the sliding portion,
the first plate includes a first sidewall defining a first coupling hole and a first engagement hole each extending through the first sidewall along the vehicle width direction,
the second plate includes a second sidewall defining a second coupling hole and a second engagement hole each extending through the second sidewall along the vehicle width direction, and
each of the first coupling hole and the second coupling hole is configured to receive a guide shaft.

2. The sunroof device according to claim 1 , wherein:
the sliding portion is formed of a resin material, and
the first plate, the second plate, and the sliding portion are insert molded together such that the sliding portion covers a part of the first plate and covers a part of the second plate so as to integrate the sliding portion with the first plate and the second plate and to couple the first plate and the second plate to one another.

3. The sunroof device according to claim 2 , wherein
in the first plate and the second plate, a first through-hole and a second through-hole are formed, respectively, in a direction crossing the vehicle front-rear direction, and
the first through-hole and the second through-hole are filled with the resin material forming the sliding portion.

4. A method for manufacturing a driving shoe of the sunroof device according to claim 1 , the method comprising:
a first forming step of forming the first plate and the second plate individually;
an arrangement step of arranging the first plate and the second plate in a die; and
a second forming step of, by curing liquid resin injected in the die, forming the sliding portion.

5. A method for manufacturing a driving shoe of the sunroof device according to claim 2 , the method comprising:
a first forming step of forming the first plate and the second plate individually;
an arrangement step of arranging the first plate and the second plate in a die; and
a second forming step of, by curing liquid resin injected in the die, forming the sliding portion,
wherein in the second forming step, the first plate, the second plate, and the sliding portion are insert molded together.

6. A method for manufacturing a driving shoe of the sunroof device according to claim 3 , the method comprising:
a first forming step of forming the first plate and the second plate individually;
an arrangement step of arranging the first plate and the second plate in a die; and
a second forming step of, by curing liquid resin injected in the die, forming the sliding portion, wherein
in the second forming step, the first plate, the second plate, and the sliding portion are insert molded together and the liquid resin fills the first through-hole and the second through-hole.

7. The method for manufacturing the driving shoe of the sunroof device according to claim 4 , wherein
the sunroof device is a sunroof device including the guide shaft, the guide shaft coupling the first plate and the second plate to each other in the vehicle width direction,
the method further comprises a coupling step of, after the second forming step, by inserting the guide shaft into a first coupling hole formed in the first plate and a second coupling hole formed in the second plate, coupling the first plate and the second plate to each other, and
the arrangement step arranges the first plate and the second plate in the die in such a way that an axis of the first coupling hole of the first plate coincides with an axis of the second coupling hole of the second plate.

8. The method for manufacturing the driving shoe of the sunroof device according to claim 5 , wherein
the sunroof device is a sunroof device including the guide shaft, the guide shaft coupling the first plate and the second plate to each other in the vehicle width direction,
the method further comprises a coupling step of, after the second forming step, by inserting the guide shaft into a first coupling hole formed in the first plate and a second coupling hole formed in the second plate, coupling the first plate and the second plate to each other, and
the arrangement step arranges the first plate and the second plate in the die in such a way that an axis of the first coupling hole of the first plate coincides with an axis of the second coupling hole of the second plate.

9. The method for manufacturing the driving shoe of the sunroof device according to claim 6 , wherein
the sunroof device is a sunroof device including the guide shaft, the guide shaft coupling the first plate and the second plate to each other in the vehicle width direction,
the method further comprises a coupling step of, after the second forming step, by inserting the guide shaft into a first coupling hole formed in the first plate and a second coupling hole formed in the second plate, coupling the first plate and the second plate to each other, and
the arrangement step arranges the first plate and the second plate in the die in such a way that an axis of the first coupling hole of the first plate coincides with an axis of the second coupling hole of the second plate.

10. The sunroof device according to claim 1 , wherein
the first plate comprises a first engaging wall and the second plate comprises a second engaging wall, the first engaging wall defining the first engaging portion and the second engaging wall defining the second engaging portion, and
each of the first engaging wall and the second engaging wall is curved in a respective arc shape when viewed in the vehicle width direction.

11. The sunroof device according to claim 10 , wherein
the first engaging wall is curved such that at an intermediate portion of the first engaging wall in the vehicle front-rear direction is positioned lower than a front edge portion of the first engaging wall and a rear edge portion of the first engaging wall, and
