## Abstract

A vehicle roller finger follower may include a main body including a supporting portion and a wall portion having one end portion integrally extending in a width direction of the supporting portion at both sides; and a pallet portion formed toward an outside in the width direction of the main body at the other end portion of the wall portion, wherein the wall portion has a mounting hole to mount a bearing, and a connection portion is formed at a lower portion of the wall portion at a position corresponding to the mounting hole.

## Claims

### Claim 1

A vehicle roller finger follower apparatus comprising:
a main body including a supporting portion and a wall portion having a first end portion integrally extending in a width direction of the supporting portion at a first side and a second side thereof; and
a pallet portion formed toward an outside in a width direction of the main body at a second end portion of the wall portion,
wherein the wall portion has a mounting hole to mount a bearing,
wherein a connection portion is formed at a lower portion of the wall portion at a position corresponding to the mounting hole,
wherein a first end portion of the connection portion is formed to be inclined downward by a predetermined angle from the supporting portion toward the pallet portion with respect to an imaginary horizontal line passing through the supporting portion and a lower portion of the pallet portion, and
wherein the connection portion connects the lower portion of the wall portion and prevents a contact thereof with the bearing so that a load is dispersed while the connection portion supports the load acted from the bearing to the wall portion.

### Claim 2 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
the connection portion integrally extends toward a lower portion from the wall portion.

### Claim 3 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
a second end portion of the connection portion is integrally connected to the supporting portion.

### Claim 4 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
the connection portion is formed of a cross-section having a “⊏” character shape.

### Claim 5 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
the pallet portion extends from an external surface of the wall portion.

### Claim 6 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
the pallet portion is bent from a first end portion thereof connected to the wall portion to a second end portion thereof.

### Claim 7 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
a lower surface of a protruded end portion of the pallet portion is formed of a valve contacting surface protruded to be rounded toward the lower portion.

### Claim 8 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
the wall portion is bent vertically toward an upper portion of the supporting portion.

### Claim 9 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
the main body, the pallet part, and the connection portion are integrally formed.

### Claim 10 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein
the bearing is mounted to the mounting hole through a connection shaft to be rotatable.

### Claim 11 (depends on 1)

The vehicle roller finger follower apparatus of claim 1, wherein the first end portion of the connection portion is open toward the pallet portion along the imaginary horizontal line.
