## Abstract

An attaching structure for a motor vehicle includes a cylinder head; an EGR valve arranged adjacent to the cylinder head; a bracket including a first portion attached to the cylinder head, a second portion attached to the EGR valve, and a low rigidity portion arranged between the first portion and the second portion, the low rigidity portion having a rigidity less than remaining portions of the bracket; and a vehicle component arranged adjacent to the EGR valve. The low rigidity portion is formed to break when the EGR valve receives a shock load from the vehicle component.

## Claims

### Claim 1

An attaching structure for a motor vehicle, comprising:
a cylinder head;
an EGR valve arranged adjacent to the cylinder head;
a bracket including
a first portion attached to the cylinder head,
a second portion attached to the EGR valve, and
a low rigidity portion arranged between the first portion and the second portion, the low rigidity portion having a rigidity less than remaining portions of the bracket; and
a vehicle component arranged adjacent to the EGR valve,
wherein the low rigidity portion is configured to break when the EGR valve receives a shock load from the vehicle component.

### Claim 2 (depends on 1)

The attaching structure according to claim 1, wherein the bracket further comprises an initial breaking portion where the bracket initially breaks from the shock load.

### Claim 3 (depends on 2)

The attaching structure according to claim 2, wherein the initial breaking portion is a notch formed continuously to the low rigidity portion.

### Claim 4 (depends on 3)

The attaching structure according to claim 3, wherein the low rigidity portion is a groove.

### Claim 5 (depends on 4)

The attaching structure according to claim 4, wherein the vehicle component is a brake booster of the motor vehicle.

### Claim 6 (depends on 5)

The attaching structure according to claim 5, wherein the bracket is configured to break at the low rigidity portion so that a distance between the cylinder head and the EGR valve changes to absorb the shock load from the brake booster.

### Claim 7 (depends on 1)

The attaching structure according to claim 1, wherein the bracket is formed of a resin.
