## Abstract

A fluid control valve includes a valve unit, a valve casing, and a secondary molded member. The valve casing houses the valve unit therein and includes a first connection pipe part and a second connection pipe part. The first connection pipe part has a hollow pipe shape with a first engagement part. The second connection pipe part has a hollow pipe shape with a second engagement part. The first connection pipe part is connected to the second connection pipe part. The secondary molded member is made of a resin material and covers the first engagement part and the second engagement part to prevent the first connection pipe part from being detached from the second connection pipe part.

## Claims

### Claim 1

A fluid control valve, comprising:
a valve unit;
a valve casing housing the valve unit therein, wherein the valve casing includes a first connection pipe part and a second connection pipe part, wherein the first connection pipe part has a hollow pipe shape with a first engagement part, wherein the second connection pipe part has a hollow pipe shape with a second engagement part, wherein the first connection pipe part is connected to the second connection pipe part; and
a secondary molded member made of a resin material and covering the first engagement part and the second engagement part to prevent the first connection pipe part from being detached from the second connection pipe part.

### Claim 2 (depends on 1)

The fluid control valve according to claim 1, wherein at least one of the first connection pipe part and the second connection pipe part has a projection extending along an edge of the secondary molded member.

### Claim 3 (depends on 1)

The fluid control valve according to claim 1, wherein the first connection pipe part and the second connection pipe part are made of a resin material having a melting point lower than the secondary molded member; and
wherein the secondary molded member is integrally joined with both the first connection pipe part and the second connection pipe part.

### Claim 4 (depends on 1)

The fluid control valve according to claim 1, wherein the first connection pipe part and the second connection pipe part hold a separate member therebetween.

### Claim 5 (depends on 1)

The fluid control valve according to claim 1, further comprising:
a sealing member disposed between the first connection pipe part and the second connection pipe part for sealing therebetween.

### Claim 6 (depends on 1)

The fluid control valve according to claim 1, wherein the first engagement part extends in the circumferential direction of the first connection pipe part.

### Claim 7 (depends on 6)

The fluid control valve according to claim 6, wherein the first engagement part extends continuously along the whole circumference of the first connection pipe part.

### Claim 8 (depends on 1)

The fluid control valve according to claim 1, wherein the second engagement part extends in the circumferential direction of the second connection pipe part.

### Claim 9 (depends on 8)

The fluid control valve according to claim 8, wherein the second engagement part extends continuously along the whole circumference of the second connection pipe part.

### Claim 10 (depends on 1)

The fluid control valve according to claim 1, wherein the secondary molded member has a ring shape and is mounted around the first connection pipe part.
