## Abstract

An assembled body attachable to an attached body includes: a main body member made of a rigid material; an annular seal member made of a material that is more easily deformed than the main body member, and assembled on the main body member to close a gap between the main body member and the attached body; and a cover member assembled on the main body member. The main body member is formed with an attachment portion to be disposed inside the attached body, and the cover member is installed on the attachment portion. A seal member attachment region is assigned between a part of the main body member and the cover member, and the seal member attachment region is defined at least by an exposed surface of the attachment portion that is not covered by the cover member and one end surface of the cover member.

## Claims

### Claim 1

An assembled body attachable to an attached body, the assembled body comprising:
a main body member made of a rigid material and forming a main part of the assembled body;
an annular seal member made of a material that is more easily deformed than the main body member, and assembled on the main body member to close a gap between the main body member and the attached body; and
a cover member assembled on the main body member,
wherein the main body member is formed with an attachment portion to be disposed inside the attached body, and the cover member is installed on the attachment portion so as to cover a part of an outer periphery of the attachment portion, and
wherein a seal member attachment region extending annularly along the outer periphery of the attachment portion is assigned between a part of the main body member and the cover member installed on the attachment portion of the main body member, and the seal member attachment region is defined at least by an exposed surface of the attachment portion that is not covered by the cover member and one end surface of the cover member.

### Claim 2 (depends on 1)

The assembled body according to claim 1,
wherein the annular seal member attachment region has a substantially U-shaped cross section.

### Claim 3 (depends on 1)

The assembled body according to claim 1,
wherein the main body member has a step portion having a surface which faces one end portion of the cover member installed on the attachment portion, and
wherein the seal member attachment region is provided between the one end portion of the cover member and the step portion of the main body member.

### Claim 4 (depends on 1)

The assembled body according to claim 1,
wherein at least a part, on which the cover member is installed, of the attachment portion of the main body member has a tapered shape.

### Claim 5 (depends on 1)

The assembled body according to claim 1, further comprising:
a second seal member.

### Claim 6 (depends on 5)

The assembled body according to claim 5, further comprising:
a second cover member provided correspondingly to the second seal member,
wherein a second seal member attachment region for the second seal member is provided between the cover member and the second cover member.

### Claim 7 (depends on 1)

The assembled body according to claim 1,
wherein the cover member is fixed to the attachment portion of the main body member by an adhesive.

### Claim 8 (depends on 1)

The assembled body which functions as a terminal block according to claim 1, further comprising:
a bus bar functioning as a conductive terminal member,
wherein the main body member includes a plate-shaped base portion and a protruding portion protruding from the base portion,
wherein a part of the bus bar is embedded in the main body member, and another part of the bus bar protrudes outward from the protruding portion of the main body member and is exposed, and
wherein the cover member is provided around the protruding portion of the main body member.
