## Abstract

A manufacturing method of a laundry machine is disclosed. The manufacturing method of the laundry machine includes a suspension preparing step configured to prepare a suspension unit (40) configured to flexibly support a drum (30), a tub rear securing step configured to secure a tub rear (120) to the suspension unit (40), a drum securing step configured to a shaft (351) or the drum (30) to the suspension unit (40) via an inside of the tub rear (120), a tub front coupling step configured to couple a tub front (100) to the tub rear (120), a tub seating step configured to seat the tub front (100) and the tub rear (120) in a cabinet cabinet base (600)m and a suspension securing step configured to secure the suspension unit to the cabinet base (600).

## Claims

### Claim 1

A manufacturing method of a laundry machine comprising:
installing a tub, a drum and a suspension unit to a cabinet base, the suspension unit being configured to suspend vibration of the chum, the tub being seated on a base by supporters, and having a rear portion, and a tub back, the suspension unit comprising a shaft, a bearing housing, and a bracket;
then connecting a rear gasket between the rear portion of the tub and the tub back; and
then assembling a cabinet front, a cabinet left, a cabinet right, and a cabinet rear to the cabinet base,
wherein the tub is installed to stand alone on the base by the supporters in the step of installing the tub, the drum, and the suspension unit to the cabinet.

### Claim 2 (depends on 1)

The manufacturing method as claimed in claim 1, wherein the tub and the drum are installed to the cabinet base such that suspensions, including the suspension unit, are installed to the base, in the step of installing the tub, the drum, and the suspension unit.

### Claim 3 (depends on 1)

The manufacturing method as claimed in claim 1, wherein the tub back and the cabinet rear are fixed to each other.

### Claim 4 (depends on 1)

The manufacturing method as claimed in claim 1, wherein the cabinet front is fixed to the base, and a front side of the tub and the cabinet front are fixed to each other.

### Claim 5 (depends on 1)

The manufacturing method as claimed in claim 1, wherein the cabinet left and the cabinet right are fixed to the base so as to be adjacent to both sides of the tub.

### Claim 6 (depends on 1)

The manufacturing method as claimed in claim 1, wherein each of the tub and the drum comprises an opening formed in a front part thereof to load laundry therein.

### Claim 7 (depends on 1)

The manufacturing method as claimed in claim 1, wherein the tub is supported more rigidly with respect to vibration generated in the drum than the drum is supported.
