A through hole 13B is formed in the top wall 13A of the support portion 13, and a through hole 13E is formed in each of the left side wall 13C and the right side wall 13D of the support portion 13 so as to overlap each other when viewed from the left and right direction X. The support portion 13 is in a state of accommodating most of the lower portion of the upper portion 11A of the vertical shaft 11 and covering the upper portion of the contact portion 12 from the upper side Z1. The vertical axis 11 is in a state of being inserted into the through hole 13B of the top wall 13A while maintaining the play.

The horizontal axis 14 is formed in a columnar shape extending in the left-right direction X. The left end portion 14A and the right end portion 14B of the horizontal axis 14 are formed in a small diameter compared to the intermediate portion 14C therebetween. An engaging portion 14D that protrudes to the right side X2 is integrally provided on the right end surface of the right end portion 14B. The engaging portion 14D is thinner than the right end portion 14B. The cross section of the engaging portion 14D when being cut along the flat surface orthogonal to the central axis J of the horizontal axis 14 is formed into a polygonal shape such as a quadrangle or a hexagon (see FIG. 5 described later).

Part of the state of the bite.

The procedure for adjusting the amount of protrusion D of the adjustment leg 9 from the lower surface portion 7A of the base portion 7 to the lower side Z2 will be described. In order to perform this adjustment, there is an operating member 17 operated by an operator. As shown in FIG. 3, the operation member 17 integrally includes a disk-shaped grip portion 17A that is gripped by an operator, and a tubular portion 17B that protrudes coaxially from a central portion of the grip portion 17A. The fitting hole 17C formed inside the tubular portion 17B has a cross-sectional shape that substantially matches the cross-sectional shape of the engaging portion 14D of the lateral axis 14 .

In a state in which the washing machine 1 is installed in a washing machine tray or the like and the lower end surface 8A of the fixed leg 8 and the lower end surface 12A of the contact portion 12 of the adjustment leg 9 are in contact with the installation surface S, the operator keeps bending as needed to see Adjust the leg 9. Then, the operator grasps the grip portion 17A of the operation member 17, causes the tubular portion 17B to approach the engagement portion 14D of the horizontal shaft 14, and inserts the engagement portion 14D into the fitting hole 17C. Thereafter, when the operator rotates the grip portion 17A in the circumferential direction K, the horizontal axis 14 rotates in the circumferential direction K. Then, since the rotational force of the horizontal axis 14 is converted into the force in the vertical direction Z and acts on the vertical axis 11 that meshes with the horizontal axis 14, the vertical axis 14 and the support portion 13 are relatively moved in the vertical direction Z. The shaft 11 will be lifted and lowered together with the contact portion 12. The longitudinal axis 11 and the transverse axis 14 constitute a screw jack configuration.

Specifically, when the horizontal axis 14 is rotated toward one side of the circumferential direction K, the vertical axis 11 and the contact portion 12 are lowered, and are away from the lower surface portion 7A of the base portion 7, so that the amount of protrusion D becomes large; When the shaft 14 is reversed, the vertical axis 11 and the contact portion 12 rise and approach the lower surface portion 7A, so that the amount of protrusion D becomes small. In the case of each of the fixed legs 8 (see FIG. 1), the amount of protrusion D is fixed, and if it is the adjustment leg 9, the amount of protrusion D changes. Therefore, in the washing machine 1, the amount of protrusion D of the adjustment leg 9 is freely adjusted, whereby the washing machine 1 can be tilt-adjusted and leveled. The support portion 13 that accommodates the vertical axis 11 and the horizontal axis 14 for adjusting the amount of protrusion D functions not only as a support for the horizontal axis 14, but also as a shield covering the vertical axis 11 and the horizontal axis 14. The operation member 17 may be detached from the engagement portion 14D after being tilt-adjusted, and stored in another storage location, or may be always connected to the card. The state of the joint 14D.

In connection with the tilt adjustment of the washing machine 1, the washing machine 1 includes the fitting portion 20 shown in FIG. The mounting portion 20 is formed in a flat plate shape having a thickness direction that coincides with the vertical direction Z. In FIG. 4, as an example, the mounting portion 20 is provided on the adjustment leg 9. In this case, the fitting portion 20 is integrated with the top wall 13A of the support portion 13 of the adjustment leg 9, and is in a state of extending substantially horizontally from the top wall 13A toward the front side Y1. At least the front end portion 20A of the mounting portion 20 is exposed from the recess portion 7B of the base portion 7 in which the adjustment leg 9 is accommodated, and is exposed from the base portion 7 toward the front side Y1 (see FIG. 2). A well-known level 21 is attached to the front end portion 20A from the upper side Z1. The level gauge 21 in this embodiment has a cap-shaped main body portion 21A whose upper surface is open and filled with a liquid therein, and a disk-shaped window portion 21B that blocks the inside of the main body portion 21A from the upper side Z1. The window portion 21B is transparent, and at least the lower surface is formed to be horizontally flat. In the center of the window portion 21B, for example, a circular mark 21C (see FIG. 12 described later) is provided. If the washing machine 1 reaches the level, the air bubbles P in the main body portion 21A are accommodated in the mark 21C, and therefore, if the window portion 21B of the level 21 is observed, it can be confirmed whether or not the washing machine 1 is horizontally disposed. The level gauge 21 may be fixed to the mounting portion 20 as a part of the washing machine 1, or may be separately stored as a separate component from the washing machine 1, and attached to the fitting portion 20 each time the tilt adjustment is performed.

In this way, the level gauge 21 attached to the fitting portion 20 provided on the adjustment leg 9 is disposed at the position of the unobtrusive lower side Z2 in the washing machine body 2 so as to approach the adjustment leg 9. In particular, since the fitting portion 20 is integrated with the adjustment leg 9, the level gauge 21 attached to the fitting portion 20 can be reliably disposed close to the adjustment leg 9. In this case, the operator can confirm the nearby level 21 without changing the posture of the body during the adjustment of the amount of protrusion D of the adjustment leg 9, and therefore, it can be confirmed by the level 21 whether the washing machine 1 is horizontally set. The amount of protrusion D of the adjustment leg 9 is adjusted. As a result, the work of accurately leveling the washing machine 1 can be easily performed.

In the above embodiment, the attachment portion 20 is provided on the adjustment leg 9, but the attachment portion 20 may be provided in the base portion 7 as in the first modification shown in FIGS. 5 and 6. In the following, the same portions as those in the previous portions are denoted by the same reference numerals, and the detailed description thereof will be omitted. In addition, in FIGS. 5 and 6, for convenience of explanation, a part of each of the base portion 7 and the fitting portion 20 is illustrated in a cross section.

The fitting portion 20 of the first modification is formed into a substantially rectangular plate shape. For example, the right side wall 7E of the base portion 7 is formed with an opening 7F having substantially the same size as the fitting portion 20 and communicating with the inside of the base portion 7. One end portion of each of the front and rear sides of the fitting portion 20 is formed so as to protrude away from each other in the front-rear direction Y. The rotating shaft 20B is taken out. The rotation shaft 20B of the front side Y1 is inserted into the insertion hole 7G formed at the lower end portion of the peripheral portion of the front side Y1 in the opening 7F, and the rotation shaft 20B of the rear side Y2 is inserted into the peripheral portion of the rear side Y2 formed in the opening 7F. The other end of the lower end is inserted into the hole 7G. Thereby, the fitting portion 20 is supported by the base portion 7, and is rotatable about the pair of front and rear rotating shafts 20B. In detail, the fitting portion 20 is rotated between an open position and a closed position, which is substantially horizontally extended from the right side wall 7E to the right side X2 as indicated by a solid line, the closed position being as indicated by a broken line, It is substantially vertical and blocks the opening 7F. The level 21 is fixed to the upper surface of the fitting portion 20 when it is substantially horizontal. Therefore, when the fitting portion 20 is disposed at the open position, the level gauge 21 is disposed to be exposed from the right side wall 7E, and the window portion 21B of the level gauge 21 is exposed to the upper side Z1. On the other hand, when the fitting portion 20 is rotated to the closed position, the level 21 is stored in the base portion 7 (refer to Fig. 6).

In the first modification, when the horizontal operation of the washing machine 1 is performed, it is possible to confirm whether or not the washing machine 1 is horizontally set by the level gauge 21 attached to the fitting portion 20 which is pulled from the base portion 7 and is in the open position, after the completion of the work. By rotating the fitting portion 20 to the closed position, it can be stored in the base portion 7 together with the level gauge 21.

When the mounting portion 20 is provided in the base portion 7 as in the first modification, the mounting portion 20 can be fixed to the right side wall 7E of the base portion 7, for example, and integrated with the base portion 7 without the fitting portion. 20 is configured to be rotatable.

The mounting portion 20 can also be detachably attached to the washing machine 1 without being provided to the base portion 7 of the washing machine 1 or the adjusting leg 9 as described above. In this case, after the work for leveling the washing machine 1 is completed, the fitting portion 20 can be detached and placed together with the level gauge 21. As shown in FIGS. 7 and 8, the detachable mounting portion 20 integrally includes a rectangular plate-shaped main body portion 20C, and the first engaging portion 20D forms one end portion of the main body portion 20C in the longitudinal direction; The second engaging portion 20E is provided on both sides of the first engaging portion 20D in the short dimension direction of the main body portion 20C. An arcuate notch 20F is formed in one end edge of the first engaging portion 20D in the longitudinal direction of the main body portion 20C. The pair of second engagement portions 20E are formed in a claw shape that is cut from the main body portion 20C in the thickness direction of the main body portion 20C.

Next, a description will be given of a second modification and a third modification of the washing machine 1 to which the detachable fitting portion 20 is applied. In the washing machine 1 of the second modification shown in FIG. 9 and FIG. 10, the bottom plate 7C of the recess portion 7B accommodating the adjustment leg 9 in the base portion 7 is formed with the number of the mounting portions 20 in the left-right direction X. The two engaging portions 20E are the same, that is, two through holes 7H are formed. Operator in the washing machine 1 Before the tilt adjustment, the first engaging portion 20D of the mounting portion 20 is inserted into the through hole 7H one by one along the lower surface of the bottom plate 7C. Then, the first engaging portion 20D and the respective second engaging portions 20E sandwich the bottom plate 7C, whereby the fitting portion 20 is attached to the base portion 7. In the attached mounting portion 20, the main body portion 20C extends substantially horizontally from the bottom plate 7C toward the front side Y1, and at least the front end portion of the main body portion 20C is exposed from the concave portion 7B and exposed from the base portion 7 toward the front side Y1. The level 21 is attached to the front end portion of the main body portion 20C from the upper side Z1. When the tilt adjustment of the washing machine 1 is completed, the operator removes the second engaging portions 20E of the fitting portion 20 from the through holes 7H, thereby disengaging the fitting portion 20 from the base portion 7.

In the washing machine 1 of the third modification shown in FIG. 11 and FIG. 12, in the top wall 13A of the support portion 13 of the adjustment leg 9, a number of second engaging portions of the fitting portion 20 are formed side by side in the left-right direction X. The same through hole 13F of 20E. Before the operator adjusts the tilt of the washing machine 1, the first engaging portion 20D of the fitting portion 20 is placed along the upper surface of the top wall 13A, and the second engaging portions 20E are fitted one by one into the through hole 13F. Then, the first engaging portion 20D and the second engaging portions 20E sandwich the top wall 13A, whereby the fitting portion 20 is attached to the supporting portion 13. The longitudinal axis 11 of the adjustment leg 9 is fitted into the notch 20F of the first engagement portion 20D, whereby the attachment portion 20 is attached to the support portion 13 without colliding with the longitudinal axis 11 (refer to Fig. 12). In the attached fitting portion 20, the main body portion 20C extends substantially horizontally from the top wall 13A toward the front side Y1, and at least the front end portion of the main body portion 20C is exposed from the concave portion 7B of the base portion 7 and is forwardly side from the base portion 7 Y1 is exposed. The level 21 is attached to the front end portion of the main body portion 20C from the upper side Z1. When the tilt adjustment of the washing machine 1 is completed, the operator removes the second engaging portions 20E of the fitting portion 20 from the through holes 13F, thereby disengaging the fitting portion 20 from the adjusting legs 9.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims.

For example, in the adjustment leg 9, the screw portion 11D is formed on the outer peripheral surface 11C of the vertical shaft 11, and the vertical shaft 11 and the contact portion 12 are moved up and down by rotating the horizontal shaft 14 having the intermediate portion 14C engaged with the screw portion 11D. Instead of the screw portion 11D, a rack (not shown) may be provided on the outer peripheral surface 11C. Thereby, the vertical shaft 11 and the contact portion 12 can be moved up and down by the rack and pinion mechanism including the rack and the intermediate portion 14C.

Further, as in the washing machine 1 of the fourth modification shown in FIG. 13, an adjustment leg 9 having a structure different from that of the aforementioned screw jack structure can be used. The adjustment leg 9 of the fourth modification has the aforementioned longitudinal axis 11 and the contact portion 12 and the loosening member 25. A screw hole 7I is formed in the bottom plate 7C of the base portion 7 in which the recess 7B of the adjustment leg 9 is accommodated. The vertical shaft 11 is inserted into the screw hole 7I, and the screw portion 11D of the vertical shaft 11 is engaged with the screw portion (not shown) of the screw hole 7I.
