A straight plate-shaped bearing bracket (12) is suspended from the rear edge of (8), and both bearing brackets (11, 12) are rotatably connected by a shaft (13) to form a hinge (14). The axis (13) of the hinge (14) is offset from the front edge of the rear half (9) from the front, so that the front lid (6) is folded upright as shown in FIG. The trailing edge of 8) is higher than the leading edge of the latter half (9), and as shown in FIG.
When viewed from the front of (1), the hinge of the upper lid (6) in a folded state
The part (14) is set so as to be hidden by the rear edge of the front half part (8) so as not to be seen.

A backrest (15) is provided at the rear edge of the toilet body (2).
Is installed. The backrest (15) comprises an upper side (16) and both sides (17, 17), and as shown in FIG.
(17, 17) A mounting cylinder (18, 18) extends from the lower end. As shown in FIG. 8, the mounting cylinder (18) is provided with a pair of front and rear cut grooves (19) from the lower end, and claws (20) are protruded from left and right of the lower end of the mounting cylinder (18). I have.

As shown in FIGS. 4 and 8, the backrest (1
The mounting cylinders (18, 18) on both sides (17, 17) of 5) are
It is inserted into the mounting outer cylinder (21) which is open at the rear part on both sides of the upper surface of (2). As shown in FIGS. 9 and 10, the mounting outer cylinder (21) is provided with ribs (22, 23, 24, 25) in the toilet body (2).
Is reinforced and supported by the core tube from the bottom center
A notch (27) is provided on both the left and right sides of the bottom, and a mounting cylinder (18) on both sides (17) of the backrest (15) is provided on the mounting outer cylinder (21). 10, the claw (20) of the mounting cylinder (18) engages with the notch (27) of the mounting outer cylinder (21) as shown in FIG.

In the both side portions (17, 17), a fixed tube (28) is inserted into the mounting tube (18) from above as shown in FIGS. 8, 9, and 10. A substrate (29) is provided at an upper end of the fixed cylinder (28), and a pair of front and rear cut grooves (30, 30) are provided from a lower end. A claw (31) is provided at an upper end of the cut groove (30). When the fixed cylinder (28) is inserted into the mounting cylinder (18), the claws (31) of the fixed cylinder (28) are attached to the mounting cylinder (18) as shown in FIG. ) Engages with the upper end of the notch (19). In this way, the mounting cylinder (18) is prevented from being deformed such that the width is reduced by the fixing cylinder (28) through the cut groove (19), and the backrest (15)
Is attached to the rear edge of the toilet body (2) via mounting cylinders (18, 18) on both sides (17, 17).

The backrest (15) has both sides (17, 17) warped rearward. Therefore, as shown in FIG. 5, the position of the upper side (16) of the backrest (15) is It is offset backward by a width L from the hinge (7) between the toilet seat (5) and the upper lid (6). The inner space of the backrest (15) is such that when the folded upper lid (6) is flipped up rearward as shown in FIGS. 2 and 5, the upper lid (6) passes through the inside of the backrest (15). It is set so that you can do it. Then, as shown in FIGS. 3 and 5, the toilet seat (5) is raised upward, and the backrest (15) is raised.
When the upper end of the toilet seat (5) is in contact with the upper side (16) of the toilet seat (5), the angle θ of the toilet seat (5) is 90 ° or more. It is stably supported on the upper side portion (16) of the backrest (15) without the need for.

Armrests (32, 32) are attached to both sides of the upper surface of the toilet body (2). As shown in FIG. 4, a cushion (33) is stretched on the upper surface of the armrest (32), and the distal end of the armrest (32) is connected to the toilet body (2) via a support rod (34). It is supported on both sides of the upper surface. That is, a two-stage bearing (44) having bolt holes (45, 45) is vertically provided at the tip of the armrest (32), while a bolt hole (47) is provided at the upper end of the support rod (34). A bearing (46) is projected, and the bearing (46) of the support rod (34) is inserted between the two-stage bearing (44) of the armrest (32), and a bolt hole of the two-stage bearing (44) is inserted. (45,
A bolt (49) is passed through the bolt hole (47) of the bearing (46) and the bolt hole (47) of the bearing (46) via a spacer (48), and a cap nut (49A) is screwed and fixed to the bolt (49). Thus, the tip of the armrest (32) and the upper end of the support bar (34) are rotatably connected.

A bolt is provided on each side (17) of the backrest (15).
A bearing bracket (51) is attached by (50).
A two-stage bearing (52) having bolt holes (53, 53) is provided at the front of the bearing bracket (51), while a bolt hole (55) is provided from the root end of the armrest (32). A bearing (54) is protruded, and the bearing (54) is inserted between the two-stage bearing (52) of the bearing bracket (51), and a bolt hole (53,
53) and a bolt hole (55) of the bearing (54) through a bolt (57) through a spacer (56), and a cap nut (58) is
Screw on (57). Thus, the root end of the armrest (32) is pivotally connected to both side portions (17) of the backrest (15) via the bearing bracket (51).

At the lower part of the support rod (34), a positioning bulge (5)
9) is arranged, and the lower part from the bulging portion (59) is the toilet body (2).
It is detachably fitted into the mounting holes (36B) on both sides of the upper surface of the. That is, fitting recesses (38, 38) are provided on both upper surfaces of the toilet body (2) as shown in FIG.
8), a casing (35) is fitted therein. As shown in FIG. 9 and FIG.
(36, 36A) is protruded, and a screw cylinder (37, 37) having a screw through hole is protruded from the inside thereof. And the front mounting tube
The inside of (36) is a mounting hole (36B) into which the lower part of the support bar (34) of the armrest (32) is fitted.

With the casing (35) fitted in the fitting recess (38), the mounting cylinders (36, 36A) in the casing (35) stand upright from the bottom of the fitting recess (38). Positioning projections (39,
39A), and is positioned outside the positioning projections (39) and further inside the mounting cylinder (36) of the casing (35).
The support bar (34) fitted into (36B) is in a fitted state. Then, screws (40, 40) are inserted into the screw cylinders (37, 37) in the casing (35), and a pair of front and rear support blocks (41) standing upright from the bottom of the fitting recesses (38, 38). , 41) screw holes (43, 43) in the bases (42, 42) provided on the front and rear sides
