A pair of main poles 3, 3 provided with rear handles 4, 4 are mounted substantially perpendicular to the main shaft 2.

On the main poles 3, 3, bottom poles 5, 5 and chair poles 6, 6 are fixed horizontally. The front ends of the chair poles 6, 6 are bent downward, and the bent bodies 6a, 6a and the bottom poles 5, 5 are joined to form a square frame. Also, the foot rests 7, 7 are rotatably attached to the bent body 6a and the ends of the bent body 6a. The chair pole 6 and the chair pole 6 are provided with a sheet (not shown).
Passengers can sit down. Reinforcement poles (not shown) are provided between the main pole 3 and the main pole 3, between the bottom pole 5 and the bottom pole 5, and between the chair pole 6 and the chair pole 6, as appropriate.

An L-shaped armrest pole 16, 16 to which an armrest 15 is attached is fixed to the bottom poles 5, 5, chair poles 6, 6, and main poles 3, 3. The well-known rotatable front wheels 8, 8 are connected to the armrest pole 1
At the lower end portions of 6 and 16, they are attached via an attachment body 21. In addition, the rotatable front wheels 8, 8 are connected to an axle 8
a is rotatable, and a rotatable support 9 is attached to the axle 8a. A fixed shaft 20 is rotatably fitted to the support 9 and an attachment 21 is provided. Accordingly, the front wheels 8, 8 are rotatable on the axle 8 a and can change direction via the fixed shaft 20.

A pair of front handles 2 bent in an L-shape are provided.
5 and 25 have the fixed shaft 2 having a tip portion formed in a cylindrical shape.
0 and 20 can be inserted. That is, the front handles 25, 25 are attached to face the rear handles 4, 4, and can be easily formed by using the fixed shafts 20, 20, and can be detachably attached. Can be removed when not needed. Therefore, when the front handles 25, 25 are used, they may be inserted into the outside (or the inside) of the fixed shafts 20, 20 (see FIG. 1), or removed when not in use and stored in another place. (See FIG. 2).

In the wheelchair having the above-described structure, the passenger and the attendant are moved in a state in which both the passenger and the attendant face forward as in the related art by pushing the passenger and pressing the rear handles 4 and 4. When the attendant pushes the front handles 25, 25 with the handles 25, 25 attached thereto, the attendant and the occupant can move while facing each other. Therefore, the attendant can have a conversation while watching the state of the passenger, and can always see the state of the passenger. Also, when the passenger gets off the wheelchair with the front handles 25, 25 attached, the front handles 2
It functions as an auxiliary rod which can be easily raised by being gripped by the members 5 and 25.

The front handles 25, 25 are configured to be detachable using the fixed shafts 20, 20 of the front wheels 8, 8, but may be of a fixed type. The attachment of the front handles 25, 25 is not limited to the fixed shaft 20,
The wheelchair frame (bent body 6) faces the rear handle 4.
Needless to say, if possible, it can be configured to be detachable using any of the methods a, 6a) and the like.

Further, the rearview mirror 30 can be attached to other parts besides the front handles 25, 25, and the occupant can eliminate anxiety about moving forward by the rearview mirror 30. For example, as shown in FIG. 4, a relatively large rearview mirror 30 </ b> A having a rectangular shape or the like is inserted using the fixed shaft 20 at a position where both the attendant's face and the passenger's face can be seen. The rearview mirror 30A is attached to a support 80 via a ball joint 82, so that the direction of up, down, left, and right can be freely changed.

Therefore, by inserting the support 80 outside (or inside) the fixed shaft 20 and adjusting the rearview mirror 30A to an appropriate angle, the rearview mirror 30A can be moved through the rearview mirror 30A.
Both the attendant and the passenger can see their faces, and they can talk while watching the passenger, and can always see the passenger. In addition, when the passenger gets off, by rotating the column 80 so that the rearview mirror 30A is parallel to the traveling direction, the passenger can get down without obstruction, and by removing the column 80 from the fixed shaft 20,
It can be stored when not in use.

The support column 80 may be configured to be detachable (or fixed) by attaching a member corresponding to the fixed shaft 20 to the left end of the bottom pole 5 or the like. Also, by using a large mirror, the rearview mirror 30A allows both the caregiver and the passenger to see the face, and also allows the rear view to be seen, thereby eliminating anxiety about moving backward.

The lamp L is turned on and off by a limit switch 41, and FIG. 3B shows a circuit diagram and a detection unit. Four fan-shaped (45 °) detection pieces 40 are attached to the main shaft 2, while the detection end 44 of the limit switch 41 can be abutted. Also, the detection end 44 of the limit switch
Is biased by a spring, and is conductive when swinging to one side. Therefore, the fan-shaped detection piece 40
Contacts the detection end 44, and the conduction state is maintained while the detection end 44 swings. Therefore, in the fan-shaped (45 °) detection piece 40 shown in FIG. 3B, the lighting time and the extinction time of the lamp L are the same.

When the main shaft 2 of the wheelchair of the above configuration rotates clockwise (retreat), the detecting piece 40 swings the detecting end 44 rightward, turning the limit switch 41 "ON", and turning on the power supply (dry cell, solar battery). Lamp (LED etc.) L via battery etc.
Is turned on, but when the detecting piece 40 does not hit the detecting end 44, the lamp L is turned off. On the other hand, when the main shaft 2 rotates counterclockwise (forward), the detecting piece 40 is
Swings to the left, but the limit switch 41
F "is maintained, and the lamp L is kept off. As described above, when the wheelchair retreats, the lamp L blinks, so that the surrounding people can also pay attention.
This is effective when only the passenger moves without an attendant. It is needless to say that the lamp L may be configured to blink when moving forward in addition to when moving backward.
