Is provided with a handrail 22. A space S is provided between the seat 5 and the floor 1. An electric heater 23 is provided in the space S. The electric heater 23 is integrally formed by a heater unit 24 arranged in a plane. The heater unit 24 has an interval S _{1 with} respect to the seat 5.
Is smaller than the interval S ₂ to the floor (S ₁ <
S ₂ ) is attached to the seat 2. The seat 5 has a surface facing the heater unit 24 formed on an uneven surface 25. In the heater unit 24, a cord-shaped electric heater 23 is arranged between two thin holding plates 26 in a meandering manner, and an insulating member 28 such as urethane foam is provided inside. Further, the heater unit 23 is fixed to the side plate 29 of the seat portion 5 with screws 31 via support members 30. A heat insulator 33 is interposed between the heater unit 24 and the support 30.

In the space S, the wall surface 3 and the floor surface 1
Between them, a partition plate 34 is provided diagonally. The partition plate 34 serves to reflect the heat generated from the heater unit 24 and to prevent foreign matter such as dust from entering the interior of the space S. That is, even if the luggage is placed in the space S, the small luggage slides down the diagonal partition plate 34 and falls on the floor 1. In addition, large luggage is prevented from entering.

In the second embodiment shown in FIG. 3, the heater unit 24 has a space S far from the wall 3 and a space S ₃ with respect to the seat 5 smaller than a space S _{4 with} respect to the floor 1. (S ₃ <S ₄ ). Also,
