PURPOSE:To enable to open and close a door with ease, by preventing loosening of the door by supporting a control member at two points of a shaft supporting portion and an engaging portion, and thereby obtaining smooth advancing and retreating motions of the control member. CONSTITUTION:A clamping portion 68 projected from a clamping surface of a handle 34 faces a clamping hole 69 formed in a support member 40 and it is fixed tightly in place by screws 41. Further, a plate 70 made of a heat-resisting resin is sandwiched between the handle 34 and a door 33, and the plate 70 is formed at its peripheral portion with a stepped portion 71 that is engaged with the peripheral portion of the handle 34. Therefore, the outer periphery of the plate 70 is retracted by a length A from the outer periphery of the handle 34 so that it is not porjected to the outside of the handle 34. Since, with such an arrangement, a shaft supporting section 39 and the clamping portion 68 are made unitary with the handle 34, the length B is made constant. Further, since the clamping hole 69 and an engaging porition 42 are made unitary with the support member 40, the length C is also made constant. Therefore, by fixing the handle 34 after positioning the clamping portion 68 in positioning with the hole 69, positioning of various parts can be achieved with ease at the time of assembling operation. |
