Claims

[Scope of utility model registration request]

It is arranged in the intake passage 101 of the engine,
A control motor 10 includes an opening sensor 105 and a return spring 104, and is controlled to open and close by a control circuit 115 so that an accelerator operation signal 116 and a signal 105a of the opening sensor 105 match.
In the 6-drive throttle valve 102, the first bevel gear 108 disposed at the shaft end of the rotation shaft 107 of the control motor 106 on the throttle valve 102 side and the control of the rotation shaft 103 of the throttle valve 102 motor 106
A second bevel gear 109 disposed at the side shaft end and a third bevel gear 110 that meshes with or disengages from the first and second bevel gears 108 and 109.
The third bevel gear 110 is rotatable but fixed in the axial direction to a support shaft 111 of the third bevel gear 110, and the support shaft 111 is axially fixed by a spring 112 to the support shaft 111 of the third bevel gear 110. The bevel gear 110 is urged in the axial direction to a position where it meshes with the first and second bevel gears 108 and 109, and the throttle valve 102
When the opening/closing control of the control circuit 115 is not performed normally, due to the mismatch between the accelerator operation signal 116 and the opening sensor signal 105a.
or connected to the sliding rod 114 of the electromagnetic actuator 113 operated by the signal 118 outputted by the
Or, if the spring 1 is integrally formed, and an abnormality occurs in the opening/closing control of the throttle valve 102, the spring 1
12 of the first and second bevel gears 108 of the third bevel gear 110.
, 109 is an electronically controlled throttle valve equipped with a safety mechanism that disengages it.
