Abstract:
1. A link type throttle valve control device in a throttle body, the device comprising; a throttle valve shaft which crosses an intake passage provided in the throttle body, is mounted with a throttle valve for opening/closing the intake passage, and is supported rotatably to the throttle body; a throttle valve operation shaft, which is supported rotatably to the throttle body, and is mounted with a throttle body operation dram provided with an opening valve end inserting hole and a closing valve end inserting hole at an end portion thereof; a stay plate, which is provided with a first cable guide inserting hole and a second cable guide inserting hole, and mounted at the throttle body; and a link mechanism comprising a first link lever mounted at an end portion of the throttle valve operation shaft, a second link lever mounted at an end portion of the throttle valve shaft, and a connection lever for connecting the first link lever and the second link lever, wherein rotation of the throttle valve operation dram operated by an operator is transmitted to the throttle valve shaft through the link mechanism and thereby, the intake passage is opened/closed by throttle valve, wherein a throttle valve operation shaft is rotatably provided at a stay plate, where the throttle valve operation shaft is mounted with a throttle valve operation dram and a first link lever, and an opening valve end inserting hole and a closing valve end inserting hole are provided in the throttle valve operation dram, wherein a first cable guide inserting hole and a second cable guide inserting hole are formed at the stay plate, wherein the stay plate is rotatably provided coaxially with a longitudinal axial line of a throttle valve shaft, and the first link lever and the second link lever mounted at the throttle valve shaft are linked by a connection lever, and wherein the stay plate is rotated to be provided at a desired position with respect to the throttle valve shaft, and the stay plate is screwed and fixed at a throttle body by screws to keep this state.
