　′[Claims for Utility Model Registration] 1. The invention is characterized by being provided with an actuator that holds the carburetor throttle valve of an internal combustion engine at a set idle opening in a predetermined engine operating state, and a delay mechanism that delays the holding operation of the actuator. Idle up device. 2. A first actuator for maintaining a carburetor throttle valve of the internal combustion engine at a first set idle opening degree is provided, and works in conjunction with the first actuator to slightly open the throttle valve from the first set idle opening degree. A second actuator that maintains a second set idle opening is installed alongside the first actuator, and has a starting end opened in the intake passage downstream of the throttle valve and branches at a branch point in order to operate the first actuator and the second actuator. negative pressure passages each having an open end are provided in the first actuator and the second actuator, and the negative pressure passage between the intake passage and the branch passage is provided with a negative pressure switch that opens when an electric load is applied to the internal combustion engine. A temperature sensing valve that opens below a predetermined engine temperature is provided in the negative pressure passage between the branch point and the second actuator, and the negative pressure from the negative pressure switching valve to the second actuator is The idle-up device according to claim 1, wherein the passage is provided with a throttle portion. 3. The idle-up device according to claim 1, wherein the throttle portion is provided in the negative pressure passage between the branch point and the temperature sensing valve. 4. The idle up device according to claim 1, wherein the throttle portion is provided in the negative pressure passage between the negative pressure switching valve and the branch point. 5. The eye according to claim 1, wherein the throttle part is provided in the negative pressure passage between the temperature sensing valve and the second actuator.
