弁を介して行うようにした実用新案登録請求の範
囲第１項記載の変速機の保護装置。 (3) 電磁弁への圧縮空気供給回路中にスピード
コントローラーを付設した実用新案登録請求の範
囲第２項記載の変速機の保護装置。[Scope of Claim for Utility Model Registration] (1) A protection device for a transmission that changes the rotation speed of a rotating shaft driven by a rotating machine, which includes a gear shift lever provided in the transmission and an air sealed inside with a spring. The piston rod of the cylinder is pivotally connected, and when the supply of compressed air to the air cylinder stops when the transmission stops, the piston rod expands due to the repulsive force of the spring inside the air cylinder, and the gear lever is connected to the transmission. A protection device for a transmission, characterized in that the transmission is automatically returned to the lowest speed position. (2) The protection device for a transmission according to claim 1, wherein compressed air is supplied to the air cylinder via a solenoid valve. (3) A protection device for a transmission according to claim 2 of the utility model registration claim, which includes a speed controller in a compressed air supply circuit to a solenoid valve.
