A locking device includes a lever turnably provided relative to a lid member, and switched from an initial state to an operating state against an urging force or self-weight; a lock rod sliding in association with turning of the lever; and a braking device. The locking device locks the lid member in a main member side through the lock rod, and switches the lid member to be unlocked by turning of the lever. The braking device is a rotation damper including a braking shaft with a gear, and placed to approximately conform to a turning center of the lever relative to the lever to damp the lever and the lock rod. The rotation damper includes an operation gear disposed to engage the gear of the rotation damper, associate the gear with sliding of the lock rod, and rotate the gear in a direction opposite to the turning of the lever.

1. A locking device, comprising: a base adapted to be attached to a lid member;a lever rotatably attached the base to be switched from an initial state to an operating state against an urging force or self-weight, and including a main member, the main member having a pressing portion at one side thereof, a connection portion turnably connected to the base for opening and closing a lid member, and an attachment portion provided at the connection portion;a lock rod disposed on the base and sliding in association with turning of the lever, the lock rod having a shaft protruding from one end portion of the lock rod and a tip at another end portion of the lock rod opposite to the one end portion;a braking device, which is a rotation damper, disposed on and attached to the attachment portion to be substantially coaxial to the connection portion of the lever for damping a rotational speed of the lever and a moving speed of the lock rod,the braking device including a member having an attaching portion attached to the attachment portion, a braking shaft, which is an output shaft, for receiving a resistance of a fluid disposed inside the member, and a gear attached to the braking shaft;an operation gear disposed on the base and rotating about a rotational axis thereof, the operation gear including a trunk portion extending in the rotational axis, a first teeth portion having a plurality of first teeth arranged along a circumference of the trunk portion, and a second teeth portion arranged on the trunk portion coaxially to the first teeth portion and separately from the first teeth portion in a rotational axis direction of the operation gear,the second teeth portion having a plurality of second teeth arranged along the circumference of the trunk portion and engaging the gear of the braking device to rotate the gear in a direction opposite to a turning direction of the lever, the second teeth portion having a diameter larger than that of the first teeth portion for increasing a number of rotation of the gear of the braking device to obtain a stable braking force; anda slide member disposed on the base and sliding upon the turning of the lever, the slide member having a shaft portion protruding in the rotational axis direction and contacting the pressing portion of the lever, a rack engaging the first teeth portion of the operation gear to turn the operation gear in association with the sliding of the slide member, and a groove slidably receiving the shaft of the lock rod so that when the lever is turned to push and move the slide member in a first direction, the shaft of the lock rod slides along the groove of the slide member to move the lock rod in a second direction crossing the first direction to switch the lid member to be unlocked,wherein the lid member is adapted to be locked in the main member through the lock rod, and when the lever is turned to move the slide member in the first direction, the shaft of the lock rod slides along the groove of the slide member to move the lock rod in the second direction for switching the lid member to be unlocked and the operation gear simultaneously rotates so that the braking device engaged to the operation gear damps the moving speed of the lock rod. 2. A locking device according to claim 1, further comprising another lock rod slidably disposed with the lock rod to associate with the operation gear, wherein both lock rods are switched between a locking position where the both lock rods are separated from each other to keep the lid member in a closed state, and a release position where the both lock rods approach to each other. 3. A locking device according to claim 2, wherein the operation gear further includes a lock rod teeth portion engaging a rack provided in the another lock rod. 4. A locking device according to claim 1, wherein the braking device damps the rotational speed of the lever and the moving speed of the lock rod when the lid member is switched from being unlocked to be locked in the main member. 5. A locking device according to claim 1, further comprising another lock rod moving in association with the turning of the lever, wherein the operation gear further comprises a third teeth portion arranged coaxially to the first teeth portion and the second teeth portion and separately from the first teeth portion and the second teeth portion in the rotational axis direction of the operation gear to engage the another lock rod, and when the lever is turned to push and move the slide member, the shaft of the lock rod slides along the groove of the slide member and the operation gear simultaneously rotates to move the another lock rod so that the lock rod and the another lock rod move toward each other to switch the lid member to be unlocked. 6. A locking device according to claim 5, wherein the slide member includes a plate portion having first and second sides opposite to each other in the rotational axis direction, the shaft portion and the groove are disposed on the first side, andthe rack is disposed on the second side. 7. A locking device according to claim 1, further comprising a first spring disposed between the lever and the base to rotate the lever, and a second spring disposed between the trunk portion of the operation gear and the connection portion to urge the operation gear in one direction.
