A gear arrangement includes a rack, a gear and a flexible member. The rack includes a plurality of teeth. The gear is configured to be engaged with the rack through the teeth. The flexible member is adjacent to an end of the rack. The flexible member is configured to rotate the gear.

A washing machine (100) has a drawer (1) having at least one compartment (10a, 10b, 10c, 10d) for receiving an agent for treating laundry, a supporting structure (2) on which the drawer can slide and a removable retaining device (4) connectable to the supporting structure for delimiting a movement of the drawer with respect to the supporting structure. The removable retaining device is connected to the supporting structure by moving the removable retaining device along a fixing direction. The supporting structure has an engagement element (220) and the removable retaining device has a releasable locking element (420) engaging with the engagement element such that, when the removable retaining device is moved along the fixing direction in order to be connected to the supporting structure, the releasable locking element locks the retaining device in a connected condition.

A slide rail assembly includes a first rail, a second rail, a blocking structure and a locking member. The second rail is movable relative to the first rail. The blocking structure is mounted to the first rail. The locking member is movably mounted to the second rail and configured to abut against the blocking structure, in order to prevent the second rail from being moved relative to the first rail from a retracted position along an opening direction.

A slide rail assembly includes a first rail, a second rail, a first locking mechanism, and a second locking mechanism. The second rail can be displaced with respect to the first rail. The first locking mechanism and the second locking mechanism are arranged at two different portions of the second rail respectively and are configured to lock the second rail at two predetermined extended positions respectively. The first locking mechanism and the second locking mechanism can be operated so that the second rail is no longer locked by the locking mechanisms and can be retracted with respect to the first rail.

A case includes a shell, a sliding member, and an operating member. The shell defines a through hole. The sliding member includes an abutting portion. The operating member is rotatably fixed to the shell and slidably connected to the sliding member. The operating member rotates in a first direction to drive the sliding member to slide in a second direction and the abutting portion abuts the stopping portion to be pushed out of the through hole. The operating member rotates in a direction opposite to the first direction to drive the sliding member to slide in a direction opposite to the second direction and the stopping portion moves into the through hole.
