The present invention realizes a locking device for vehicle free from the occurrence of rattle at the portion where the striker is locked. When a lock plate 5 and a latch plate 4 are brought into a locked state and a latch-side recessed portion 4d of the latch plate 4 is engaged with a striker 20, a plate pressing cam 7 rotates clockwise by a restoring force by a coil spring 12, so that its depressing-side cam portion 7e depresses a tip end 6c of a rattle-removing plate 6. A rattle removing-side recessed portion 6d of the rattle-removing plate 6 engages with the peripheral surface of the striker 20, to suppress the rattle of the striker 20. Since the rattle removing-side recessed portion 6d is formed into the shape that matches the peripheral surface of the striker 20, occurrence of rattle can be strictly suppressed.

A regulating device includes a regulating valve with a valve housing, which has a fluid inlet, a fluid outlet, accomodates the valve elements pressing by the fluid pressure in the fluid inlet, biasing element, and is compressed between the valve element and plug, and resists the bias force of the fluid pressure to the valve element. With the development of the fluid pressure, the valve element moves owing to resisting bias force so as to communicate fluid inlet and fluid outlet. The valve element makes the plug move outward relative to the valve housing by bias element so as to reduce the bias force, when the fluid pressure is equal to or more than the preset pressure. A displacement regulation unit coming against plug is to limit its movement and regulate the reduction of the bias force.

A vehicle latch has a housing with a detent and a stop. A lever is pivotally connected to the housing and movable from an install position engaging the housing to an active position pivoted away from the housing. A spring extends from the lever to the housing applying a biasing force to the lever urging the lever to the install position. The spring has a tail portion, a coil section and an opposite end. The opposite end engages the lever. The tail end is moveable to engage either the stop or detent. In the install position, the tail end engages the detent and also engages the lever. In this position, the spring increases the biasing force holding the lever in the install position. The tail end is removable from the detent to engage the stop when the lever is first pivoted away from the install position. This disengages the tail end from the lever and also reduces the biasing force on the lever.
