A trigger-type liquid sprayer of the present invention is provided with a liquid sprayer body 2 having a nozzle 21 and a trigger lever 22 and a shroud 3 covering the liquid sprayer body 2 and sprays a liquid from a spray hole 211 in the nozzle 21 by a pulling operation of the trigger lever 22. The nozzle 21 is rotatable with respect to the liquid sprayer body 2 and provided so as to open/close a flow passage for the liquid according to a rotational position of the nozzle 21 when an operation lever 24 mounted on the nozzle 21 is rotationally moved, and an abutment portion 31 for positioning the nozzle 21 at a position where the flow passage is opened through abutment of the operation lever 24 is provided at the shroud 3.

1. A trigger-type liquid sprayer comprising: a liquid sprayer body including a nozzle and a trigger lever and a shroud covering the liquid sprayer body in which a liquid is sprayed from a spray hole of the nozzle by a pulling operation of the trigger lever,the nozzle being rotatable with respect to the liquid sprayer body and provided so that a flow passage of the liquid is opened and closed according to a rotational position of the nozzle when an operation lever mounted on the nozzle is rotationally moved between opened and closed positions, respectively;an abutment portion being provided at the shroud for positioning the nozzle at a position where the flow passage is opened by having the operation lever abutted to the abutment portion in the opened position;a first cylindrical portion including a first groove; anda second cylindrical portion that is radially offset with respect to the first cylindrical portion, the second cylindrical portion including a second groove, and the second cylindrical portion being configured to rotate with respect to the first cylindrical portioni) so as to radially align the second groove with the first groove to open the flow passage, andii) so as to radially misalign the second groove with respect to the first groove to close the flow passage, whereinthe trigger lever travels along an actuation path in a pull direction and an opposing release direction, the pull direction corresponding to a direction of the pulling operation on the trigger lever;the operation lever includes a rod that is fixed to the nozzle, a knob that is fixed to the rod, and a projection that is fixed to the knob, such that, when the flow passage is closed by the nozzle through rotational movement of the operation lever to the closed position, the rod is provided to be accommodated in front of the trigger lever, so that the trigger lever is inhibited from extending further along the actuation path in the release direction, the knob is provided so as to extend, in the pull and release directions, across a side of the trigger lever, and the projection is provided as to extend behind the trigger lever to inhibit the trigger lever from extending further along the actuation path of the trigger lever in the pull direction;the trigger lever includes a space provided by a recess in a front face portion of the trigger lever on a side of the trigger lever including a rotation center, the recess being a stepped portion;the stepped portion includes a reinforcing rib that extends between a base surface of the stepped portion and a depth surface rising from the base surface, the base surface extending in the pull and release directions, and the depth surface and the reinforcing rib extending vertically from the base surface; andwhen the operation lever is in the closed position, the reinforcing rib functions as a stopper for the operation lever by contacting the rod of the operation lever. 2. The trigger-type liquid sprayer according to claim 1, wherein: the first cylindrical portion is a portion of a spin element and is fitted in the second cylindrical portion, which extends in a direction opposite to the spraying direction of the nozzle; andthe positioning of the nozzle is carried out only by abutment between the operation lever and the abutment portion. 3. The trigger-type liquid sprayer according to claim 1 used for spraying of a liquid containing sodium hypochlorite. 4. The trigger-type liquid sprayer according to claim 1, wherein: a surface of the trigger lever facing the release direction, which forms a contact area for the pulling operation of the trigger lever, includes the recess that forms a space along the actuation path in front of the trigger lever at an end of the trigger lever that is proximate to the nozzle; andwhen the flow passage is closed by the nozzle through rotational movement of the operation lever to the closed position, the rod of the operation lever is provided to be accommodated in the space, in front of the trigger lever, so that the trigger lever is inhibited from extending further along the actuation path in the release direction. 5. The trigger-type liquid sprayer according to claim 1, wherein, when the operation lever is in the closed position, the trigger lever extends, in a direction away from the nozzle, beyond the knob. 6. The trigger-type liquid sprayer according to claim 1, wherein, when the operation lever is in the closed position, the rod extends from the nozzle at an angle so as to extend from a center area of a front surface of the trigger lever to a side area of the front surface, where the rod is fixed to the knob, the knob having a planar shape that extends along the side of the trigger lever, in the pull and release directions, to respective points beyond rear and front surfaces of the trigger lever. 7. The trigger-type liquid sprayer according to claim 1, wherein, when the operation lever is in the closed position, the projection fills a space between a rear surface of the trigger lever and a portion of the liquid sprayer body.
