Abstract: A grip main portion includes supporting members disposed on both sides thereof. An assist grip can be rotated to switch between a non-operational position and an operational position projected into a compartment through the supporting members. An attaching portion of the compartment is provided with the first and second temporary attaching holes. One of the supporting members is provided with a pole protrusion passing freely through the first temporary attaching hole. The other supporting member is provided with an elastic protrusion to be engaged when inserted into the second temporary attaching hole. The elastic protrusion can be pulled out from the second temporary attaching hole when the grip main portion is rotated by a predetermined angle with the pole protrusion being pulled out from the first temporary attaching hole.

Abstract: An injection nozzle for blowing air or injecting solvents reduces noise level and facilitates cleaning of injection passages. The injection nozzle includes a nozzle body provided with an opening and an inlet passage communicating with the opening. A plurality of grooves are provided on top and bottom sides of the nozzle body respectively. The nozzle body is also provided with upper and lower cover members, which can be selectively opened or closed. When the cover members are closed, an expansion chamber is defined by the opening and injection passages are defined by the grooves. The fluid to be injected from the inlet passage is expanded once in the expansion chamber and is then distributed through the injection passages for injection. Such expansion and contraction produces an effect of reducing noise level at the time of injection. Furthermore, the insides of the expansion chamber and the injection passages can be cleaned with ease by opening the cover members.
