Provided is an umbrella, the canopy of which can be moved in the angle of inclination according to the position of the sun while the stick of the umbrella being retained or fixed by a support member for supporting the upright state of the stick, and the inclination angle of which can be locked (or held) at the moved position so that the umbrella allows the user to use the two hands not only in the shade in the fine, hot weather but also in the rain. The umbrella comprises a joint portion for giving the umbrella stick an inclination angle so that the stick is held at multiple stages in the inclination angle over a cylinder covering the joint portion. A joint member includes a pin notched to have an elastic portion, or an elastic portion disposed in the recess of the joint member. A plurality of recesses are formed in the leading end of the protrusion of the joint member in the same direction as the axial direction of the pin. Protrusions corresponding to the recesses are formed on the recess of the joint member, or the elastic portion is disposed in the recess of the joint portion. Moreover, protrusions are formed on the inner wall of the leading end portions of the recess of the joint portion. A plurality of recesses corresponding to the protrusions are formed in a sector shape in the bulging side face of the joint portion. A lock mechanism is mounted in an outer cylinder or a pin. The umbrella is manufactured by applying a sheet member, which is prepared by adding a waterproofing property to the sheet member having a light/heat shielding property, to the canopy of the umbrella.
