A canopy includes an annular central portion which is mounted on the ferrule, and a surrounding portion which surrounds the central portion and which has a plurality of first through holes displaced angularly from one another. A plurality of ribs are made of wooden material, and are disposed on the ferrule at an underside of the canopy. The ribs are displaced angularly from one another about the axis. Each rib includes a proximate end portion which is pivotally mounted on the ferrule, and a distal end portion which extends from the proximate end portion in a first direction radial to the axis. The distal end portion has an inner rib surface which abuts against the canopy, an outer rib surface opposite to the inner rib surface, and an annular inner peripheral wall which extends from the outer rib surface through the inner rib surface and which defines a groove that is registered with a respective one of the first through holes in a second direction transverse to the first direction. A plurality of sleeve members have inner peripheral wall surfaces confining accommodating chambers for sleeving on the distal end portions of the ribs, respectively. Each rib has an outer surrounding wall surface surrounding the inner peripheral wall surface. The outer surrounding wall surface includes an upper portion which defines a second through hole that extends through the inner peripheral wall surface to communicate with the accommodating chamber and that is arranged at such a position so as to register with and be disposed between the respective first through hole and the groove in the second direction when the respective sleeve member is sleeved on the distal end portion. A plurality of tightening members are made of a material different from that of the ribs. Each tightening member includes a first portion with a shank which is retained in the groove of the respective rib and which is formed with an internally threaded surface extending along the groove, and a second portion having a shaft formed with an externally threaded surface which passes through a pair of the first and second through holes, and which engages threadedly the internally threaded surface of the first portion so as to secure the canopy and the upper portion of the respective sleeve member to the distal end portion of the respective rib.
